SiH, That distinguished Ministerial position, which constituted you chief officer of the Government Schools of Design, and especially con- nected you with the progress of British manufactures and commerce, coupled with your personal accomplishments as a deep student and sincere lover of Art, assure me that you will regard with interest the present attempt to contribute to the advancement of one of the most important branches of national industry. From the kindness it has been my privilege to experience at your hands, I feel confident that you will make full allowance for the many imperfections which it is but reasonable to anticipate in a work, the materials of which have been collected and wrought mto their present form under the constant pressure of arduous and distracting engagements. Fully relying on the interest of my subject, but mistrusting my ability to treat it worthily, I venture to dedicate the present volume to you, And have the honour to be, Sir, Your obliged and most obedient Servant, M. DIGBY WYATT. 77 dreat Russell Street, July 7, 1852. PREFACE. A PERUSAL of the admirable, though too brief, remarks upon the subject of metal-work contained in Mr. Pugin's " True Principles of Christian Architecture," first suggested to the Author of the present work how essential it was for the progress of the industrial arts that the unsatisfactory system of industrial design, which obtained universally in this country at the epoch of the publication of that work, should be greatly modified, if not entirely remodelled. In acknowledging the correctness of the undeniable proposition, that every material, insomuch as it differs in organic constitution, should vary correspondingly in the form and proportion into which it should be wrought, an admission was made, that the ordinary system of copying in metal forms proper for stone, and in stone forms proper lor metal, wood, &c., was as contrary to the true canons of good taste, as it was subversive of any prospect of consistent originality. In order to succeed in any divination into the course most advantageous to pursue in the Future, it was first necessary to realise the successive steps by which various degrees of excellence had been attained in the Past. In entering on the threshold even of such a course oi' inquiry, the paucity of materials for the study ol the art of design in metal -work presented itself With the exception of Mr. Shaw's engravings, which comprise a series of objects, many of which exhibit most contra- dictory theories of composition ; with the exception, of Mr. Pugin's own designs ; — of a few scattered notices in the " Gentleman's Magazine," and the " Archajologia," and of two or three plates (of the Lynn Cup, William of Wykeham's crozier, &c.) in Carter's works, there may really be said to have existed no English authorities for reference on the subject. Social and religious troubles and political revolutions had contributed to destroy the majority of those treasures of gold, silver, and iron, which ancient records prove to have formerly abounded in this country ; while a general ignorance ii PREFACE. of their value, and apathy to their beauty or utihty, combined to conceal the exist- ence of the few which happy accident, rather than design, had preserved to modern times. It is only of recent years that the energies of Mr. Henry Shaw, Mr. Albert Way, Mr. C. J. Richardson, Mr. Delamotte, and of the various Archaeological and other Societies, have succeeded in bringing to light many treasures of art which had long lurked in obscurity and unappreciated. From the plate-chests of the various City Companies and municipalities throughout the kingdom, from the recesses of old family chests and corner cupboards, and from the more jealous custody of College dignitaries, rich harvests have already been gathered in. Although through the labours of those to whom allusion has been made many interesting objects have been brought to liglit, figured, and described, the collection, could it but be brought together, would be found to consist of a series of objects precious to the antiquarian rather than to the artist, to the illustrator of obsolete customs and usages rather than to the student of the history and theory, or the practical designer, of metal- work. When, in the year 1844, the Author left this country with the object of extending his professional studies on the Continent, those investigations were yet but little advanced, and a few only of those illustrations had appeared which have since made the aspect of the primteval and mediaeval vessels and objects manufactured in this country in gold and silver familiar to the eye. The apparent dearth of interesting materials from which any generalisation as to appropriate processes, forms, and orna- ment, might be extracted, served to stimulate the exertions of the Author. He was thus induced, during his residence abroad, to obtain access to, and to make drawings of, many objects, the peculiar types of which appeared valuable as suggestive of the principles which, combined, might be regarded as forming the grammar of metal- work, considered as a subsidiary branch of the Fine Arts. During the course of these studies, some particulars were collected throwing light upon the practices of past ages and of those periods when the various styles of design and manipulation were at their highest point of perfection. On the Author's return to England, he found, that although during his absence from this country much had been done, there was still ample scope, and indeed great need, for some more copious illustration of the subject. He was hence induced to take counsel with many kind friends, interested both in antiquarian and in technical pursuits, and the result was, that he became intimately connected with the Archseological Institute and the Society of Arts. To both bodies he feels grateful for the kind encouragement he received in his labours, — to the former, for much sympathy and assistance in the PREFACE. iii collection of materials, — to the latter, for the favour with which they received the papers on enamelling, and on other more or less dormant processes of the gold- smith's art, which he at various times contributed to their Proceedings. Thus encou- raged, the Author determined to enlarge his stock of illustrations, and to arrange the information he had brought together into a form which might supply to others the knowledge it had cost him much labour to collect, and the conclusions at which he had arrived upon the subject. In carrying out this object grave difficulties have presented themselves. Imper- fect literary preparation, the necessity of preventing the study of one object from encroaching on that of others of at least equal importance, and continued occu- pation of an exciting and laborious kind, have all combined to render the task an arduous one, and the performance of it far from what it might have been in abler hands and under more favourable circumstances. In one particular, however, he feels himself to have been especially favoured. From many learned and artistic friends, by whom he was surrounded, he received the kindliest sympathy, and much valuable assistance. To his pupil, Mr. William Surges, whose deep study of the mediaeval arts rendered his services peculiarly valuable, the Author is indebted for many literary and pictorial contributions. To Mr. Edward Falkener, whose profound researches into classical antiquity have not prevented his accumulating inestimable material for the illustration of Christian art, the work is indebted for subjects introduced into no less than six plates, viz. Nos. XV., XXVII., XXIX., XXX., XXXIL, XLII. From the portfolios of Messrs. F. C. Penrose, E. Willson, J. Gibson, C. Barry, jun., E. Barry, J. Johnson, E. A. Spurr, and Roberts Gowan, many valuable subjects have been most liberally contributed ; and the Author takes the present occasion to express his thanks and acknowledge his obligations to those gentlemen. From Mr. Albert Way, the extent of whose researches into the technicalities of the manipulative processes of metal-working in the middle ages, has been testified by numerous admirable essays, printed in the " Archseologia " and in the " Journal of the Archaeological Institute," much information and sympathy were derived ; and it is probable that but for the kind encouragement of that gentleman the present work would never have been laid before the public. In Messrs. Day and Sons the Author has met with publishers from whom he has received the most considerate treatment, and who have spared neither cost nor pains to reproduce the original drawings with the utmost perfection of chromo- lithography.

It has been well remarked, by no less a man than the immortal Locke, " that the mechanism of the arts contains more true philosophy than the systems of philosophers;" and in that observation he has perhaps only echoed the great dogma of Lord Bacon, "that the history of the mechanical arts is the most important branch of trne philosophy." These two splendid apophthegms, pregnant as they are with meaning, have been adopted with remarkable felicity by the French Encyclopedists, as mottoes to that portion of their great work which treats of the industrial arts. The English are indebted for the proud position they at present occupy in the world of manufacture, and the reputation they have gained for the intrinsic excellence of their productions, to their deep and persevering recognition of the absolute utilitarian importance of the studies recommended by these and other great economists ; it is, however, only very recently that they have commenced the endeavour to superadd to their technical perfection some little of the refining influence of grace, and to inves- tigate, in an earnest spirit, those fundamental principles which should govern and modify the specific nature and form of the desired alliance of use and beauty. One of the most important of those general laws which have been given to us, as the result of such inquiries, is that of the imperative necessity of adopting, as the basis of the design of objects executed in any material which nature offers to our use, a system of ornamentation strictly in harmony with the structure, chemical and mechanical, of the finished article — with the value of the materials of which it is composed — an association of idea connected with them, and with its purpose and probable destination. The systems of decorative treatment of two materials, similar in some essential qualities, but diverse in others, should differ in the exact ratio of those discrepancies, and from the continual and thoughtful observance of these objective conditions of nature, a scale of appropriate common-sense design would be in time established, within the limits of which the artist might exercise his suijeclive power without fear of extravagance. Thus in the manufacture of metals any attempt at novelty, to be satisfactory to the cultivated taste, must be executed in subservience to at least a threefold influence : firstly, to that imposed by the elementary structure of the metal, whether gold, silver, iron, or bronze; secondly, to that deducible from all the processes of manufacture human ingenuity can devise, which must be conducted in obedience to the peculiar properties of each metal; and thirdly, to the condition of emotions dependent on a legitimate and sensible association of idea, founded upon a study of all that has been done in the best ages of the past. Bearing in mind the nature of these three dominant influences, w^e have, therefore, arranged our remarks under three corresponding divisions : — Theory, Practice, and History. Gold, silver, bronze (a compound of copper, tin, and other alloys), and iron, are the principal metals pressed into the service of the arts, and the respective characteristics of design which best harmonise with their primary conditions of structui-e may be thus broadly indicated. Gold is the most valuable of all metallic substances, with the exception of platinum ; it is the most malleable and ductile, the most beautiful in colour and brilliancy of surface, and it is the least susceptible of oxidation. From the possession of these quahties we may assume that it is most fitly destined for employment, in a massive form, in small objects only, on account of its rarity ; in sheet, filagree, and wire, of the most exquisite tenuity, on account of its mallea- bility and ductility ; in the highest decoration, extended superficially, on account of its colour and beauty of surface ; and as a covering, reivtement, or protection to other metals more easily injured by exposure to the air, on account of its extraordinary powej- of non-oxidation. THEORY. Silver is next in value, ductility, and malleability to gold; and though liahle to tarnish, is easily cleaned by friction. It seems, therefore, naturally adapted to be worked with the hammer in plates, and beaten to its requisite degree of high or low relief, to be used in the massive form in larger objects than gold, not to be so susceptible of extension over large surfaces, but admirably adapted to protect and ornament the baser metals, in all household vessels and implements which require frequent rubbing to keep them tit for use. Bronze, from its intractability and brittleness, excessive hardness of surface and facility of fusion, seems to demand for itself a completely different line of treatment from silver. Casting and chasing appear its proper and legitimate province, and it lends itself with singular felicity to the reproduction of the highest order of sculpture. Its compact texture, evidenced by its peculiar sonorous properties, dictates a system of hollow casting, and it is only in the most barbarous ages that it has ever been used in the massive form. The twofold nature of the properties of Iron, in its cast and in its wrought state, are so well kno^vn that it is scarcely necessary to dwell upon them ; but we may be content with remarking, that as the usual office of iron is essentially to strengthen and construct, it is most consistently employed, excepting where it serves as a support, in the massive form of solid casting ; or when bent and wrought in simple forms upon the anvil, filed to regularity of surface and angle, and punched into open work plates by intense force ; and thus elaborated, it should be strictly appropriated to utilitarian services. Copper, from its malleability and toughness, is peculiarly adapted to the formation of domestic vessels by hammering and stamping. The general scheme of manufacture thus dictated by nature, it has been the happy prerogative of man, during almost the whole period of his history, to adopt and perfect, with all the energy and skill with which he has been mercifully endowed by that Providence which has ordained that " by the sweat of his brow he shall live." Sculpture in metal, partly on account of the much greater ductility and tenacity of the material, and partly on account of its peculiar colour and power of reflecting light, can rarely, however high its deo-ree of finish may be carried, be mistaken for that which it professes to imitate. Hence it arises that elaborate execution of details may, and indeed should, be earned in metal to the most minute perfection. Works in gold or silver should, as a general rule (except in instances where an ovei-powering display of wealth is intended, ni which case art does not much signify), be confined to small dimensions, and those relatively correspondent to the associations of idea connected with the rarity and value of each. It was from inattention to these conditions that many of the largest pieces of plate in the Great Exhibition of 1851 failed to excite a proportionate amount of interest, and that the eye dwelt with much greater complacency upon the smaller than upon the larger objects. It has been ably remarked by a writer in the "Journal of Design" (vol. i. p. ,3.5),— if we are not mistaken, by the eminent sculptor, Mr. .lohn Bell,— that " the superior strength and compactness of metal over other materials, afford the opportunity also for superior fineness of parts in ornaments. Those piercings which would be inconsistent with firmness in wood or porcelain, are yet durable in metal; for convenience also and utility its weight necessitates, in many cases, a thinness and lightness of treatment. In many instances, such as in the use of the precious metals, to save cost in material, it is advisable to obtain thinness ; most of our articles of silver being thus made of plates beaten up into the required form, the ornament being added afterwards. This has to he done carefully, or holes are apt to occur, injuring or spoiling the article ; but if well done, the process of hammering necessary to bring them to the required form produces a superior firmness of substance. " Lightness in the casting, also, of all metals, is considered a beauty. In the old bronze of Cellini's time the greatest care seems to have been taken to cast the work of an even thinness, and great attention accord- ingly had to be paid to the cwin; or core, of the mould, so as to leave in all parts an even space between that and the mould of the surface (for the melted metal to run into) to produce the desired effect. That most useful of all metals, iron, is no exception to this rule. No doubt in some cases, where it is put to purely utilitarian purposes, such as girders to support great weights, railway engines, tubular bridges, &c., the - lightness that is sometimes introduced can hardly be said to be directly that of ornament; yet, in some cases of utility, its natural adaptation produces the most pleasing appearances. How almost fairy-like (although the eye has now become accustomed to it) is the effect of a suspension-bridge! And this is a good case in point; for here the employment of iron for a strictly utilitarian purpose presents a pendant fabric, at a distance especially, apparently of an almost web-like tenuity, and of infinitely greater lightness in effect than would THEORY. Xlll have arisen from the employment of wood, stone, or hrick. Considering this metal more strictly in an ornamental view, we may almost lay it down as a canon that the lightest article will, ccsteris parlhiis, be the best in effect. In lamps, candelabra, and even grates, fenders, and fire-irons, if we meet with a pattern that is agreeable, it will almost always be found to be fine and delicate, comparatively ; and this observation will apply to all works in metal. From the tea-urn to the bronze statue, lightness of effect is desirable. In statues, which are indeed but the highest kind of ornament in form, how much more adapted to the nature and colour of the material, and therefore how much better in effect, is the well-known Mercury of John of Bologna, with the turn of each limb displayed against the sky, than the heavy massive works we sometimes observe, where heavy folds of drapery shroud the figure, and where scarcely any outline is relieved save that of the cloak that envelopes it.' " We are too apt, in endeavouring to overcome the mechanical difficulties of working inherent in any substance, to ' overleap the mark, and fall on the other side.' Thus, in bronze and brass work, we rush into a frittery, flimsy imitation of fluttering draperies, &c., in order to exhibit our perfect mastery over the difficulties of complicated casting. Now, by another and simpler mode of treatment, the effect produced might have been infinitely better. We might at once acknowledge the grandeur and propriety of a majestic colossal sphynx in granite or porphyry, but let Dorothea or Una, or any other popular piece of elegance, be worked out in one of the same materials, and our only feeling will be, how very much better it would have been in marble, alabaster, or biscuit. It is ten chances to one, too, if, in this attempt to display our manual dexterity, we do not altogether lose sight of propi'iety of form and adaptation of line to the direction of support, &c. Thus in some of those trebly- twisted scrolls, bent in all kinds of ways, and surmounted by all sorts of fruits, flowers, dolphins, cupids, monsters, &c., we are annoyed with a mechanical facility which, more moderately exhibited, might have pleased as much as it frequently disgusts." It may appear scarcely necessary now to reiterate the dogma, that not only should designs for metal differ from those adapted for execution in wood or stone, but that designs for any one metal should be made different in style from those suited for any other. All the world will doubtless agree in the justice of the proposition, but how few there are who act upon it ! One of the main reasons for this neglect consists in the fact, that until very recently the study of the theory of design has never been made specific. The one heau ideal has been regarded as lovely in any form; and so long as curves were graceful, and limbs and features nicely turned, it was considered to make but little difference whether they were adapted for execution on a great scale in cast-iron or in stone ; or whether they shrank into miniature monuments, in silver testimonials, or Dresden or French biscuit. Our present endeavours being to realise a few of the special conditions of metal-work, we shall proceed to an examination of those directly affecting iron, bronze, gold, and silver, commencing with IRON-WORK, AND THE PUINCIPLES OF ITS TREATMENT.* As in philosophy we find a certain number of the thinking world unwilling to concede value to anything the utility of which they cannot clearly pei'ceive, so, among those practically engaged in the great work of manufacturing production, a large body of individuals may be found who yield a title to merit, only in proportion to the degree of utilitarian contrivance manifested by the designer of any of the staple articles of commerce. It is to the class of men in the iron trade who hold such tenets that we are mainly indebted alike for wonderfully- ingenious and delicately-adjusted beams, girders, machines, roofs, &c. ; and for the particularly ugly forms in which, until within a very recent period, these objects have been habitually designed. There are, again, others in philosophy who do not allow that any narrow scale of human wants and necessities can correctly determine intrinsic value in art or science ; while, in the province of manufacture and its design, many may be met with who, dwelling on the existence of an inherent grace in form and proportion, attach a secondary value to the utilitarian portion of every object, — men who, in the speciality of iron-work, would determine the merit of a pump or a lamp-post by the possession of certain picturesque or graceful charac- teristics, rather than by the quantity of water raised by the one, or the facilities for the distribution of light afforded by the other. * Many of these remarks originally !i]i]K'nrctl in a paper written by tlic autl.or for tin- "Journal of Design." THKORY. To the first class of bigots (the Utihtarian), we may fancy, bdong the careful cast-iron Constructionists, who efuerally build railway sheds ad infinitum, and bridges ad nauseam, with more skill than taste; to the second (the Idealist), the poetical and sometimes tumble-down genii, who raise imaginary towers on "the baseless fabric of a vision," cover dog-kennels with crockets and finials, turn stoves and clocks into cathedral fa9ades, make brid<>-es w^here w^ater flows not, and too often sacrifice comfort and convenience to ornament and effect. In cases wlierc the diversities of opinion on matters of design to which we have referred exist, the differers beim^ intelligent, we usually meet with a degree of mutual tolerance; while, in the present day, the system of the division of labour so circumscribes even such men's opportunities of study, that they are generally content to acquiesce in the opinion of any one who may expressly devote himself to a specialty which they may not have leisure to analyse properly, although their own experiences, as incidentally affecting the subject, may lead them to other and conflicting conclusions. The results of the system of proceeding generally adopted in the iron trade (at any rate until very recently) singularly illustrate the enfeebling action of this excessive division of labour, combined with this easy-going tolerance. An industnous unit of our utilitarian class, absorbed in ingenious contrivances for the economy of production and developement of strength, fibre, clean- casting, &c. of the metal, instead of troubling his head with the study of such general principles of composition as would lead him to combine and refine successfully upon the elements it is his specialty to deal with, sends straightway for one of our ideal class, and confides to him the charge of making what is called a design; believing that the artist, from his professing art, nmst of necessity be able to do it; and receiving as gospel anything that may be prettily sketched or prettily asserted concerning the specific ornamental form which may be superadded to make his simple objects look anything but what he originally intended them for. Not troubling his head much about this, he hugs himself in the consciousness that his part of the business is very well executed, and that as he has " got the oniameut done" by a crack, or at any rate glib artist, it is no doubt likely to do him great credit. Now, what, under the most favourable circumstances, is likely to be the result? The ideahst, overflowing with associations of beauty in marble or stone, in painting or in architecture, will be found to have lavished his pretty fancies just in the wrong place, and in a form often so unsnited for manufacture as to entail an utter sacrifice of what he relied on for effect before his design can be embodied iu practical form. Sometimes, alas ! he breaks down from being set to speak a language, with the grammar and component elements of which he is utterly unacquainted, and so falls back upon the dreary precedent of what somebody else has just been doing, or copies and fits in a bit of Jupiter Stator scroll, Louis Quatorze shell-work, or Gothic panelling, thinking that that will be quite safe. Had our ideahst but shaken off' the trammels of his lot in the division of labour, and dared to enter into the charmed circle in which he believes the utilitarian to be necessarily the sole potent enchanter, the spell that bound his energies might have been broken, and he, too, might have successfully aided in subduing all sorts of lucky sprites to work out successfully his own and his co-magician's will and bidding, and together and of one mind they might have wrought marvels. The lesson such experiences should teach is fit to be assumed as a corollary of the first importance, and is simply to the following effect : — No successful results can be attained in the production of beautiful iron- work, or beautiful anything else, mitU one of three things takes place, — either, first, until the manufacturer and designer are one individual doubly gifted ; or, secondly, until the manufacturer takes the pains to investigate and master so much of the elements of design as shall at least enable him to judiciously control the artist; or, thirdly, until the artist, by a careful study of the material and its manufacture, shall elaborate and employ a system of design in harmony with, and special to the peculiarities so evolved. It is quite true that the greatest w-orks in iron which have been executed of late years have been worked out by civil-engineers, and the minor, Init most fanciful ones, by architects ; but it is so difficult to define where civil-engineering ends and architecture begins, that in the few remarks we are about to make we shall employ the latter term to represent, in addition to its ordinary meaning, so mucli of the science of civil- engineering as is essential to general construction, or amenable to the terms of existing styles. Modern science having suggested iron as admirably adapted by its strength, elasticity, toughness, and durability for the purposes of construction, its introduction obviating many difficulties almost insuperable with- out it, and our necessity imperatively urging the adoption of a material possessing such qualities, uncongenial as it may appear to our previous notions of architectural taste, we have been compelled to place it on the THKORY. XV list of available building materials. It is due to the exertions, and to the necessity which stimulates the endeavours, of that class of architects which we have denominated the Utilitarian, to acknowledge that at the present time the science of the employment of iron In construction has reached a high degree of perfection ; — that not only have its toughness, elasticity, specific gravity, capabilities of compression, and almost every possible contingency of its use, been nicely calculated and recorded, but that modei'n science has even laid down, and invariably provides for, the proportions of its expansion and contraction, and devised and ex- perimentally proved the forms in which, with the minimum of metal, the maximum of strength is to be obtained. When, on the other hand, we enter upon an examination of what the influence of taste has effected, in overcoming the several difficulties pecuhar to the material, and to the natural disincUnation of the eye to appreciate change in what it has been accustomed to admire, — when we look at the monstrosities of form in every style of design issuing from the foundries, — not to be once used and then perhaps lost sight of in obscurity, but multiplied and perpetuated through the medium of casting, — thrust forward on all occasions as if in vain-glorious consciousness of their superlative violation of the laws of harmony and proportion, — we cannot but feel conscious that the steady course of utility has, at least in this instance, outstripped its more poetical associates, inventive genius and good taste. We have glanced at the difficulties of system that must be overcome before iron can be rendered a pleasing object to the eye of taste, but it is only by a rigid examination of these points of difficulty, in relation to the several existing styles of architecture, that we can hope to estimate them rightly, since, so long as the association of ideas prevents a sudden revolution in matters depending on " the education of the eye," it is in the orbit of those styles that our ideas will perpetually revolve. Our chmate, religion, and habits, are so utterly opposed to the introduction of either of the Egyptian or Indian styles, that they have merged rather into topics of curious inquiry for the antiquary than into subjects of important consideration to the practical architect. At this moment we are not enabled to remember more than two or three specimens of the former in the metropolis, — the Egyptian Hall, Piccadilly ; a house and shop-front in Welbeck Street ; and the entrance to the Abney Park Cemetery. Among the building designs in the Exhibition of Industry were two or three magnificent sarcophagi. In connexion with one of such buildings only have we seen iron introduced ; and there, in nice keeping with glazed sash-frames and hrown-hoUand blinds, have we seen a remarkably neat cast-iron railing, neatly painted, connecting the main masses of the "])ropylon." Such anomaUes must ever result when lightness, the peculiar characteristic of the employment of iron, is placed in juxtaposition to the grand solidity that characterises these styles, We now proceed to the pure, the chaste, the beautiful Greek ; and first, we would notice the extreme dependence of the classical styles upon association for effect. In the graceful combination of strength and ornament in Grecian architecture do we not strive to reahse to ourselves that union of mental vigour and elegant taste for art that so splendidly elevated Grecian intellectual power ? Do we not look upon the ruins of their temples as hallow'ed relics of the purest art? Do we not study and re-study their orders and proportions but to catch one spark of the genius that fired them i What, then, must be the feehngs of the enthusiast for Grecian architecture, when he sees (as here, and now, he could not fail to do) a cast-iron girder thrown across an opening, a Grecian entablature and Grecian ornament stuck upon its face, and not a semblance of a column in the whole composition — when he sees a cast-iron post, with a Greek anti-cap stuck upon its head, about twenty diameters high, and no entablature, supporting a massive pediment — when he sees (as he must in almost every street) the graceful honeysuckle of the Erechtheion, shrunk in the atrophy of cast-iron, decorating the areas and balconies of houses and buildings of every description of purpose and every gradation of ugliness — when he recognises the simply beautiful variations of the lotus ornament expanded into lamp-posts, here the unfitting decoration of a Christian church, there flaunting on the lamps, area- gratings, and bar-columns of a gin-shop? It would be diverging too much fi-om our course now to enter on the question of the propriety of the introduction of Grecian architecture to this country, but we cannot refrain from noting the fact, that, within the last few years, the popular enthusiasm for that style of art, kindled by the labours of Stuart, Revett, Major, and the Dilettanti Society, sustained by the energy of Wilkins, Cockerell, Donaldson. Angell, Leake, &c., has materially declined. We would account for this, very mainly, by the obtrusive dragging forward and XVI 'IMTEORY. multiplication of its most beautiful ornaments by means of cast-iron and cement. Whatever abstract beauty has existed, still exists in these decorations : yet as the most charming airs lose much of their once-stimulating effect when thrust upon the ear, out of all time and out of all place, through the medium of incessant street-organs, bands, and butcher-boys, so do these lovely ornaments lose their effect upon the eye when thrust forward and maltreated by cement, and doubly thrust forward and maltreated by cast-iron. Many of our remarks concerning the moulding of iron into the forms, proportion, and details of Grecian architecture, will apply in an almost equal sense to the peculiarities of the Roman style, regarded from a similar point of view ; with this exception, that in the general principles of design far greater latitude is allowable in this style than in the Grecian, and that in this, therefore, the judicious architect will meet with many more loopholes at which, with due judgment, his iron may be introduced, but subject always to at least these few points of caution, namely: — Never to imitate in iron ornament peculiarly identified with stone or marble; never to let his use of iron, either in girders, columns, bressumers, or roofs, interfere with the vital proportions of the order, its intercolumniation, or the pitch of the pediments ; never to construct in iron what may be better executed in any other material ; to recollect that a needless display of strength is just as weak as an appearance of deficiency, and that both excesses are to the educated eye almost equally objectionable ; and above all, never to make his iron-work obtrusive, or to use any ornament to repletion. " Within these limits there is 8])ace enough." It is a great mistake to imagine that a so-called "rich" cast-railing — a thing all spike, flower, standard, scroll, and dog-rail — will make a poor building, or one destitute of ornament, look handsomer ; like the beggar's cloak, it only draws attention the more readily to the poverty it almost invariably fails to conceal. Another fertile source of unpleasing effect is the habit of taking away an essential component part of any order, and using it in a situation in which it does not fulfil the purpose for which it was originally intended ; — such, for instance, as the introduction on the face of an iron bressumer of the entablature of one of the orders, without a symptom of the columns, its legitimate, invariable companions ; the use of a shaft for a lamp-post, with as few symptoms of an entablature; or the bringing down of the dignified Greek Doric column to the situation of cast^ron baluster to a staircase or balcony — vide the British Museum, and London, passim. Sufficient instances of the various ''perils that environ the men who meddle with cold iron" have now, we imagine, even in these two styles, been brought forward to develope the truth of our assertion, that the present state of design, as applied to iron, in connexion with existing styles, is in a low condition, and apparently not conducted upon right, or, indeed, upon any fixed principles ; and if, moreover, on a careful comparison of them with our own individual experiences, it should be found that improvement in the artistic treatment of the material within the last few years has been by no means adequate to the increase in its consumption, a more extended apphcation of such material cannot, unless a radical change take place, but prove detrimental to the general progress and improvement of design in other substances. In approaching the subject of iron-work in connexion with Pointed architecture, we feel so strongly the excellence of Mr. Pugiu's observations, in the " True Principles of Christian Architecture," that wc do not hesitate to reproduce them, as expressing the soundest possible judgment and criticism : — " We now come," observes Mr. Pugin, " to the consideration of works in metal ; and I shall be able to show that the same principles of suiting the design to the material, and decorating construction, were strictly adhered to by the artists of the middle ages in all their productions in metal, whether precious or common. " In the first place, hinges, locks, bolts, nails. Sec, which are always concealed in modern designs, were rendered in Pointed architecture rich and beautiful decorations ; and this not only in the doors and fittings of buildings, but in cabinets and small articles of furniture. " The early hinges covered the whole face of the doors with varied and flowing scroll-w^ork. Of this description are those of Notre Dame at Paris, St. Elizabeth's Church at Marburg, the western doors of Lichfield Cathedral, the Chapter House at York, and hundreds of other churches, both in England and on the Continent. Hinges of this kind are not only beautiful in design, but they are practically good. We all know that, on the principle of a lever, a door may be easily torn off its modern hinges by a THEORY, strain applied at its outward edge. This could not be the case with the ancient hinges, which extended the whole width of the door, and were bolted through in various places. In barn-doors and gates these hinges are still used, although devoid of any elegance of form ; but they have been most religiously banished from public edifices as unsightly, merely on account of our present race of artists not exercising the same ingenuity as those of ancient times, in rendermg the useful a vehicle for the beautiful. The same remarks will apply to locks that are now concealed and let into the styles of doors, which are often more than half cut away to receive them. A lock was a subject on which the ancient smiths delighted to exercise the utmost resources of their art. The locks of chests were generally of a most elaborate and beautifiil description. A splendid example of an old lock still remains at Beddington Manor House, Surrey, and is engraved in ' Pugin's Examples.' In churches we not unfrequently find locks adorned with sacred subjects chased on them, with the most ingenious mechanical contrivances for concealing the key-hole. Keys were also highly ornamented with appropriate decorations referring to the locks to w^hich they belonged; and even the wards turned into beautiful devices and initial letters. " In all the ancient ornamental iron-work we may discern a peculiar manner of execution, admirably suited to the material, and quite distinct from that of stone or wood. For instance, tracery was produced by different thicknesses of pierced plates laid over each other. Leaves and crockets were not carved or modelled and then cast, but cut out of thin metal plate and twisted up with pUers, and the lines or stems either engraved or soldered on. By these simple means all the lightness, ease, and sharpness of real vegetation is produced at a much less cost than the heavy fiat foliage usually cast and chased up. It is likewise to be remarked, that the necessary fastenings for iron-work were always shown and ornamented. Bolts, nails, and rivets, so far from being unsightly, are beautiful studs and busy enrichments if properly treated. Large tracery was either formed of round iron, like a stem twisted into intersections, or of fiat iron bars of different thicknesses riveted together, and the edges chamfered by filing. Railings were not casts of meagre stone tracery, but elegant combinations of metal bars, adjusted with due regard to strength and resistance. The fire-dogs, or andirons, as they were called, which supported either the fuel-logs where wood was burnt, or grates for coal, were frequently of splendid design. The ornaments were generally heraldic, and it was not unusual to work the finer parts in brass for relief of colour and richness of effect. These form a striking contrast with the inconsistencies of modern grates, which are not unfrequently made to represent diminutive fronts of castellated or ecclesiastical buildings, with turrets, loopholes, windows, and doorways, — all in a space of forty inches. The fender is a sort of embattled parapet, with a lodge - gate at each end ; the end of the poker is a sharp-pointed finial, and at the summit of the tongs is a saint. It is impossible to enumerate half the absurdities of modern metal-workers ; but all these proceed from the false notion of disguising, instead of beautifying, articles of utility. How many objects of ordinary use are rendered monstrous and ridiculous, simply because the artist, instead of seeking the most convenient form, and then decorating it, has embodied some extravagance to conceal the real purpose for which the article has been made. If a clock is required, it is not unusual to cast a Roman warrior in a flying chariot, round one of the wheels of which, on close inspection, the hours may be descried ; or the whole front of a cathedral church reduced to a few inches in height, with the clock-face occupying the position of a magnificent rose window. Surely the inventor of this patent clock-face could never have reflected that, according to the scale on which the edifice was reduced, his clock would be about 200 feet in circumference, and that such a monster of a dial would crush the proportions of almost any building that could be raised. But this is nothing when compared to what we see continually produced from those inexhaustible mines of bad taste, Birmingham and Sheffield. Staircase turrets for inkstands, monumental crosses for light-shades, gable-ends hung on handles for door-porters, and four doorways and a cluster of pillars to support a French lamp ; while a pair of pinnacles supporting an arch is called a Gothic -pattern scraper, and a wiry compound of quatrefoils and fan-tracery an abbey garden- seat. Neither relative scale, form, purpose, nor unity of style, is ever considered by those who design these abominations ; if they only introduce a quatrefoil or an acute arch, be the outline and style of the article ever so modern and debased, it is at once denominated and sold as Gothic." Any observations we could offer upon our subject in connexion with Gothic architecture, would but be superfluous ; yet we cannot refi-ain fi'om bearing a humble tribute to the truth and justice of many of Mr. Pugin's propositions. The other day, in one of the modern churches, our eye was arrested and our attention TIJKORY. distracted bj noticing the substitution of iron for stone piers to divide the nave and aisles ; they were, of course, kept thin to faciUtate the view of the preacher and east end; their effect, consequently, to the eye of any person accustomed to the ordinary rules of ancient proportion, would be that of inadequacy to support the superincumbent weight; strongly reminding one of spindle-shanks, — mightily suggestive of Gothic in a consumption ! It is the more melancholy that such defects should commonly exist in modern attempts to connect iron-work with Pointed architecture, since it is in the medieval examples of processes and handicraft that we meet with the highest triumphs of the smith's art. In such compositions as the well at Antwerp, the enclosures of Henry VII. 's, Edward IV. 's and Queen Eleanor's tombs, the beautiful doorways of Ely and Rouen Cathedrals, the hinges of Lincoln Cathedral, St. George's Chapel, Merton College, Sec, we meet with specimens easily referred to, and which, if rightly studied, should convey to us tacit lessons, which, con- scientiously acted up to, would lead with certainty to the legitimate treatment of Gothic iron-work at once in point of general form, and in all the refined detail of fabrication. Among the happiest specimens we have seen of revived medieval iron-work of a simple kind, is the railing surrounding a tomb which has lately been erected in Rochester Cathedral. In the smaller objects of eccle- siastical use, Mr. Potter, the protege of the Cambridge Camden Society, has produced some creditable works ; but in that particular branch, as in many others, Mr. Hardman of Birmingham reigns supreme — facile princpps. As the styles of national architecture approach our own time more nearly, inconsistencies in the employment of iron become less apparent ; and although in connexion with the classically Italian styles of Palladio and his contemporaries, the architect is in danger of some of the stumbling-blocks we have connected with Grecian and Roman art, yet in the style of the period when Italian forms and details were engrafted upon our habitual domestic modes of construction, we have more nearly approached success than in most of our other endeavours to wed the dtdce with the utile. Specimens of the happiest treatment and execution of iron grilles and gates may be met with in the rich and flowing lines of scrolls and flowers worked in wrought-iron, decorating the entrances to many buildings of the days of Queen Anne and the two first Georges, — evincing no ambitious assumption of the main features of the style it decorated; — not stealing here a moulding from stone, and there an ornament from wood, all bedaubed with a green and copper imitation of bronze, but exhibiting the proper and distinctive treatment of a subservient material ornamenting buildings, with the architectural character of which it assimilates, yet does not interfere. Many specimens of this elegant style of railing, &c., about the odd and quaint habitations of our old English gentlemen, and more especially at Hampton Court, Oxford, and Hampstead, still attest the surprising dexterity of the smiths they must have employed. With some modifications this style may be said to have predominated from the reign of Elizabeth to the end of that of George II. From considering our progress in aping effete conventionalities let us turn to the origination wc may be said to have given to the developenient of new styles dependent on the imperative requirements and giant mould of modern civil engineering. We shall there find the " Lamp of Power " shining over all, while the "Lamp of Beauty" occasionally lends its purer, happier ray, at least partially, to illumhiate the objects with which it is brought into contact. In those wonders of the world, the Menai and Conway Bridges, the simple and severe fines of the archi- tecture happily accord with the lofty simplicity of thought, which would have evaporated had the frivolities of ornament been applied to it. In the High Level Bridge, at Newcastle, Mr. Stephenson has succeeded in uniting grandeur of line with absolute perfection of scientific contrivances and economy of material. In tlie Hungerford Suspension Bridge, and in many of his other works, Mr. Brunei has shown that Ms inde- pendence of meretricious and adventitious ornament is as great, and as above prejudice, as his engineering works are daring in conception and masterly in execution. From such beginnings as these and the Crystal Palace, with its revival at Sydenham, what future glories may be in reserve,— when England shall have systematised a scale of form and proportion— a vocabulary of its own in which to speak to the world the language of its power, and its freedom of thought and feeling— we may trust ourselves to dream, but we dare not predict. Whatever the result may be, it is impossible to disregard the fact that the building for the THEORY. XIX Exhibition of 1851 is liliely to accelerate tlie "consummation so devoutly to be wished," and that the novelty of its forms and details will be likely to exercise a powerful influence upon national taste. In the design of the thousand-and-one miscellaneous objects which may be included in the term "fancy castings," the English have made considerable progress of late years; and we trust that as the practice of ornamental modelling becomes more universal among the workmen, they may soon rival the delicate foliage and handling of ornament which have rendered the French masters so celebrated. In the railing executed for Mr. Hope's mansion in Piccadilly the English manufacturer has an opportunity, without going far from home, of realising to himself the peculiar excellencies to which we allude. In it he will also recognise, if we mistake not, a superiority rather of hand than of head, a fertility of fancy rather than a refined perception of combination of line, or purity of form, an illustration of the practice of scribbling in the ornament without the revision necessary to bring the lines and proportions into proper harmony. The somewhat bungling stilting of the capital will suffice to illustrate our meaning It is, however, a specimen, the beauties of which are far more conspicuous than the faults, and it would be well if there were many such in London to criticise. To tlie exertions made by the Coalbrookdale Company to elevate the character of the design of fancy castings too much praise cannot be given. The efforts they have made to elevate iron into a material for e.vpressing the loftiest order of fine art, and the spirit with which they have enlisted the highest sculpturesque abihty redound to their credit. No reflecting person can give a thought to the subject without perceiving that English formative art is changing in its conditions almost from hour to hour, that there is a spirit of impulse abroad striving to effect reform, without revolution, in the science of design as in politics, and that an evil instead of a " good time is coming" for those who may choose to long "stare super antiquas vias." What may he the ultimatum reached by iron, and how far its treatment may achieve approximate perfection in our time, is a problem none can solve. Schools of design may certainly do something, commercial spirit and energy much more, cultivation on the part of the public the most; how these have been acting lately the Exhibition of 1851 has shown. We can only now express a hope that men of genius will throw off their apathy, will con- descend to give their best attention to that which sooner or later must become an all-important bianch of the profession of design, and so elevate their treatment of this material, that our grandchildren and great-grandchildren may not look back upon us, their progenitors, as unworthy sons of this most essentially fetrea tetas. We shall proceed to offer a few remarks on, — BRONZE -WORK, AND THE PRINCIPLES OF ITS TREATMENT. From the earliest ages of the formation of the alloy bronze has been constantly adopted as the material best suited to convey severe sculpturesque expression. It is from a careful examination of the works of the ancients that the student is best enabled to recognise the principles upon which compositions intended for reproduction in this material should be based. He will at once find that striking differences of proportion manifest themselves between statues executed in marble and those of which bronze forms the material. In consequence of the dark colour of the latter, every portion of the form, in order to be clearly defined, requires a certain amount of conventional treatment ; so to increase the sharpness and precision of the several forms and markings, as to enable the spectator to appreciate them at that point of view, from which he may likewise take in the general outline, upon which the effect of the whole figure depends. A comparison of the Greek specimens of bronze-work with those of Verrocchio and Donatello, will at once illustrate the precise pohits of exaggeration, by means of which great solidity of shadow was invariably attained. The light being supposed in every case to descend from above, the under surface of eveiy projection intended to throw a shadow upon the surface beneath, was always hollowed upwards, and brought to a fine edge only at its extremity. Thus the eyebrow was marked as a sharp line, and the eyes sunk, as it were, in hollow sockets ; increasing the depth of the tint of shadow cast by the eyebrow, by turning away from it those surfaces likely to receive the light reflected from the cheek, nose, or other adjacent illuminated portions XX THEORY. of the head. The nostrils were likewise brought to sharp edges ; the mouth, at the junction of the lips, was cut upwards into curious cavities ; and a close examination of the w hole form of the head would serve to show that, in every part, the artist was guided in his modelling by a consummate knowledge of the means necessary to compensate for and overcome the optical difficulties attaching to the material in which he worked. One important element in determining the precise form of a bronze statue will be found to be a consideration of the background against which it must be relieved. Where that is light, as when the statue is brought against the sky, greater fulness must be given to the proportions of the limbs ; since, from its superior power, the light is apt apparently to invade, and, consequently, diminish the silhouette. Where, on the other hand, the figure is thrown up from a niche, or from a dark background, a contrary system of proportion should be adopted, to restrain the lighter-coloured substance of the statue from appearing to swell on to its darker ground. Another very important consideration in designing works of art of a higli class in bronze is that of the varying points of view from which the object may be examined ; for, as the effect of any statue in so dark- coloured a material must mainly depend upon its contour, care must be taken that that contour be clearly marked, and not liable to confusion, from such an arrangement of the parts of the figure as would permit any one of them to be awkwardly lost or merged in another. Hence those attitudes in which the figure approaches the condition generally known to heralds as " displayed," are best adapted for execution in this material. The celebrated Mercury of John of Bologna, to which we have already referred, is, perhaps, the happiest existing instance of such a mode of treatment. In important equestrian figures we too frequently have occasion to regret that a style of costume is adopted which, when the statue is viewed from such a distance that the spectator cannot appreciate its precise form, tends to convey the uncomfortable impression that the body which it serves to clothe has swollen to the dimensions of the flowing garments. In sculpture it is no doubt an extremely difficult task to provide, in all cases, against the risk of this confusion of parts ; but if attention to this point is important in works executed in a material like marble, the pure colour of which shows, at a great distance, the minutest variations and sinuosities of form and plane, how much more so must it be when a material like bronze is used ; in which the eye is misled, not only by its want of power to distinguish forms in a material of so deep a colour, but by the varying lights and uncertain reflexes of its metallic surface. It may be assumed, therefore, that in all large w^orks in bronze extreme simplicity is an indispensable requisite. When, however, the skill of the artist is exercised upon objects of a small scale, this attention to simplicity is no longer so cogent a necessity. In cabinet specimens, destined for close inspection, the workers in bronze should take advantage of every refinement of execution calculated to heighten the eff'ect and texture of the object he is called upon to produce. For this purpose he will do well to examine with attention the respective styles of the two great Italian schools of bronze-work, — the earlier, or soft style, represented by the works of Ghiberti, Luca della Robbia, and Sansovino ; and the later, or bold style, by those of Donatello, Verrocchio, and PoUaiuolo, and ultimately of the great Michael himself. In the former of these styles he will find an attempt to express, by comparatively direct imitation, every variation of form existing in nature. The exact quality of the object intended to be imitated is recalled to mind by an abundant use of the graver and chasing-tool, and by a sedulous endeavour to vary the texture and roundness of every portion of the flesh or drapery. This style of positive imitation, it will be found, is redeemed from frivolity and feebleness by an intense appreciation of beauty of line on the part of those who practised it. The artificial nature of the composition redeems the too natural style of the treatment; and the power of the artist is revealed in his exquisite appreciation of grace and beauty. In examining the works of the latter school the student will perceive, on the other hand, that the aim of the sculptor was rather to convey a vigorous general expression, — some strong and palpal)le emotion. With this end in view, he has avoided dallying with the graces of the several parts of his composition, and has sought only to combine them into one forcible whole. Hence, in the details of the treatment, the graver, chasing-tool, burnisher and point, are no longer used to indicate each particular hair, and every minutia of form ; but punches, files, hammers, and pi iers, have conduced to the production of forms, which, aUhough they seem rude and careless on a close inspection, fall at once into their appropriate places -when examined from the proper point of view, and fitly contribute to the general effect of the work. It would be unjust to extol either of these schools to the disparagement of the other : it would be alike THEORY. XXI unwise to recommentl to the student ton great a reverence for Donatello, or too great a love for Ghiberti. "We would rather have him take into consideration, without prejudice, how far a leaning to either style of execution may best accord with the nature of the subject upon which his own ability is to be exercised. The rude vigour of PoUaiuolo would as little comport with the treatment of a Venus, a Psyche, or a Seraph, on a small scale, as would the softness of Ghiberti with the awful grandeur of a colossal Jove or an enraged Achilles. It has been justly remarked, both by M. Quatremere de Quincy and by Sir Charles Eastlake, that, in the execution of sculpture, care must be particularly taken that those portions of the work which represent objects in reality of the same material as that in which they are represented, should be treated in a manner so obviously conventional as at once to undeceive the spectator as to the possibility of their actually being what they represent, instead of mere imitations. This rule is particularly to be observed in the imitation of metal- work. The details of armour and harness are frequently dwelt upon with such a degree of elaboration, as to make us regret that the sculptor had not obtained, from a better manufacturer, an actual suit of the former, or set of the latter. The just principles of designing small works in bronze have been peculiarly studied by our French con- temporaries, and have been carried by them in many instances to a very high pitch of perfection. Few have done more in France, of late years, in contributing to a recognition of the dignity of the material, than Henri de Triqueti, whose elaborate gates to the Madeleine are among tlie finest bronze works which have been ever executed. It is much to be regretted that in England few living artists have specially devoted themselves either to the practice of the mechanical process of bronze-founding, or to the study of the best conditions of its design. It is true that, from time to time, very many large and important works are modelled and cast with considerable ability in foundries in various parts of the kingdom ; but it would be diificult to believe that any of them have been expressly intended for execution in metal. We have, at all events, been unable to trace in them any distinction between the conventionalities employed, and those which the same artists would pro- bably have used in the execution of the same subjects in stone or marble. We firmly believe that the ancient sculptors adopted a completely different system of modelling for each of these materials, and regarded their respective capabilities in a just and proper light ; never executing in bronze subjects better adapted for marble, nor in marble those better suited for bronze. Mr. Hatfield has recently done much to improve the manipulation of the art of bronze-casting and colouring; and it is to be hoped that, at no distant day, we may be fortunate enough to create a national manufacture of objects in this beautiful material. So soon as a taste for bronze statuettes shall become at all general in this country, the public will at once perceive the nature of the conventionalities necessary to be resorted to in such compositions, and their awakened taste will so far react upon artistic education as to lead to efforts which, if not more vigorous, may at least be more loftily directed. GOLD-WORK, AND THE PRINCIPLES OF ITS TREATMENT. We can imaghie few lessons which would prove of greater advantage to the jeweller of the present day than a careful study of the exquisite specimens of ancient art, which are preserved in the Etruscan Museums of Pope Gregory XVI. and the Cavaliere Campana of Rome. In those collections he would find works adapted for personal decoration, of the most exquisite design, and executed by the simplest processes. Ih some of the beautiful golden garlands, which the ladies of Etruria were wont to bind around their brows, he would at once perceive how s kilfull y an idea borrowed directly from nature — that of entwining together a simple group of leaves and flowers — may be carried out, witliout in any degree infi-inging upon the conven- tionalities proper to the material employed. He would see collars, upon portions of which the most exquisite patterns are defined by filagree, disposed in graceful curves and scrolls, and soldered to the sheets of gold forming the substance of the work. The edges he would find bound witli a twisted wire, to give strength to the whole, and enriched with small and beautiful pendants, hanging fi-om them like a precious fringe. If it were possible to place by the side of such specimens some of those heavy bracelets, simulating uncomfortable snakes or ponderous fetters, and earrings decorated with unmeaning shellwork, which abound in the shops of the modern jeweller, it would be impossible to avoid the conclusion that if the mechanical facihfies of production are perfectly comprehended in the present day, an almost total ignorance of the just xxii TIIIiORY. principles of special design is no less genei'ally prevalent. Wlien we reflect on the extreme beauty of gold, on its great value, and on its association in our ideas with all that is most rich and brilliant, it is the more to be regretted that art is so rarely allied to manufacture in its elaboration. It appears as if the old ideas of barbaric magnificence still cling to its use — that while in bronze and in the baser metals the artist feels deeply (or, at least, acknowledges) the responsibilities of his profession, in gold any style of form is admissible, and that a multitude of sins are covered by the brilliancy of sparkling jewels and the value of the metal which surrounds them. It is most remarkable that while sums of almost any amount, determined only by the caprice or fashion of the day, are constantly given for diamonds and other precious stones, the nature of their setting should receive so small an amount of attention. It would indeed be a triumph of art so to elaborate the precious metal surrounding the diamond as to make the frame more beautiful than the picture it contains. .But whilst we urge this deficiency in much of the modern design apphed to jewellery, let it not be imagined that we could regard as any improvement a reduction of the large designs which find iitting expression in marble or in bronze, to the miniature proportions in which gold must generally be worked. It is ever to be remembered that jewellery, after all, is but a personal adornment, and that if, by imitative art, any animated objects are represented in it, they shoidd take the form rather of concetti than of serious compositions. The world-wide celebrity of the Italian school of goldsmiths is due to the taste with which Cellini, Caradosso, and other masters, enriched the jewels of the Cinque-cento age with the most exquisite lamri tli mhmteria. Un- fortunately, too few relics of that school exist, and it is rather by tradition than by actual evidence that we can fully appreciate all its beauties. The study, however, of such works as time has spared, and of such drawings or designs as are still in existence, has unquestionably stimulated the French jewellers of the present day in the production of many very beantifnl modifications of the media>val and Cinque-cento styles. MM. Froment-Meurice, Rudolphi, and Morel, have in this way produced many works which deserve the highest commendation; and it was gratifying to observe in the specimens contributed to the Great Exhibition by Messrs. Garrard, and Hunt and Roskell, that their attention had been directed to similar sources of design. A careful examination of the elaborate paintings of our ancestors, by Sir Antonio More, Zucchero, Holbein, and even Vandyck, will afford many illustrations of the beauty of design of much of the ancient jewellery of this country. It is too much to be feared that, in the productions of modern portrait-painters, our descendants may seek in vain for any equivalent to the beautiful goldsmith's work of former days. The very limited use of enamel in connexion with jewellery is greatly to be regretted; since the elegant works of Cellini, and indeed of every great master of the goldsmith's art, have been greatly indebted to that substance for pleasing and appropriate decoration. We venture to hope that the details, which it is our intention to give in subsequent pages, of the processes employed in the several varieties of ancient enamel, may tend in some degree to a recognition of the importance of this elegant adjunct to the splendour of rich metal-work. The unwillingness of modern artists to regard enamel otherwise than as a vehicle for pictorial representation, is perhaps in some degree to be ascribed to the extent to which the system of the division of labour has been carried in this economic age. Had the labours of our enamel-painters been associated with those of practical manufacturers, there can be no doubt that the specimens of EngUsh jewellery, in the Great Exhibition of 1851, would have occupied a yet higher position than they did on that occasion. Much as we must admire the works of such artists as Mr. Bone and Mr. Essex, we cannot but regret that their attention has not been directed to the union of their beautiful art with that of the goldsmith. Their style, based on the practice of their great predecessors, Petitot, BortUer, Zinck, Hance, Gueraier, Moser, Meyer, &c., is confined to painting only, and not extended to manufacture. Could we but see a little of their accomplished abUity brought to bear vipon the revival of some of the ancient systems, such as the " grisaille " of Limoges, a portion of their grace imparted to the handicraft of the common workman, we might then have great hopes, that while novelty was sure to arise it would not be vulgarised by betraying the want of education of Its origmators, and that while the intelhgence and intellectuahty of the workman would be stimulated, the public would ultimately gather "a ripe and golden harvest." As the Abbe Texier tells us, in a passage of extreme eloquence, "in the middle ages, art and manufactures were blended and identified; art gained by this affinity great practical facility, and manufacture much original beauty." THEORY. SILVER -WOKK, AND THE PRINCIPLES OF ITS TREATMENT. There are few subjects on which we entertain more sanguine hopes than that the beneficial effects of the Great Exhibition will be very speedily manifested in the improvement of the ordinary forms and types of modern English works in silver. In those important pieces of plate on which such large sums of money are annually expended, we have been too long accustomed to content ourselves with reducing, to some foot or two in height, a great allegorical monument, such as those which desecrate, rather than decorate, the sacred fanes of Westminister Abbey and St. Paul's. In silver, as in marble, we have been too long satisfied with personations of Virtues and Graces, Arts and Sciences, disposed around a statue of the individual to whom the so-called " testimonial" is presented. Fortunately, we are now beginning to perceive that something better may be done, and that at the additional expense only of a little more thought and study. It is justly remarked by Mr. Redgrave in his " Report on Design," appended to the General Reports of the Juries of the Great Exhibition,* that " if we contemplate some of the inventions of the artists, and some of the thoughts which they have wrought out, we shall be indeed surprised that such puerilities could be dwelt on long enough to execute them as works of art, and still more that manufacturers, so shrewd as they generally are, should be found to engage in their production, were it not sufficiently evident that there is a large and wealthy public whose taste does not rise above such art, proved by its becoming patrons and purchasers. What can justify the employment of the precious metals, and what ought to be the more precious labours of artists, upon huntsmen and ploughboys, to render them with all the coarseness of their garments and the texture of their hose ? or who but the givers of a testimonial, relying on the known taste of its receiver, would require art to be degraded into the mere imitation of a hedge-row occurrence on a hunting-day when the sport was successful ; knee- breeches and top-boots being as important items in the groups as the hounds, horses, and the portraits of the individuals whose good fellowship it commemorates ? It is such art in the more precious metals, employed on such thoughts, that leads, in the imitative manufactures, to the many paltry inventions which are found to prevail therein. Rachel at a well in a rock, under an imitative palm-tree, draws — not water, but ink : Burns' shepherdess would find the same black fluid in the formless well by her side ; a grotto of oyster-shells with children beside it, contains, not a light, but an ink-vessel; the milk-pail on a maiden's head contains, not goat's milk, as the animal by her side would lead you to suppose, but a taper. Such works are akin to epergnes with the hippopotamus and his keeper ; or Paul and Virginia under a palm-tree that upholds the glass for flowers on its top ; or Apollo dancing, supporting at the same time a glass cpergne twice his own size ; and inventions of equal or greater novelty wrought out with great waste of skill and labour. Even when we arrive at really artistic works in this style, of which happily there are many, it is more than doubtful whether the omamentist would not be more suitably employed upon them, and an ornamental and architectural construction first obtained, before art w^as called in to aid in their completion. It is not pleasant to add, that the above strictures more especially refer to English productions. It is true that such works have often a local significance or an individual importance, causing their exhibition here, and making it less likely such should be exhibited by the foreigner than plate of a specific use, or ornamental works whose characteristics are more general ; but it is impossible to deny that the taste of the class who purchase or commission these works abroad must be higher than our own. *' In France, for instance, we find testimonials and prizes taking the shape of art rather than of massive metal. The President of the Republic, in contributing a prize to the winner of the Chantilly races, presents a shield, on which are four reliefs, illustrating racing in various ages of the world ; and when the worJcmeit of Montlucon and the inhabitants of Lot desire severally to present testimonials to Generals Changarnier and Cavaignac, the weight of silver is of far less importance in their eyes than the rare beauty of the art- workmanship. These works are exhibited by M. Froment-Meurice ; and the tw^o latter — two beautiful swords — are choice examples of design and chasing. Moreover, it is worthy of notice that in such works the artist does not consider his vocation a separate one, but regards the utility while he perfects the art. In both the above sword-hilts, the ornament (a group of figures) has been so thoroughly adapted and composed for its purpose as a handle, that it is perfectly accommodated to the grasp ; which is the case also with a beautiful short sword, ornamented * Page 737. xxiv THEORY. with the history of St. Hubert, executed by M. Marcel, and exhibited Ity Marrel Brothers (France, 331) in the same department." When we recollect the pecuhar properties of the precious metals — their strength and ductility — it must be at onee apparent that details of execution can be rendered in them, which could never be expressed in materials such as marble or wood. Hence, when we seek to elevate, to its highest perfection, technical execution in gold and silver, we must at once perceive that a new field is opened for the sculptor's art. By means of sft^vers and chasing-tools; and, by the process of repousse, which admits of a constant variation of relief, and the correction of redundant form, an amount of finish can be given to subjects of an eminently sculpturesque character, such as could not be imparted to tliem when executed by any other method. In the best ages of the goldsmith's art, this minute execution was carried to great perfection. By the Greeks, by the Italians of the Cinque-cento age, by the modern French; and especially by that exquisite artist, M. Vechte, refinements of texture and manipulation have been practised, which confer on objects executed in silver an eminently peculiar and distinctive cliaractei". It is one of tlie agreeable features of this process that the metal can be used in the greatest degree of tenuity. While its effect in that state is even better than it could have been had the metal been more substantial, and while the art is more excellent, the cost of the whole is so far reduced that it becomes a question, the solution of which scarcely admits of a doubt, whether the nature of the material should not be entirely disregarded, and the whole value of the object made to depend upon the art which may be lavished upon it. One cause of the defects in our productions in the precious metals may probably be the reluctance of our artists to study practically as workmen. Too many of those employed to design for silversmiths accept the commission only as a means of pecuniary support ; firmly believing that such employment is, in some degree, a derogation from that abstract condition to which, from want of education, or capacity to apply art rightly, they would seek to reduce it. Mr. Redgrave wisely remarks, " The truth seems to be, that in England one artist designs, and perhaps makes the model, whilst another is employed to produce it in the metal. Thus we find works designed with great ability, and modelled with much knowledge, and evidently by artists of great professional excellence, yet these works are completed in the metal with every possible littleness of imitation, serving only to degrade and vulgarise the art it is employed upon ; and this frequently is caused by the surface treatment and the mode of execution, wherein imitation has taken the place of art. Thus the true artist does not produce the texture of the fur of animals hair by hair, but gives its general expression by some conventional rendering, by the indications at the parts where the skin folds, or by tooling to emulate the lustre of its gloss. In the same way true art does not imitate the materials of our dress by the threads of its manufacture, but indicates them rather by the shape and contour of the foldings. Yet in the works under examination, the surface is often subjected by the workman to a most laboured treatment, labour without knowledge, which dwells more upon hairs and threads, upon details and buttons, than on the form of a joint, or the bones of an extremity : the one is a labour that requires no exercise of thought, nothing but mere dexterity ; the other requires a workman not only educated into a knowledge of the parts, but who can enter into the feeling and intentions of the designer. This dwelling with complacency on mere labour, and evident satisfaction with its tedious felicities, can only arise from tlie habit of giving the models of tlie superior artist into less skilful hands, to be completed in metal." One of the most fertile sources of the disagreeable effect in many compositions of the silversmith's art is to be found in a neglect of the consistent arrangement of the structural lines, which form, as it were, the building up of the design. By a perversion of that beautiful quality of strength in tentiity peculiar to metal, we too often find the stalk of a flower, or some such feeble object, called upon to do duty as a support to a vase, or other heavy object, beneath which, if real, it would inevitably break down. A combination of vine- leaves, with no trellis to sustain them, serves to sustain a ponderous wine-cooler ; and thus neither is the strength of the metal fitly represented, nor is any association of idea connected with the character of the ornament imitated in any way preserved. In a paper read to the Society of Arts, being " An Attempt to define the Principles which should determine Foi 'm in the Decorative Arts," we have entered at some length into the general principles of imitation and its restriction, upon which the special laws of design (in silver as in other objects) are dependent : it will not, THEORY. XXV therefore, be necessary to enter in this place into a minute examination of the limits to which imitation may be carried in that material. We may, however, draw attention to two or three hidispensable requisites to a good design for silversmith's work. In the first place, the object must be so formed as to fulfil the purpose for which it is intended; — that object must in no way be disguised, but, on the contrary, should be apparent on the first cursory inspection ; — the general outline should be symmetrical, and the disposition of the various parts so proportioned as to appear strong, and equal to the constructive duties they may be called upon to perform;— the amount of ornament should be proportioned to the purpose of the object, and the means and condition of its proprietor; — there should be no direct imitation of Nature, and yet no perversion of her forms ; and lastly, it "would be well if a system of judicious contrast of plane surfaces and enrichment were carried throughout such works, and each ornament applied only to those points where the general form appears to demand accentuation. In productions in silver, as in every other material, there are a certain series of conventionalities to be observed and general conditions to be attended to, -which cannot be conveyed within the limits of a treatise like the present, but which must rather be acquired by long, laborious, and persevering investigation, by the repeated experiments, and frequent disappointments, of the student. It is only by the accumulation of the observations of tbose who have thus become masters of their art, by the record of their varied practice, and by an analysis of their system of treatment, that a grammar of the special design, proper and appropriate to metal-work, can ever be arrived at. At present we are ourselves rather in the position of a fellow-student inviting to learn, than a professor engaging to teach. Let it ever be remembered by the practical artist that, while it is impossible too highly to sublimate the ideal portion of his art, it is through material form alone that he can convey to his fellow-men the glowing creations of his imagination. Thus he has a double end to perform: to be at once subject ^to the conditions of the materials in which he works, and master of the art of struggling with their difficulties, and enhancing their beauties, so far as to dignify at once the material and the immaterial portions of his labour. To fitly carry out this object, his studies and his powers should be alike extended and yet concentrated. "When we bend our thoughts to a contemplation of the genius, taste, and delicate refinement of Visscher, Celhni, D'Arphes, Sansovino, Ghiberti, and many other artists, — when we realize to ourselves their industry and patience as mechanics, and their judgment, experience, knowledge, and energy as artists, we cannot but feel that to produce works approaching, far more excelling, those which have been executed in the past, quaUties of the most varied kind must be united. Let the student of design but make the endeavour to combine these in his own person— let him but struggle to add to a refined appreciation of the highest objects of his art a thorough mastery over the immediate processes of manufacture, and the joint production of his hand, eye, mind, and soul, will then bear the true and nnmistakeable mint-mark of pure and beautiful individuality. On the extreme value to the artist of earnest inquiry into the intellectual and mechanical conditions of the objects on the proper design of which he would exercise the godlike gift of genius, there can be only one opinion : and we cannot do better than conclude our remarks in the words of Lord Bacon, who points, as the true source of novelty, to the fact, that " from the knowdedge of physical causes there cannot fail to follow many indications and designations of new particulars, if men in their speculation will keep one eye upon use and practice." PRACTICE. GENERAL PRINCIPLES. The uictallurgic art commences with the extraction from the ores of those precious substances which, as metals, have played so important a pait in the civilisation of the world; but as the artist's connexion with them commences only when they are delivered to him in a state fit for working, we shall not enter into the details of any of the methods employed to free them from impm'ities, or, in other words, to bring them into the condition in which he receives them. We shall, therefore, assume the iron- worker to be supplied with either pig or bar-iron, in bulk, sheet, or wire ; and the gold or silversmith to be equally well provided with materials. The student who desires information on these preliminary processes may very readily obtain it from numerous authors, who have given special attention to the scientific aspect of the subject. The first class of processes must obviously be the Foumative, — those by which the raw material is converted into the object proposed ; and the second the Decorative, or those by means of which surface enrichment may be added. In oft'ering the following notices upon both groups of processes, wc must be understood as purposely avoiding mechanical or economical considerations, and noticing only such leading principles of either actual, extinct, or dormant practice, as may seem most likely to conduce to an elevation of the treatment of the metals, and a knowledge of which may assist the designer, by giving him command over the means through which his conceptions can best and most readily be carried out, and tlu'ough a subordination to which they can alone be made practical. Almost infinitely as the working details may be varied, the Formative processes in all metal-working depend only upon five systems, — Casting, beadnff cold, healing hot, electrotijpiiig , and cutting away hg abrasive tools. The degree in which these various systems should preponderate in the treatment of each metal must, of course, depend upon its nature and properties. All may be wrought by casting, but iron, bronze, and brass most successfully. Gold and silver, from theii- superior ductility, may be most readily fashioned in sheets by heating cold; iron by beating hot; electrofgping affects the pure metals; and all, pure or alloyed, reqnii'e in their finishing more or less cutting away of parts by abrasive tools. Of these four systems, in the present day, castinri is, perhaps, the most common and best understood ; and as many very excellent accounts of the ordinary processes of sand-casting, more particularly of iron, have been already published, we have devoted but few lines to that portion of the subject.* We have, however, treated more copiously those less-known variations in the practice of casting, by means of which works of art of the highest class have been, and are now, constantly executed. With regard to the system of heating cold, by means of which the finest works which have been wrought in silver have been produced en repousse, \ve have collected numerous illustrations of the practice of tlie best periods ; and from having enjoyed opportunities of seeing the greatest technic artist of the present day, M. Vechte, work, we know that the traditions of Cellini are not effete, and that the modem art-workman has nothing to do but to follow his precepts and succeed. With regard to the system of beating hot — the province more especially of the blacksmith — we have said but little, as the art is one principally involving manual dexterity, and because the principles of its practice are so generally apprehended, and have been recently so well described in detad by Mr. Holtzappfel. So many excellent manuals have been published on the subject of electrotyping, that we have given only the skeleton, as it were, of the process. With regard to cutting away by abrasive tools it will be unnecessary to say much, as everything must depend upon the well-trained haud of the artificer, working in obedience to a knowledge of art, and a fine appreciation of the exact effects attainable by a graduated manipulation of the respective metals. Thus the skilful chaser inay perceive that precise degree of refinement which might be admissible in silver, but which would be a petilesse in bronze ; but it \\ ould be difficult for language to define tools and handling which should vary with every respective occasion. It is to be regretted, that in the present day the Decorative processes of metal-working should be so much neglected in this country. Of the series we have enumerated scarcely one is now used ; and we have, therefore, endeavoured to be more explicit in our descriptions of them, — hoping that thereby some of the great manufactm'ers may he led to inquire for themselves, and ultimately to avail themselves commercially of the experiences recorded in those palmy days, wlicn exquisite metal-work, enamelled, parcel-gilt, or damascened, was looked upon as no less essential to the furnishing of a church or palace than the beautiful carving of the masonry, or the most elaborate interior decorations. In our remarks on these Decorative Arts we have translated freely from CeUini, whose exquisite works form the best possible testimonial to the inestimable value of his precepts ;+ and, as a general principle, have endeavoured to go into detail upon the least-known points of the subject, abridging to the narrowest limits our notices of processes for the examination of which the student is surrounded by opportunities on every side. • For a brief but moat lucid description of the nceeaaary arrangcmeMta of iron-casting, we would especially refer the reader to Mr. Holtzappfel'a excellent work on " Turning and Mechanical Manipulation," ^'ol. I. ■f We have even followed Cellini in hia numerous digiesaions, since they are not only eminently characteristic of the man, but, in many ca.se3, they help to elucidate the effects produced by the processea he describes. FORMATIVE PEOCESSES. I.— IRON-WORKING. Iron is usually worked into form by two operatious ; 1, by casting, — tliat is, rediu-ing the metal to a fluid state by means of lieat, and then pouring it into moulds, the cavities of which it fills, so as to constitute the couuterpart of the model by which the form of the cavities has been determined ; and, 2, by softening the metal by heat, and then beating it with hammers or punches into the requisite shape. In finishing up either cast or wrought-iron, files, chisels, gravers, and other cutting or abrasive tools, may, of course, be used. The most convenient mode of making moulds for uon. casting, and that now universally employed, consists in selecting materials, the particles of which possess sufficient cohesion to retain their form, and which yet preserve, at the same time, sufficient openness of texture to allow of the free escape of the heated vapours and gases generated at the moment when the liquid metal comes in contact with the mould into which it is poured. Certain varieties of sand are found to best supply the requisites above indicated ; as they vary, however, in different eases, the qualities of the sand may be considerably modified by the addition of materials possessing more or less cohesive power, such as loam, horse-dung, brick-dnst, plaster, charcoal, &c. The simplest opemtion in the foundry consists in making up a bed of sand; pressing a wooden or metal pattern into it; removing the pattern, leaving an imprint of it in tlie sand; and running into the imprint hquid metal, which, on cooling, hardens, and retains the form of the pattern. In order to prevent the weight of the liquid metal displacing the bank of sand, it is necessary to confine the latter in a box. It must be obvious, that where one such box alone is employed the upper face of the casting can only be the level assumed by the liquid metal on running into the open moidd. Where, therefore, the casting requires to have a precise form given it on both sides, two sncli boxes nmst be employed, the cavities in the one being secured over, and opposite to, those in the other, an aperture being made, so as to allow of pouring the metal in to flU up the hollow formed between them. The ordinary bullet-mould afibrds an illustration of the simplest form of ramdding in two parts. Where the form of the pattern is complex several other boxes are frequently added, and the whole being securely bound together, the metal fills up the cavities formed by the impression of the pattern at then planes of contact. The adhesion of these jjlanes is prevented by powdering them over with fine dry brickdust. The notes on this subject contained in Mr. Holtzappfel's admirable work, "Turning and Mechanical Manipulation," Vol. I., are so perfectly clear, that we have ventured on a somewhat long quotation i " The perfection of castings depends much on the skifi of the pattern-maker, who should thoroughly understand the practice of the moulder, or he is liable to make the patterns in such a manner that they cannot be used, or, at any rate, be well used. " Straight-grained deal, pine, and mahogany, are the best woods for making patterns, as they stand the best : screws should be used in preference to nails, as alterations are then more easily made in the models ; and glue joints, such as dovetails, tenons, and dowels, are also good, ns regards the after use of the saw and plane for corrections and alterations. " Foundry patterns should be always made a little taper in the parts which enter most deeply into the sand, in order to assist their removal from the same, when their purposes will not be materially interfered with by such tapering. The pattern- maker, therefore, works most of the thicknesses, and the sides or edges, both internol and external, a little out of parallel or square, perhaps as much as about one-sLxteenth to one-eighth of an inch in the foot, sometimes much more. " When foundry patterns are e.\actly parallel, the friction of the sand ag,ainst their sides is so great, when they penetrate deeply, that it requh-cs considerable force to extract them, which violence tears down the sand, unless the patterns are much knocked about in the mould to enlarge the space around them. This rough usage frequently injures the patterns, and causes the castings to become irregularly larger than intended, and also defective in point of shape, from the mischief sustauied by the moulds, all which evils are much lessened when the patterns are made consistently taper and very smooth. "It must be distinctly and constantly borne in mind, that although patterns require all the methods, care, and skill of good joinery or cabinet-making, they must not, like such works, be made quite square and parallel, for the reasons stated. Sharp internal angles should, in general, be also avoided, as they leave a sharp edge or ams in the sand, which is liable to be broken down in the removal of the pattern, or to be washed down on the entry of the metal into the mould. Either the angle of the model should be filled with wood, wax, or putty, or the sharp edges of the sand should be chamfered off with the knife or trowel. Sharp internol angles are very injudicious in respect also to the strength of castings, as they seem to denote where they will be hkely to break, and more resemble carpentry than good metallic construction. " Before the patterns reach the founders' hands, all the glue that may have been used in their construction should be carefully scraped off, or it will adhere to and puU down the sand. The best way is to paint or varnish wooden patterns, so as to prevent them from absorbing moisture, as they will then hang to the sand much less, and will retain their forms much better. Whether painted or not. they deliver more freely fi'om the mould when they are well brushed with black-lead, like a stove. " In patterns made in the lathe exactly the same conditions ore required : the parts which enter deeply into the sand should be neither exactly cylindrical nor plane surfaces, but either a little coned or rounded, as the ease may be; and the internal angles should not be turned exactly to their ultimate form, but rather filed in, or rounded, to save the breakin., down of the sharp edges of the mould. FORMATIVE PROCESSES. xxix " Foundiy patterns are also made in metal : these arc very excellent, as they are permanent ; and, when very small, are less apt to be bloM'n away by the bellows used for removing the loose sand and dust from the moulds. To preserve iron patterns from rusting, and to make them deliver more easily, they should be allowed to get slightly rusty, by lying one night on the damp sand ; next they should be warmed sufficiently to melt bees'-wax, which is then rubbed all over them, and in great part removed, and then polished with a hard brush when cold. Wax is also used by the founder for stopping up any httle holes in the wooden patterns : whitening is likemse employed, as a quicker, but l(;ss carcfu! expedient ; and very rough patterns are scared with a hot iron. The good workman, however, leaves no necessity for these corrections ; and the perfection of the pattern is wvU repaid by the superior character of the castings. " Metal patterns frequently require to have holes tapped into them for receiving screwed wires, by way of handles, for lifting them out of the sand ; and, in like manner, large wooden patterns should have screwed metal plates let hito them for the same purpose, or the founder is compelled to drive pointed wires into them to serve as handles, which is an injurious practice. " It is invariably necessary to work patterns in some degi-ee larger than the intended iron castings, to allow for the contraction in cooling, which equals from about the ninety-fifth to the ninety-eighth part of their length, or nearly one per cent. This allowance is very easily and correctly managed by the employment of a contraction-rule, which is made like a surveyor's rod, but one-eighth of an inch longer in every foot than ordinary standard measure. By the employment of such contraction-rulea every portion of the pattern is made proportionably larger without any trouble of calculation. " When a wood pattern is made from which an iron pattern is to be cast, the latter being intended to serve as the per- manent foundry pattern, as there are two shrinkages to allow for, a double contraction-rule is employed, or one the length of which is one quarter of an inch in excess in every foot. These rules are particularly important in setting out alterations in or additions to existing machinery; the latter is measured with the common rule, and the new patterns are set out to the same nominal measures with a single or double contraction-rule, as the case may be, the three being made in some respects dissimilar to avoid confusion in their use. The entire neglect of contraction-rules incurs additional trouble and uncertainty." When the pattern is laid in the "flask," or sand-box, the sand should be beaten in around it, so as to increase the cohesion of the mould, and to admit of its being moved about, reversed, and otherwise arranged, preparatory to the securing together of the boxes, and the admission of the metal between them. Those only who are technically acquainted ■with the extreme difficulty attendant on the conditions of sand-casting, can realise the care and labour necessary to the production of any work of an elaborate chaj-acter, since the slightest under-cutting of the pattern entails a great amount of labour in the preparation of what are called loose cores ; that is to say, such portions of sand as woidd be pidled away in extracting an under-cut pattern ffoin the box in which it had been laid to form an imprint. These are moulded in sand, and require to be adjusted with extreme delicacy, so as to allow the molten metal to run in, in order to produce exactly the requisite form. In large castings the various parts frequently have to be made separately, and adjusted to- gether. The skill acquired by the fitters in concealing these junctions is very great; and it requires a practised eye to detect the existence of a well-finished joint. Considerable experience is required on the part of the designer, suice provision must be made by him to ensiu-e that the contraction of the metal while cooling shall proceed uniformly over the whole of the casting ; since other- wise the portions which retain their heat longest would tear away from those which had set most quickly, and thus the work would be spoUt. With regard to icrou^ht-iron, a description of the ordinary processes of the blacksmith's art could but little interest or assist the artist, and the practice of rolling iron in various sections appertains rather to the civil-engineer than to the metal-worker. The subject, however, is so large in its application to architecture, and to stmctural purposes generally, and so novel and scarcely yet fidly worked out in many of its bearings, that justice could not be done to it by a hasty notice. Wc, tlierefore, consider it wiser to refer the reader to specific treatises on the subject, such as that of Mr. Holtzappfel, rather than to afford imperfect information. We have ah'eady rcl'crrcd to some peculiarities in the execution of ancient blacksmiths' work, and piu'pose explaining some of its further varieties in our description of the plates. II.— CASTING IN BRONZE, AS PRACTISED IN THE PRESENT DAY. The necessity in canyiug on this art of a considerable capital, under the fonn of furnaces, apparatus, material, &c., as well as large accommodation in prenjiscs, has caused the practice of it to be transferred from the hands of artists (who formerly conducted the casting of their own works) into those of regular trade founders. These, from confming themselves altogether to the study of the economy of moulding and melting, have much improved upon the old system of working; but, unfortunately, their efforts to ally their excellent manipulation with the amount of artistic excellence required to bring their productions within the category of works of high art, have in too many cases been unattended with success. When a statue has to be cast by these founders it is moulded in the usual manner adopted for very large plain iron castings, sand and loam being used for the purpose ; these answer well enough for all castings which are to be afterwards wrought by machinery, and in which soundness of texture is the greatest essential. In a work of art, however, perfection in the mould is the chief object, and is of the greatest importance, as after-cooling is never advantageous if carried beyond the mere necessities, which of coiu"se must always arise when objects are cast in numerous pieces. When, therefore, sand and loam are used in large works of art, from theii' not being fine enough to produce the requisite sharpness, nor sufficiently strong to bear without injury the building up of the core and the running of the metal, it becomes necessary for the moulder to make repairs, whicli are but too liable to destroy the form of the model, and necessitate a good deal of tooling, by which much of the precise form of the original is destroyed. In making the moulds of the several pieces (for rarely can a statue be cast in one) much care is required in the arrangement of the ingates, or ducts, for the admission of the liquid metal, and the vents for the air thereby displaced. The practice is to introduce the metal into the lowest part of the mould by pouring it down from the upper part through ingates worked in the joints. The liquid metal thus gradually rising drives out the air from the mould through the vents provided for this purpose, and worked in the same manner us the ingates. Thus the space between the core and the mould, when the latter is removed, is exactly equivalent to the original model on which the mould had been previously made. XXX FORMATIVE PROCESSES. The use of tilt core is to avoid tliu cxcussivi; consumption of metal which would take phice if it were allowed to fill the whole of the mould, aud the mauuer of constructing it is as follows : — When the mould has been made, a layer of clay of the prescribed thickness of the metal is laid on the inside of it, and the remainder of the space filled up with the same material as tlie mould had been composed of; the mould having been taken to pieces, the clay removed, pieces of bronze inserted to keep the core in its place, and the mould again fitted up, a space is left which will eventually be occupied by the metal, provided the ingates and vents work properly. Should, however, the latter not convey away the displaced air, explosions will take place, by which not only will the cast and mould be spoilt, but serious and fatal accidents may probably take place. The composition of the material of which the moulds and cores are constructed is of considerable importance, as it must not only be capable of retaining the impressions imparted to it, but must be able to resist the heat of the molten metal, and also to allow of tlie escape of the gas, which, being genera£ed between the metal and the mould, would, if it could not pass through the latter, hinder the metal from lying close to its surfaces. The sand generally used answers perfectly well in the two last- named points, but its tenacity is not sufficiently great to enable it to hold together in moulding a statue. A composition iias, therefore, been sought for, and that which is usually employed is a compound of equal portions of plaster-of-paris and brick-dnst, worked together to the consistence of clay. In the use of the former tenacity is obtained, while the heat of the metal has no efi'ect on the latter, nor do cither of them impede the required passage of gas. To allow the moving about of these moulds, it is customary to erect thciu on iron bases, and to place u-ons within them for the purpose of counteracting the fragihty of the composition. When finished, iron hoops are placed about them, and they are moved by means of cranes into ovens, and there left for five or six weeks, accf)rding to their size, for the purpose of thoroughly drying them. Any damp would have the effect of impeding the running of the metal, through the bubbles which would arise on the contact of the hot metal with the moisture. Previously to the casting, it is necessary to sink the mould below the ground, pugging it hi well with sand, and placing weights on its top to prevent any part being lifted up on the pouring in of the metal. All measures which will prevent expansion are resorted to, and lastly channels of sand are made from the mouth of the furnace, which, when all is ready, is tapped. The glowing metal flows rapidly out, finding its way through the channel and ingates into the mould; and when it appears again through the vents a good cast is presumed to have taken place: should, however, a burst of flame arise from the moiUd, it may be assumed to import that some failure has taken place : the metal is thrown in all directions to the danger of those in its vicinity; the cast, when examined, will be found to have a honey-combed appearance, and all the work will have to be recommenced, as the same mould will never serve again after such an occurrence. When a foundry is well supplied with all necessary conveniences, and due care is observed, these failures rarely occur : they arc usually tlie result either of negligence or inadequate means. Various are the formula; for the compositions of bronze. The late Mr. Maudslay, who was a competent authority, stated that, for the casting of figures, no better proportion could be used than 91 of copper to 9 of tin; an opinion which subsequent trials have fully substantiated. Zinc is often added to the alloy when in a molten state, as it has the effect of rendering the flow of the metal more free. More than 1^ per cent, however, must not be employed, as, being subject to the action of acids, the surface of the figure would be liable to suffer in its durability. When the cast comes from the mould, or rather when the mould is removed from the cast, as the former as well as the core are reduced in the casting to a state of dust, projections will appear where the metal has run into the ingates and vents ; these runners, as they are called, and also the projections residting from the junctions of the mould, must be cut off, and the chashig tools employed to correct any imperfections which may have occurred. When there is a green coating on the metal it is considered the sign of a good surface beneath ; to arrive at this, emery and water must be employed, which wUl have the effect of removmg the green scurf. The figm-e, having been cast in pieces, it now only remains to fit them together; they are first joined to each other with bolts, and then the joints are filled with molten metal, the parts having been previously embedded in sand, leaving merely the joint exposed. Six or seven inches only are thus soldered at a time, and the thin lines of metal resulting from this operation are removed as before. This process having been properly completed throughout all the junctions, the figure will be rendered as solid as though cast all in one piece, nor will the junctions be visible. An artificial colour is occasionally given to the bronze by subjecting it to the action of acids ; but if it be erected in its natuj'nl colour tlic weather will soon produce that appearance which is sought to be effected by such artificial means, III.— CASTING IN BRONZE, AS PRACTISED IN THE TIME OF CELLINI. (SIXTEENTH CENTURY,) "Wlien we inquire into the processes by which the fine bronze statues of the Cinque-cento period were produced we naturally recur to Cefiini, who has left us such admirable descriptions of his practice. He tells us, that a model of the intended figure, prepai'ed in brick-dust and plaster, mixed to the consistence of clay, of dimensions a little smaller than the real size, is placed on a grating in a deep pit, and thoroughly dried by lighting a fire beneath it. It is then covered over with sheets of modelling wax, of the exact substance which it is intended that the cast bronze shall exhibit, and perfectly finished up with modelling tools to the exact surface of the contemplated bronze statue. To this coating a number of sticks of wax are attached, all turning upwards, in order to serve as vents for the escape of the air, which must be forced out of the lower cavities of the figure on the admission of the metal to the mould ; and which, if not allowed to escape, would obviously prevent the perfect filling up of the extremities. Another series of wax pipes is also arranged, attached to different parts of the figure, and also to the main channel along which the molten metal is destined to pass, the object of which is to facihtate the speedy transmission of the bronze to all parts of the figure. According to the difficulty of the subject, a greater or less number of rods and pegs of bronze are then driven through the wax into the core, and are allowed to project sufficiently to tail into the outer mould, and thus serve, when the wax shall be withdrawn, to steady everything. The whole of the waxwork is then brushed over with a mixture of clay and old white crucibles, mixed to a state of cream, and is gradually coated over to some thickness ; to this succeed layers of earth, clay, aud different mgiedients, the last coating being bound round with u-on tics, &c,, in order to make the mould sufficiently strong to FORMATIVE PROCESSES. coMtiiin aiul support tlic great extra weight of the molten metal. Tiie monhl is then dried, and fire beini^ iiiiide undorneatli and aroiuit! it, the whole is baked together ; the wax is of course liquefied by the heat, and is allowed to run oft' through channels made for its escape, leaving, therefore, a vacant space between the outer and inner moulds. The channels being filled up with fire-clay, the bronze is melted in a furnace, the bottom of which is slightly higher than the top of the statue; and when the bronze is perfectly liquefied it is " tapped," — that is, allowed to run into the conduit which conveys it to the figure. From hence it rushes into the space formerly occupied by the wax, driving the air and gases evolved up the funnels provided for their escape. After the mould is perfectly filled it is allowed to cool, and tlien the onter casing is broken up, the core, as far as possible, removed, any imperfections in the casting repaired, and all the delicate details worked up, chased, matted, punched, or burnished, at tlie discretion of the artist. In very large works a different process is adopted : what is called a piece-mould, or moveable mould,— « ho7i creiur, as the French term it, is formed on the finished clay or plaster statue; each piece of this mould is then lined with sheet-clay, and put together; it is then filled up with coring stuff, from which, as soon as it is sufficiently set, the external mould is taken away bit by bit. The sheet-clay is then removed from each piece separately, and the mould a don creux is built up over the core, leaving, of eoiu-se, an interstice between the inner and outer moulds, equal to the thickness of the sheet-clay. Provision being made for the admission of the metal, for the escape of the air and gases, and for the stability of both the moulds, by passing iron rods and ties in all directions, the casting is effected in an exactly similar mode to tliat already described. It is usual, in all small objects, to give a factitious colour to the bronze, by first heating and then immersing it in different liquids, teclmically termed pickles. IV.^ ORNAMENTAL BRASS -WORK. On iTiquiring into the processes by which objects of this description are produced, we find that when the design is drawn a model is made in Avax ; from which, when coated with lac-varnish, to harden its surface and prevent the adhesion of the sand of which the mould is made, a cast is taken in lead. The imperfections common to eai'ly impressions having been removed by the " repairer" with his small gravers and chisels, a cast is taken in brass, which the " chaser," with his " mats," " punches," " stipple- tools," and "riffies," speedily corrects and reduces to a perfect representation of what is required, and this completes the permanent " model" or " pattern," from which thousands of fac-similes may be made. Simple forms are easily moulded, and leave the sand freely; but where concavities, or under-cuttings, are introduced, much skUI and patience are needed. To copy a purely spherical model, the mould requires to be of two halves only, but in complex designs the mould is composed of many parts, and the time expended in making it occupies several days. Jt is in the judicious discrimination as to the fewest number of pieces and the arrangement of the several "hanging cores," that the evidence of ability on the part of the moulder is chiefly shown. To make the sand which forms the mould more adhesive, it is pounded in a mortar, and its facilities for receiving the impression of minute details are increased by dusting over the surface with powdered loam and ground charcoal. In order to withdraw the original pattern the several parts of the sand-mould are lifted out, by means of small points of wire, and after their removal the pattern is taken out and the cores are replaced; provision being made, by what are termed " ingates," for the intro- duction of the fluid metal, which is melted in Stourbridge-clay crucibles, in an air-furnace, with a clear coke fire. The moulds being closed and held together by wood clamps, the crucible and its contents are removed from the furnace, and the metal poured into the "ingate" or aperture of the mould, in order to fill up the space left by the withdi'awal of the pattern, and to produce an accurate copy of the original model. The surface of a brass casting just removed from its matrix presents an appearance and colour closely resembling copper, whilst any roughness or superfluous metal indicates imperfection in the mould, to remove which, when the forms are simple, the file and turning-lathe will generally suflrce. When a careful degree of flnish is needed the work requires to be "chased" up. When the surface to be cleansed is of a "matted" kind, the aid of acid is called in, by immersion in which a uniform brilliant or a dead-gold appearance is secm'cd. It is in this particular that modern brass-foundry differs from that executed by the skilful artisans of the middle ages, who produced a finished surface by friction or by gilding, through the medium of the mercurial amalgam. In acid finish, attention must be paid to the entire removal of grease, and a preliminary cleansing is absolutely necessary. For the final operation, the acid requires to be completely neutralised, otherwise the action will continue and the surface be destroyed, The dead-gold appearance of much of the modern brass-work was the result of a discovery, which arose out of the accidental circumstance of a piece of work having been left in the acid during the uight. This hint was adopted, acted on, and successfully produced the desired effect. The majority of the brass-work produced on the Continent is still gilt, but the gilding can be closely imitated if some little care is taken in the composition of the metal, and if friction with a "scratch-brush" be applied after dipping. The burnished portions in brass-finishing are produced by steel-burnishers, a little ox-gall being applied to prevent scratching. During this last process, the objects are kept wet from time to time, by immersion in water and argol. After being "dried out" in boxwood- sawdust they are protected from oxidation by a coating of lacquer, composed of spirits of wine, and colomed with a vegetable matter. The article to be lacquered is heated, and the lacquer applied with a camel-ban- pencd. In those objects produced from plates by pressure, the metal is pi-epared by being rolled into a thin sheet. The " dies " are formed of cast-iron or steel, but more corumonly of the latter material : into these dies the design to be copied in rehef is cut or sunk. The impressions ai'e taken by means of a stamp-press, to the falling hammer of which the die, sunk in intagho as described, and technically called " a force," is attached. Annealing follows each blow, and the forces are so changed as to gradually increase in convexity, so that the highest rehef and the minutest details may be brought up. The finish applied is the same as that described in connexion with cast brass-work. Of late years both plain and colom'cd glass have been introduced to a great extent, in combination with brass, and with such success, that upwards of 22,000 pairs of cornice-ends and curtain-holders, into which the improvement has been introduced, have been sold, within the few years which have elapsed since the taking out of the patent, by Messrs. Winficld of Birmingham, xxxti FORMATIVE PROCESSES. v.— GOLDSMITHS' WORK. To work gold with facility, it is requisite to combine with it a small portion of some of the inferior metais, and, in order to efl'ect this combinntion mth certainty as to the result, it is necessary first to obtain the gold in the highest possible state of refinement. This is eft'ectcd, first, by the process known as cnpellation ; that is, melting the gold in a crucible possessing the power of absorbing metallic seoria; in a liquid state ; and, secondly, by " partition ;" that is, exposing very small flakes of gold to the action of hot diluted nitric acid, which, combiniiig with any silver that may be present, and not acting on the gold, leaves the latter quite pnre. It is occasionally necessary, in order to excite the action of the acid on an excessively minute admixtiu-e of silver, to add a super- abundance of the latter metal, in tlie ratio of three to one, which, on lamination and immersion, ensures the exposure of the whole of the gold to the action of the acid. This process is known as that of "quotation." The gold thus purified is mixed with alloys varying according to the destination of the metal, and cast into massive ingots. It may be scarcely necessary to advert to the antiquity of the art of the purification of metals : such passages from the Old Testament as " He is like a refiner's furnace," "He shall sit as a refiner," "I have refined thee, but not for sOver," "the fining-pot is for silver, and the furnace for gold," will no doubt readily suggest themselves. We have been thus particular in describing the refinement of gold, as an analogous mode of treatment serves as the basis for the reduction of all other metals from the intractable to the tractable condition. The process of casting is but rarely made use of in the manufacture of either plate or jewellery, since it invLilves the concealment of a quantity of metal which would produce infinitely more effect if extended by the action of the hammer. Gold is, therefore, usually reduced to the state of sheet or wire previously to being used ; to the former condition by beating or rolhng, to the latter by what is called " drawing." Rolling is effected by passing the massive gold between several rollers, the peripheries of which are so arranged as to approach each other more closely in regular series; and "drawing," by forcing solid cubes of metals through apertures, gradually diminishing in diameter, pierced in harder substances than themselves respectively. In this manner gold-sheet and gold-wire are produced, and a similar mode of operation will reduce almost any other metal to analogous condi- tions. When the roUing process is applied to lead, it is termed " milling." Thus prepared, either in sheet or wire, of slight substance, or excessively thin and dehcate, the gold is ready for the gold- smith or jeweller, who commences beating or twisting it into form, according to the nature of the object he would prodnce. Should he desire to execute embossed work upon it, he first, with a dry jjoint, traces the subject he wishes to represent: then he beats it up, at first with a metal, but subsequently with a wooden hammer, into an ap])roximative form, taking care not to reduce the thickness of the plate too much ; he then proceeds to back up the concave side with a composition of pitch, wax, and brick- dust melted together (a substance so tough as to be called by the medieeval writers "tenax"), and upon the surface of the gold, thus equally supported, he continues to beat and punch until the desired relief and form are attained; then with files, delicate chisels, gravers, and burnishers, he concludes by chasing up the more delicate details, and gets rid of the " tenax " by heating it, until it runs out in a fluid state. In executing large or complex pieces of plate it is usual to work all the principal con- stituent portions separately, taking care to subdivide the design in such a manner that the lines of junction shall, as far as possible, be hidden from observation, and then to unite the several pieces by solder. The theory of soldering once explained will doubtless suggest the different variations requisite to be adopted in the process. Solder is an aUoy of certain metals fusible at a lower temperature than those which require junction. In order to secure perfect tenacity it is desirable that this difference of hardness and fusibility should be as small as possible : and hence the practice has arisen of combining with the solder (in a state of fine powder) certain salts and resins which possess the property of assisting the fusion of the pellicle of metal which they cover, and consequently producing adhesion and incorporation of surface without necessitating the liquefaction of the whole mass of solder. Borax, sal-aramnniac, and common resin, are the most frequently employed of any of these substances. Among workmen, two modes of thus uniting metals are recognised, the one known as hard, the other as soft soldering. Tlie former involves the exposure of the whole object to uitense heat in the furnace, or to the action of the blow-pipe ; the latter is effected by melting lead, tin, and resin together when brought in contact with a heated iron. It is evident that the system of hard soldering must necessarily be so arranged, prior to the commencement of the elaboration of any piece of plate, as to ensure that all the soldering may as far as possible be executed at one time, since, without an extraordinary degree of nicety and attention, exposure to the furnace a second time would undo all that might have been effected at the first operation. Great care must also be taken in any subsequent heating, for the purposes of colouring the gold, &c., that the temperature of the flro shall not be raised above that degree at which the soldered joints would liquefy and become disunited. Without the power of soldering, it would be an impossibility to execute any elaborate work in filigree or torsion of wire ; modes of combination peculiarly appropriate to the design of jewellery in gold, in consequence of the extraordinary pliabihty of the metal. This ])roperty of extreme toughness peculiarly adapts gold to the operation of stamping, — a mechanical process wiiicli materially assists in economising labour, and in reducing the prices of all articles of bijouterie produced through its adoption. It is thus performed;- — An approved design is countersunk, or engraved in intaglio, after the manner of gem-cutting, upon a steel die. This, which is called the " matrix," is struck, by a press similar to that used in coining, into a cube of soft iron, which of course presents the design in relief instead of intaglio ; this soft iron die being tempered into hard steel, is then impressed in another cube of soft iron, and thus a second edition of the matrix is obtained. Prom this second "matrix" as many more dies as may be necessary are obtained by a repetition of the same process, without any risk of injury to the original intaglio. On one or any number of these steel dies, a thin sheet of gold is extended, upon which is placed a thicker sheet of lead. On beating this lead with a hammer, the percussion gradually drives the sheet of gold into the indented form of the steel dies, and, on finally removing the gold, it will be found perfectly adapted to the intaglio into which it has been forced. It is in this way that a large quantity of cheap jewellery is fabricated annually in this and in other countries. In consequence of the cost of the steel dies, they can, however, only be employed by the manufacturer in small patterns, adapted for the most general and whole- sale circnlation. All gold artieh's, xvhcn finished as far as their formation is concerned, require the superficial graces of coloiiring, matting, biu-nishing, pcjlishing, &c. "To gild refined gold" is not altogether such a paradox as might be supposed, since the purer the gold FORMATIVE PROCESSES. xxxiii the more colouring does it require to give it the splendid doep tint that we m iiiucli admire. The process is thus effected ; — A paste is made of equal parts of verdigris and sal-ammoniac, to which is added one-twentieth part of nitre and a little white vinegar ; this paste is spread with a brush over all those portions of the gold proposed to be coloured, to about the thickness of a knife blade, and the piece of plate is then exposed to the fire ; as soon as the verdigris seems consumed, the vessel is plunged, still quite hot, into a bath of cold water impregnated with some alkali. In tliis manner a slight coating of copper is given to tlie gold, which infinitely enhances its beauty. A matted surface is obtained by delicately tapping all the parts requiring a dead sm-face, either with a broken or unbroken punch. Bmiiishing consists in rubbing with a steel or agate burnisher, and is most effectively applied to ^\Iiat may be termed the high lights of the metal-work. General polishing is effected by friction with powders of different degrees of gi-anulation, so as to substitute one series of microscopic scratches for another, until the last become utterly unappreciable by the naked eye, and a briihant lustre is the consequence. VI.— SILVERSMITHS' WORK, AS PRACTISED IN THE PRESENT DAY. The design of a piece of plate of an elaborate description having been cbawn, the modeller proceeds to embody it in wax, finishing every portion of it with a degree of precision equal to that which is requisite for the finished object. Assuming that the body of the work is to be formed in what is called repousse, or beaten-u]) work, a sheet of silver is cut into the form of the object when developed upon a plane surface, and rudely beaten into a hollow, or dish fonu, by wooden mallets. The requisite degree of concavity having been given to it by hammering, ornaments in basso or alto-rehevo are obtained by applying the internal surface to an iron rod, which is made to vibrate by the frequent blows of a hammer on the end of the iron farthest removed from that in contact with the silver. The continued action of these vibrations, regulated by the skill of the workman, gradually gives the requisite form to the ornament. The rough developement of minute projections is obtained by more pointed irons of a similar description. In order to define more perfectly the form of these projections, the silver vessel is filled with a composition of pitch and ashes, so that blows with punches of various sizes may be applied to any part of its exterior without injury to the general form. Wlien by this counteraction the relief of the ornament is modelled up, the finishing touches and fine edges are given by means of chasing with the graver. The pitch is melted out, and that portion of tlic piece of plate is ready for the subsequent processes of cleaning, polishing, &c. Where certain portions of the object require to be cast, the moulder takes a mould in intaglio from tlie original wax model. Into this mould he lays portions of sheet clay, answering in substance to the desired thickness of metal. By pouring in liquid plaster at the back of the clay a core is obtained, on the hardening of which the sheet clay is removed, and melted wax is poured in between the two plaster-moulds to take its place. The small piece of wax thus cast is made to serve as a pattern for the final casting in sand-moidds, the silver being run into the two halves of the mould, so as to fill up the space originally occupied by the wax which was removed to make way for the metal. When the requisite number of these small pieces are cast, and their edges trimmed up, they are neatly fitted one to another. Solder is placed between them, they are connected together by wires, and by the action of a gas blow-pipe upon the solder-joints the whole are united. The patience and dexterity required for foi 'miiig an elaborate piece of work, consisting frequently of from thirty to forty or even more of these small castings may be readily conceived. As an illustration of the extreme difficulty this subdivision of parts involves, it may be noticed that in the formation of the great candehibnun contributed to the Exhibition of 1S51 by Messrs. Hunt and Roskell, there were at one time no fewer than six hundred fragments distributed throughout their workshops, the whole requii-ing to be adjusted and brought together in the manner described, so as to make up the whole object. In order to abridge tlie laboiur consequent upon the formation of frequently-recurring patterns, stamping, by means of steel dies, is often resorted to. These dies, or forces, are engraved in intaglio, and brought down with a heavy pressure upon sheets of metal placed beneath them, in a manner similar to that we have described as necessary for the formation of brass die-work and gold-stamping. In open silver-work the perforations are cut out by hand, but in eommoner work by means of steel dies prepared for the purpose. When the article is completely put together, all the imperfections are removed by riflles and otlu-r tools. Every part is carefully chased, so as to give the utmost precision to the ornaments and variety of texture to the different portions. The whole is then cleaned down and polished by a succession of rapidly-revolving brushes, in connexion with which various substances, of a greater or less degree of fineness, are successively employed, until the scratches at fii'st produced by the operation become imperceptible. In those parts in which a dull finish is desired, the effect is obtained by the application of a small metallic brush : and wliere, on the contrary, extreme brilliancy is required, that result is produced by rubbing the parts with burnishers o( steel or bloodstone. A white frosted appearance, or " dead finish," is obtained by covering parts of the object with a coat of pulverised charcoal and saltpetre, or argol, bringing it to a red-heat over a charcoal fire, and finally quenching it in a pickle of sal enixou. The employment of dies has been carried to so great an extent that many ordinary objects — such as spoons, forks, &c. — can be formed out of sheet-metal at a single blow. VII.— SILVERSMITHS' WORK, AS PRACTISED IN THE TIME OF THEOPHILUS. (TWELFTH CENTURY.) The picture of the method of working the precious metals during the Middle Ages afforded in the writings of Theophilus* is so perfect, that, although it enters into somewhat ]5rolix detail, we have determined on printing his description of making the "large chalice" intact. "If you wish," says he, "to construct a large silver chalice of four, or six, or ten marks, you will first purify and prove all the silver in the fire ; aftenvards divide it in the order before described.! After this take two pieces of iron, • Wc are glad here to be enabled to express our ileep gratitude to Mr. Hcodi-ic for bringing this autbor .so prominently before tbc public, and for euricliiiig liia traiisJution with, such eopiotis and admirable nutca. + See Theophilus, book iii. ehap. 24-26. xxxiv FORMATIVE PROCESSES. equally long nnd wide, of the measure of a palm and thick as a straw, evenly beaten and without Haw, and carefully smoothed with a plaue ; make between these m iron biudiiig, beaten smoothly and moderately thick, which you will bend in fashion of a circle, of such size as it may be apparent to you that it can be filled with the silver you wish to cast in it. And when you linvc bent it dti not join the ends together, but you will separate them a little, that an opening may appear through which you can pour in. You will adapt this circle equally between the two iron (plates), so that its ends may appear a little beyond the irons, and bind these with three strong iron hooks in three places, namely, below and on each side near the opening, and thus plaster beaten clay around the circle, between the irons, and abundantly about the opening. When this mould has become dry you warm it, and pour in the melted silver. All gold and silver which is founded in this manner is always sound (unless it happen through great negligence) for working in it whatever you may wish. You wdl measure the circles, also, according to the quantity which you wish to found, and you make larger and smaller: after you have beaten out the melted silver as above, fill it with wax, and beat it on the body, if you wish to hiive ribs flat or round; these stand around like small spoons, both wdiich kinds of work give great ornament to the chalice. " If you wish to ornament which ribs with niello take heed of tins, that the silver be thicker, and so act that one rib may be gilt and the other blackened i it is always necessary that they shoidd be in pairs. When you have beaten out these, file them evenly, and portray Greek foliage in those places which you wish to make black, and carve with a bold stroke, and sculpture their grounds with graceful circles and with fine work. " O/i applii'ing the Gems and Pearls.' — Afterwards cut these in pieces, like straps, so that every l)and may have a wire, wliich you will bend together, and make small settings of them, by which the stones may be enclosed, large nnd small, to the size of each one, and you wdl arrange them in their places. You will also have flour of wheat or rye, whi(:li you will mix with water in a small cup and place over the coals, that it may become a little warm. In this you dip these settings slightly, one by one, each in the lower part, and so fix them in their place. All being made fast, place the piece of gold upon which you have fastened them over the coals, until the nmisture of the flour is dried, and they will soon adhere. Take also the fine wire and beat it slightly upon the anvil, so that it may be rather thin, and yet that the beads above and below may not project nor lose then- form ; with them you will weave flowers, large and small, with which you wdl fill up all the grounds between the settings. AVhen you have formed these with the fine pincers, dip them into the wet flour, and you will thus put each into its place. Which being done, place it over the coals that it may become dry, and immediately anoint the soldering, and solder it as above. Both pieces of one handle being soldered and made firm, join them together, and place a foundation to them around them near their inner edge, — namely, a thiu piece of gold, which may be like a straw, and smooth everywhere. When you have joined which piece between the two, bend three small thin pieces of iron, and make small stays, which can hold the outer pieces of gold in three places outside, so that the third, which compasses the inside near the edge, cannot be disunited. This being done, anomt the solder everywhere, and you will dry it a little over the fire, and the coals being arranged and glowing, you make a hollow among them, in which you place the handle, and about this you will arrange the coals in order, so that they may not touch the gold, but rise around it like a wall, until they dominate the gold; and you will then place above it two or three slight pieces of iron, which may pass across. Over this yon will place the coals everywhere, and cover it carefully — so, however, that some open- ings may remain among these coals, through which you can see how the solder flows. AVlieu you see which, instantly sprinkle it with a little water : you take it out, and will gently wash and dry it, and, carefully considering it, if there is any fault you correct it, and again anointing it as before, you mil solder it ; and do this until it is made firm everywhere. In this manner you wdl make the other handle, and solder it. Which being accomplished, join them both to the cup of the chalice in their places, and make tw^o lines upon the cup itself with a graver, by means of w-hich you can see whether they ai"e placed straight in soldering. Then melt piu-e gold, and mix with it a third part of red and pure copper, which, likewise fused and slightly beaten, you will file altogether and place in a goose-quill. After this accumulate before tlie furnace a great heap of coals, and place ill them the cup of the chalice, so that half of it may be altogether under the coals, and that part upon which a part of the handle is to be placed may altogether rise above them ; you immediately join which (handle) on to it, and anomt the vase with the handle, inside and out, with the soldering, and you will scatter the filings which you had placed in the quill inside and out with the solder, about the junction by which the handle is miited to the cup ; and thus, fire being placed around, you will heap the coals in a curcle, as you did before about the handle, and place the irons over it, which you cover plentifully with coals. In the front part, within the hollow of the cup, place the coals in the shape of a small furnace, so that the coals may lie thickly around the circumference, and that a small opening may appear in the midst, through which it can be blown, that the heat above and below may be equal. And when you see the solder flow about, and as if undulating, a third time, sprinkle it carefully with a little water, and, taking it out, wash and dry it, and again solder it similarly, and until it adhere very firmly. And, turning the vase on the other side, join and solder the fellow-handle in the same manner," VIII.— CELLINI'S METHOD OF MAKING LARGE SILVER VESSELS BY REPOUSSE, AND VARIOUS PROCESSES OF CASTING. The following description is closely translated from the twelfth chapter of the celebrated Treatise on Goldsmiths' Work, by the great Eiorentine: — "The silver having been cast in iron plates should be left to cool, as they thereby become harder and more solid. AVIieii cold, the dross should be removed from their sm-l'aces. A razor some\\diat blunted, and two-and-a-half fingers wide, slioukl now be provided and fixed upon a stick, which should have in the form of a cross two handles, these latter being about a half braccio (one foot English) from the point of the razor, which shoidd be bent about three fingers, and prepared so as to scratch; for with this razor the plates of gold or silver (as the case may be) will have to be scraped in the following manner : — The plate must be heated till red as the fire, and thus hot placed on the sheet of iron used for its casting, to which it must be nailed. The * Thcophilus, book iii, chap. S3. FORMATIVE PROCESSES. XXXV stick on which the razor is fixed being placed against the ivorkman's shoulder, with both his hands on the handles (forming t!ie cross), he should scrape forcibly on the sheet till the sm-face of the silver appears and becomes clean. " I will in this place mention some things I observed when working in Paris, wliere I executed works of tiie greatest difficulty, and of the largest size possible, iu massive plate-work. Wliile I was scraping some silver sheet in the above described manner, a workman of mine, a Fleming, named Claude, a very ingenious and able young man, observed to me, that altho\igh my method of scraping the plates was very excellent, still in the way in which he was accustomed to work them, both the time and tlte scraping were saved. Hearing this, I said I should be glad to learn his method, and thereupon I gave into his hands a pair of silver vases weiglung about twenty pounds each, for him to execute, following however my models. When he had melted and cast his silver, and cleaned off the dross, he began beating the plate without scraping it, and gave it its proper form, as we shall describe further on ; thus did he save the labour of the scraping, a plan worthy I think of imitation. Many other excellent methods did I also learn there, which I at first thought were in consequence of their working in excessively fine sdver, but I afterwards found that it resulted from their great skill in this art; for I saw that all the inferior alloys of silver were finished with the same facility and perfection as were observable in works of real silver. Thus did they work without spending any time in scraping the plate, not failing, however, to remove, as they showed themselves, any flakes which the plates might from time to time throw up. Notwithstanding all these advantages, on reflection, I should prefer the first to the second method, that is to say, the scraping system, for the reason that I have found it Iji.'tti.'r, "I will now describe the way of making a vase of an egg-shaped form. Amongst the number wliich I had to make in Rome there were two of this shape, more than a braccio (about two feet English) in height, with their handles and with moutlis contracted at the top ; they were also wrought with foliage and diverse animals : one of them was for the Bishop of Salamanca, and the other for Cardinal Cibo. Vases of this sort arc called ewers, and are placed upon buffets for the purpose of display. All the numerous vases I made for King Francis, which were much larger than the above, and on which I wrought with much care several chased works, I executed after the same method. When I had cleaned the plate of its dross and cut off the corners, I scraped it on both sides in the manner I have before described; and as it liappcns that the plates are cast longer one way than the other, by using the hammer I brought them into a round form ; and when the plate had been heated to a red heat (not too much so, however, or it might split), I placed it on the anvil and beat it with the point of the hammer sharply from one angle to the other, driving the pouit well into the metal. I continued thus hammering from ah foiu- corners, till the lines of hammering crossed each other, and then also with the point of the hammer I worked towards the sides ; after so beating and heating it four times, I succeeded in making it round. Having determined the measm-e of how wide the body of the vase was intended to be, I worked the plate to tiii-ee fingers more than that width, always observing to keep the plate as thick in the middle as possible ; before, however, this size is obtained by hammering, the centre should be determined as follows : — Place upright on an anvil a pointed iron tool, one flnger thick and six long, not sharp but blunt-pointed ; on this the plate must be balanced till it is quite sti-aight and even, and when so, let an intelligent boy give a blow with the face of the hammer directly on the part over the point, so as to mark it on the plate. Many workmen are able to do this without any help, particularly with small plates, but in the larger ones it cannot be dispensed with. The plate shoidd then be tm-ned over upon the anvil, and using a hammer upon the iron point, the mark should be made stronger ; a pair of compasses being now applied, using this mark as a centre, as they are turned round, the inequalities of the plate will become apparent ; and by continually re-heating and re-hammering, the silver will be transferred to tliose places where it may be wanting, being very careful, however, not to lose the point of the centre. The plate having been -worked to a size of three fingers larger than the body of the vase is intended to be, the compasses should be again applied, and besides the cu-cle we have mentioned, several others should be made, about a finger's width from each other, until they come up to the centre. A sort of hammers must be now used, the heads of which ai-e a finger thick in the points and a finger and a half on the other face ; the points should liave the corners rounded off, and shaped as is the ficsliy point of a finger; with these the plate should be beaten, commencing from the middle, that is to say, the actual centre, being careful not to lose the mark, renewing it by striking with the same point we previously described in marking it in the first instance; and working witli the hammer iu a spkal manner round the marks and circles made by the compasses, heating the plate continually. Beating it in this manner, the silver mil spread out in the fonn of a cup, such as the body of the vase requires. Having been careful to keep the point of the middle, the silver must be hammered out equally, for, should it hang more on one side than the other, the silver would be unequally distributed and the work would be ugly. Beat thus the plate, til! it becomes as deep as the body of the model is high, and then, using various anvils suitable to the form of the vase, and striking with either the face or the point of the hammer, and sometimes without placing it on the anvil, the beating shoidd be continued till the plate has taken the entire form of the vase; the name given to these anvils is cow's tongue {Ihiffua di vacca). The rim or projection should be levelled at this time, as it determines the proportion of the body of the vase ; this is done upon a sort of bent anvil made for this purpose. The beating should be commenced by degrees, holding it in the most advantageous way for facilitating the contraction of the neck, always being careful to remove any flakes which may, as the work proceeds, make their appearance. AVIien, then, the neck has been contracted and formed according to the model, if basso-relievo have to be introduced into the body of the vase, it shoidd be filled with black pitch, and shoidd be set out and drawn upon with a burnished steel graver ; either figures, foliage, or animals, being the subjects, according as the artists may desire to ornament it. The whole should afterwards be carefully redrawn with a pen and ink, with all that neatness and skill which is looked for in good drawing, after which the punches are to be used. These are iron tools of the length of a finger and large as a goose- quill, increasing up to the size of two quills, and are arranged in various shapes. Some of them are made like the letter C, beginning with the size of a small c, and increasing up to that of a large one. Some are much twisted, others less so, &c., tOl at last they come to be quite straight. These last, in diminishing, should finish with being the size of a man's thumb- nail, the diminutions extending to the number of sk. These punches, being applied to the work, should be skilfully struck with a hammer of the weight of three or four ounces, thus by their means profiling all that had been drawn. When this has been done, the vase should be surrounded with a slow fire, for the purpose of removing the pitch which had been put within it, and then it shoidd be boiled in a mixture of tai-tar and salt, in equal quantities, as has been already described. "Another description of iron tools is now to be used; these are called snarling-irons, and are a sort of anvil with long horns, made of pure iron, long or short as may be wanted; they require to be fixed in a block, as is customary with other anvils. XNXVI FORMATIVE PROCESSES. One of tlie horns is placed within tlie vase, with the point (which should be rounded in the form of the little finger of the hand) turned upwards; this horn of the snarling-iron will cause that part of the work of tlie vase against which it is placed to rise as may be desired, by striking with the hammer the other horn, making the former one, which is in the vase, to vibrate upon the silver, and so bulge it out as much as may be wished. Having thus raised all the figures, animals, or foliage which had been desif^ned, the vase should be re-heated and whiteued as before mentioned, and then be replaced in the pitch and worked with other chisels made as above; except that their ends should be of the form of beans, and diminishing from large to small, jj, jg jj^ip ^j^jjj other shapes than these are used, according to the customs of the artificers, for various are the methods I have seen adopted by masters of this art. This, Iiowever, is of little importance; it. is sufficient to say that the tools arc required to bulge and not to cut the silver. " To return, however, to our description, tlic work should be again removed from the pitch, and re-heated ; this should be repeated two or three times, as may be requu'ed. When tlie figures, &c, are brought nearly to the last finishing, remove the vase fi'om the pitch, and work with wax upon the mouth and handle of it various elegant and fancifid devices, improving them from the first-made model ; when these ornaments have been completed in the wax they should be moxilded. The methods of doing this are various : some of thera we think important to be described for the benefit of the artificer. "I will begin, then, with that which I consider the easiest, and which I adopted in working the vases for King Francis. I first took some of the earth used by the casters of cannon, which being dried I sifted well, and then mixed with it some shearings of fine cloth, and a little cow-dung passed through a sieve ; all of which I beat carefully together. I then ground some tripoly, and haviu" made it as liquid as a painter's colour, I laid it upon the wax modelling, (to which I had added in the same wax all the inmates and vents required in casting; placing, as was my custom, all the vents below, and bringing them up to the ingates above, being careful in casting to keep these vents so far away from the ingates that the silver may not run into them, and so prevent their acting properly,) and having laid on one coat only of this ground tripoly, I left it to dry, and afterwards I laid over it a quantity of the mixture of earth, &c., as much as would, when dry, be of the thickness of a finger; this also I left to drv, and then I bound the work round with iron wire, upon which again I laid more of the mixture, but not so thickly as before : the purpose of this is that it may hold the portion laid first more tightly. The whole should now be brought close to the fire, keeping the mouth of the wax downwards over a basin ; and by exposing it to a temperate fire, the wax will by degrees run out. Care should be taken not to make the heat too great, for should the wax boil in the mould the latter would be spoilt. The wax having been withdrawn, the mould will separate of itself from the vase. Thus the wax being removed, that part which was attached to the vase should be well closed with the mixtm-e, and tied up in various places with fine iron wire; adding again some more of the mixture until the wire is no longer visible'; and then the whole should be placed to bake in a brirk iuLii;ice supphed with charcoal, the latter being fired at the same time that the mould is placed within. With this species of cartli the whole heat of the fire may be applied at once, which cannot be done with other earths not mixed and compounded as is the one in question. "When the mould is well baked, and whilst the silver is melting, place it within an earthenware pot capable of easily receiving it, and fill up the unoccupied space with sand, not wet; but somewhat damp; this will bind the mould in the same way as is done with those of cannon placed in trenches. When the silver is melted, cool it with some well-pounded tartar, and have ready a piece of linen cloth folded in three or four folds, well saturated with oil or grease, to place over the mouth of the crucible ; then take up the crucible with the pincers, and pour the melted silver into the mould. The workman should have several sizes of these pincers, large, medium, and small, according to the quality of the diff'erent crucibles, and to the quantity of silver required to be melted;. for they are useful in binding the crucible together, so that it may not break, a danger to which the artificer is much subject ; for it often happens, that, in beginning to pour in Uie silver, when a small quantity has gone in, the crucible cracks, and all the labour of the workman is destroyed in a moment. Let the artificer then in this process exercise his greatest skill and care ; and whilst he is filling the mould let bim direct an assistant to hold with a pair of tongs the piece of linen cloth, so that it may not fall from the mouth of the crucible ; for by retaining it there the silver is kept hot, and, moreover, it prevents any bit of coal or other matter falling into the mould. " It sometimes happens that there are on the vase some little masks, as is indeed customary. When the wax has been detached from the vase, the moulds of these masks should be taken, and in the hollow a layer of wax, of the thickness of a thin knife-blade, more or less, should be laid, in substance according to the required solidity of silver ; taking care that it be equally distended ; this wax, on account of its equality and thinness, is called ' la lasagna,' (a thin paste made in Italy). To this mould, having made also in wax the ingates and vents as described before, (namely, attached to the bottom, and coming up to the ingate,) cover it altogether with the before-mentioned composition, and tie it up in the same way with iron wire, and pom- in the silver. The handles and feet also of the vase should be cast in the same manner, and should not be wrought with the hammer : in large vases particularly I would advise the artificer to make feet by casting, for, having to bear so much greater weight, were they beaten out of sheet they might twist. " I wiU mention, also, one or two other methods of moulding this sort of things, so that the artificer may select tliat which most suits him. The one which follows is very much to the purpose. "I pounded some fresh moulding plaster and passed it through a sieve, the like I did also to a brick of terra cotta ; I took two-thirds of the latter, and the same quantity of plaster, and diluted both of these with water till they were of the consistency of a sauce, adding thereto some burnt plaster. Using then a soft hog-hair brush, I laid this composition upon the wax, in the same way as I had done with the mixture of earth. But the plaster should be all laid on at once (for if laid gradually it sets), and afterwards, with a wooden trowel or ladle made for the purpose, add as nmeli of it as the thickness of a finger, and then leave it to set. When it has done so, tie the mould with fine, well-tempered ii'on wire, and then dilute with water the remaining brick and chalk which has not passed through the sieve, and put it over the mould to the thickness of a knife-blade, and so that it may perfectly cover the iron wire ; always observing, that the larger the mould the thicker must this outer shell be. When the artificer is not driven by hurry to finish the work quickly, as is generally the case, he should place the mould in the sun, or some dry place, or where there is smoke, and there leave it tiU all dampness has left it. After this, with a temperate fire, he should cause the wax to run out ; when it is all removed he should quickly increase the fire, and bake his moiJd in the same manner as we described that of earth, &c. to be baked. This is all that has to be done in this system of moulding ; I hold it to be an excellent one, and very suitable for expedition, according as the artificer may be more or less pressed for time FORMATIVE PROCESSES. xxxvii in finishing his work. There is another manner of casting the above-mentioned articles wliich I will also describe. The workman should take the wax models and divide them into several pieces, and then mould them in powdered earth and in boxes, as before explained. When they are moulded in the best way they can be (and I now s])eak of tlie under-cuttings, which arc unable to come out of the powder), cast these latter in lead; they can be then cleaned and thinned as the master may desire; after this mould them, and cast the silver in the same boxes. This is also an excellent method, because, when the artificer has motdded the wax models in lead, he can reduce thcLi' thickness according to his wish ; moreover, these lead-moulds wi!l sei-ve on such other occasions as may occur." * IX.— THE ARTS OF CHASING, JOINING, SOLDERING, SANDING AND GRAINING, OR GIVING TEXTURE, BURNISHING, HATCHING, AND COLOURING PLATE OF THE CINQUE-CENTO PERIOD. The following very interesting and characteristic account is also translated from the " Trattato dell' Oreticeria" (Chapter 5) ; — "All those articles, which amongst goldsmiths are called small-ware work, are wrought with punches and chisels; such as rings, pendants, or earrings, bracelets, and certain medallions (worn in hats and caps) made from very thin gold-plates, on which figures are worked in low, half, and perfect rehef. Amongst goldsmiths, Caradosso da Milano, who, in the times of the Popes Leo, Adrian, and Clement, executed many most excellent works of this description, remains, in my mind, unsurpassed. "In treating of the two nsual methods of working with the chisel, one of them being less easy of execution than the other, we will first describe that followed by Caradosso, which was the most difficult of the two. " That worthy artificer made, in the first place, a most careful model in wax of his subject, and filling up with clay the under- cuttings, cast it in bronze ; he then took a plate of gold, the thickness of which increased towards the centre, not so much, how- ever, that he could not easily bend it, its width being also greater than that of his model. Having heated and worked the plate to a raised form, he placed it on the bronze model, and then hammered it with tools or punches made of birch or wild cherry, gradually causing the plate to take the forms of the figures on the model; taking care, however, that the gold should not break, using his tools, whether of iron or wood, with great dexterity on either side of the plate, and always striving to render the gold of an equal thickness thronghout. The carefidness of Caradosso in this was very great. " When he liad brought the medallion to the height of relief he desired, lie commenced the forcing of the metal between the legs and arms and behind the heads of the figures ; giving to this much attention : and havmg brought the parts so well together that their edges joined, he cut away the grounds which remained under the legs, arms, and other parts of these figures, as he also did to all the remaining parts which were detached from the field, + " The work being brought to this point, he commenced the joining it by the method called soldering by fusion or heat, which he did as follows. He took a lump of verdigris in its purest state (not having been previously used for any purpose), the size of a walnut without the rind, a sixth part of sal-ammoniac, and as much borax ; ground them well together, and with the addition of a little very pure and clean water, liquefied them in a glazed bowl. When this composition became of the consistence of an oil-colour, he, with a wii-e, laid a slight thickness of it upon the before-mentioned parts to be joiued, i. c. between the arms and other parts of the figures ; and upon this composition of verdigris he placed with his borax-box a little well-gi'ound borax : he then made a fire of pure unused charcoal, and placed his ivork in it, arranging the ends of the charcoal so that tltey turned towards the parts he wished to join, for the reason that the ends breathe or pufl' out a little, and adjusted some pieces also over the work, in the manner of a grating, taking care, however, that they should not touch it. When the metal became of the same coloiu: as the fire, he began blowing with a pair of small bellows, in such a manner that he caused the fiames to play all around his object. Should, however, the stream of wind be too strong, a danger woidd be caused of the work melting and being thereby spoilt : for this reason he observed the gi-eatest care, and watched for the glittering and moving of the first pellicle, as it is called, or outer coating of the gold. As soon as this took ]ilace, he c[uickly sprinkled his work with a little brush dipped in water; and in this manner the parts became most excellently joined without any solder at all. Having, by the above method— (which is not called soldering, but is rather bringing the whole work into one piece, for such is the power of the verdigris in company with sal-ammoniac and borax, that only the first pellicle or outer coating of the gold is by their agency moved ; and being slightly melted, these outer surfaces of the gold join in such a manner that the whole becomes equally entire and solid), — Caradosso having, as I said, thus joined his work, placed it in very strong white vinegar, adding thereto a little salt, and so left it a whole night. The effect of this was, that in the morning he found it whitened and cleaned from the borax. He next took some stucco.J with which he filled the whole of his work, so as to be able to work on it with his chisels or punches, which he had provided of all sizes, gradually diminishing from large to small, and made without a cutting edge, havmg to be used for bruising or denting, and not for cutting away. "In working the metal, some small holes or cracks will unavoidably occur; the method of joining with verdigris, "&c., above described, must not, in these cases, be adopted, but a solder should be used made as follows : — Melt six carats of fine gold, and, when liquefied, add of fine silver and copper together one carat and a half. With this solder, or stopping, the holes or cracks made in working should be filled up ; and every time a soldering takes place some of this ' stopping ' should be put on the holes previously so stopped, so that the subsequent soldering may not cause the previous one to run. All parts of the work being thus soldered, he again placed it on the stucco and re-worked it with care and patience till he had brought it to perfection. " This is the whole of the method follo^ved by Caradosso, which I freely confess I learnt from him, nor am I unwilling to do SO; indeed, obhged and grateful, I continually rctiu-n him infinite thanks and praise (for to me there is no greater vice than ingratitude), not wishing to assimilate myself to many who, having but just received a benefit, instead of feeling an obligation to their benefactor, strive dh-ectly to injure and malignantly oppress him. As, however, it happens that I have another method of working to speak * In tliia way, probably, the singular lead-caata used by Fran9ois Briot were made. t "The plate should be made of the beat gold, of at least 22 carats, that of 23 being too soft for working, and that of 21.1 too hard and dangerous in soldering," J "This stucco he made of Greek pitch, mixed with a little yellow was and some wcll-po\i tided brick." XXXVIll FORMATIVE PROCESSES. of easier than that of Caradosso, and containing some particulars not practised by him, I do not do so with any intention of obsciu'ing in the sHghtest manner his fame; the many acknowledgments made by me showing the obhgation I feel to him: bnt as it often occnrs that additions can easily be made to things already in operation, so it has chanced to nie in this matter. " I now say, then, that when the model has been made in wax and the design determined, a plate of gold of the form before described (viz. thicker in the middle than at the sides) should be worked slowly on the reverse side with the large chisels or punches, bulging it roughly or sketchily in the form of the wax model. Working in this way, the bronze model used by Caradosso is not required, and the work would thus be much advanced in less time than the bronze model could be cast; moreover, the slight staiuiu" of the gold, caused by the bronze every time the metal is heated, is not required to be removed, as it is iu the other case, by glass dust (a very iiseful material, however, as it removes all fumes arising from the bronze). *' By following the above method the artificer will avoid those impediments I have indicated, and will be able quickly to re-heat his work without ever having to sand it. As some pieces which I worked by this system here occur to me, in speaking of them, and shortly describing the manner in which I treated them, I think I shall better succeed in explaining to the reader what I would say. " A Siennese gentleman, named Girolamo Maretta, commissioned me to make a gold medallion for Imu : iu this I introduced a Hercules accomplishing the labour of tearing open the jaws of the' lion. I made these figures in whole relief, and so much were they detached, that the heads hardly seemed to touch the ground, so slight were the junctions. This piece I executed without making a bronze model, following the last- mentioned method, striking alternately on the face and on the back of the plate ; with snch patience and care did I finish it, that it gained nie this reward (and I say it with the greatest satisfaction), that the most excellent Michelagnolo Buonaroti condescended to come even to the chamber in which I worked to see it ; as is known to many worHiv m-tificers who were present on the occasion. This occurred at Florence in the year 1528. This most wonderful man having exammpd ray work, spoke of it in these (his own) terms (I do not, however, wish therefore to make these words a matter of met'chaTidise, or to exalt myself, as many artificers with unbridled ambition are in the habit of doing, adapting in all their discourses (Expressions purporting to have been used by him ; it having been niy practice ever to strive rather for the reality than for a mere appearance), — having, as I said, examined with a careful eye the outlines, the muscles, and the attitudes of these small figures, — be said — ' If this little work, finished with that cai-e and beauty which I observe in it, had been caiTied out in a large size, either in marble or bronze, we should have seen a marvellous work ; and to my mind I do not believe the ancient goldsmiths could have executed their works with more excellence than I find in this.' So much did these words excite me to work, that I set myself to make large figOTes ; and the more so, from its having been afterwards told to ine that Michelagnolo expressed himself to the effect, that one who had completed with such perfection a small work would not, in one of a larger description, have arrived at the same happy result. Not for the purpose of overthrowing the opinion of such a man, but so that I might by study and practice avoid such impediments as, in the carving in marble or in the casting in bronze of large figures, might have prevented me from attaining that true and esteemed manner go nmch sought after in these arts, did I therefore set myself to carve and cast krge subjects in marble and in bronze. " But to return to the point from whence I digressed. The medallion having been seen by Frederigo Ginori, a Florentine gentleman, who much esteemed skilful persons, he requested me to make one also for him. Being of a truly noble mind, and having placed his affection upon a lady of high rank, he expressed his own idea, by mshing for an Atlas sustaining heaven, according to the fiction of the poets, — giving the spirit to his invention by adding the motto, ' Smuma tulisse juvat.' When I heard this, I set myself with great pleasure to serve him, and did so in this manner. I first made a small model with careful study, and then I resolved so to make the medalhon, that it should have the field of lapis lazuli; and the heavens wliich Atlas is described to bear on his back (the Atlas I had already modelled in wliite wnt) I made of crystal; cutting thereon with careful design the zodiac and other figures of stars. This done, I prepared a plate of gold, and, with great patience, by degrees I brought into relief the figm-e of Atlas; by holding in front a small round anvil, on which, from time to time working, I, with a small hammer, drew the gold of the field, putting it in the arms and legs of the same figure, for the purpose of equalising the thicknesses : in this manner did I almost finish the figure. This method is called ' working in the round,' from the work having nothing underneath, as would be the case when placed on pitch, t. c, on the before-mentioned stucco. When I had broiight ray work to the point I have mentioned, I filled it with stncco, or pitch, as we arc accustomed to call it, and by means of punches or chisels I brought it up to the point I wished. I then detached it by degrees from its field of gold; but this is very difficult to explain in words. I will, however, try to do so in the best manner I am able. We have said in what manner the anus and legs of the figures are joined, leaving them attached to the field of the medallion ; but in the method we are speaking of they have to be detached from the field. The artificer, working on a little anvil with a small hammer, should strike gently with its point, and giving a slight action to his hand should, with the punches, so strike within and on the sides, as to cause the figures to become swelled up on the field. W^hen it is required that the figm-es should be left detached upon the field, it should never be bulged up, and for this reason care should be taken that the field of the said figure does not get out of its level ; but as in the present case of which we are treathig the field is not required, it should be bulged and forced out wherever the workman may think fit. When he shall see that there remains sufficient gold to enable him to join the back of the figure, then he should separate it from tlie rest of the field, and, with the gold remaining on the figiu-e, joining it gently, he should solder it, and give it the last touches and finishing, without placing it any more on the stucco : he should be careful also not to allow any opening to remain in his work through which the stucco might pass. In such manner, then, did 1 finish my Atlas ; and on those portions of the figure which were to be placed on the lapis lazuli which I had chosen for the field of the medallion, I soldered two strong stems of gold, and having pierced the lapis, I secured it well thereon. Having thus finished the figure, I placed the crystal ball (representing the heavens, and therefore engraved with the zodiac and other celestial figures) u])on Atlas' shoulders, it being also supported by his u])raised hands. I then added, as a finish to the medallion, an ornament of gold, full of leaves, flowers, fruits, and other beautiful things, within which I set it. Thus completed, I gave it to the gentleman, who expressed himself highly contented with it ; and at his death (for he died very young) he left it a legacy to Luigi Alamanni, a most excellent poet,* and his particular friend : the latter, after the siege of Florence, going to France into the service of King Francis, gave it to that king, considering it a fit present for such a lord. This medallion being greatly * Author of tlie " Coltivaiioiii' ili Riao." FORMATIVE PROCESSES.

" Being also fit for our pm-pose, I will here speak of a gold clasp of a round form, which I miidc for Pope Clement the Seventh, with which he fastened his mantle, and partly of the manner in which I worked it. This clasp was of the diameter ot a palm (three inches), and from its large size very difBcnlt to work, for in small works the material is more obedient to the hand. My labour in this was so much the greater, inasmuch as I was tied to certain jewels which were to be set in the compartments of it ; amongst them was a diamond, which had been bought at the price of 36,000 scudi (about 7000/.) Upon this most noble gem I adjusted a figure of our 'Heavenly Father,' seated, and giving with fitting dignity the benediction; the head and arms of which I had made quite round, the remainder being attached to the field. Around this figure I arranged more than one troo]) of angels ; of these some wound themselves round the borders of the robe, and some I arranged with skill amongst the other jewels I had to employ ; part of these cherubs I made in whole rehef, some in middle, and others in low relief, accordmg as I wished them to appear neai- or distant, following in this the rides of design and perspective. Having made the model of the exact size of the intended work, I took a sheet of gold, larger by a finger all round than it would be when finished, and commenced bulging it in the middle, striking it with small hammers on the face of an anvil; but on the inside I struck it with the point of the hammer, thus causing it to swell up very much in the middle ; and where I observed that it was too thick_ I worked with the punches on either side, till the piincipal figure, that of the 'Father,' began to assume a suitable form. In this way, little by little, using all sorts of punches, with patience and enthusiasm, I made the gold plate obedient to me, and in a few days I very nearly got the figure of the ' Father ' quite round. " AVliilst I was thus quietly working, in consequence of certain invidious persons belonging to this profession having said, to some familiars of the Pope, that I should not succeed with honour in this work, and that I was worldng in a manner very different from that of Caradosso,— both more dangerous and less beautifid,— the Pope sent "for me, and gently asked me if, after I had brought to him the model in wax, I had made any other? I therefore showed him how much I had up to that time done, to his very great content and picasm'c ; and he was pleased to favour me with words to this effect (speakhig, turned towards the many gentlemen who were around hiui, and, perhaps, some of them the same who had dune nie this evil turn), ' that I had greatly improved upon the model which I had already submitted to him.' His Hohness then inquired of me how I should manage to work out of the plate the little angels which were in the model, without spoiling that which I had already done? I replied that, in the same manner as I had relieved the figm-e of the 'Father,' I should be able to bring up those of the angels, that is to say, bulging little by little the gold plate with the punches on either side of it, till I had by degrees distributed the gold to where I found it was most requu-ed; tliat as there were some of them in very high relief, to bring them up to the required height I should have to treat them in the same manner as I had adopted in the figure of the ' Father,' but that aa the others were in less relief, I should not have so much difficulty with them, adding, that the greatest labour in working the above plate was in keeping the gold of an even thickness. When I had said this, his Holiness asked mo why I had not fol- lowed the method of Caradosso in working ; to which I said shortly, that that artificer, before he began to work, made a bronze cast, a method which appeared to me to cause greater difficulty and to consume more time ; that, had I been governed by his system, I should have been obhged to piece and join the work several times; thus exposing myself to the dangers which in soldering the fire is apt to cause; whereas in the method .which I had adopted in working the plate, such necessity would not occur, and 1 shoidd get forward more easily and with greater despatch. "Leaving his Holiness thus satisfied, 1 departed, and returning to operate on the above work, I commenced with my pimches relieving the cherubs, which were in number fifteen, without having to solder in my work any cracks whatever. After having joined the gold between the heads, arms, and legs of these little figures, I began detaching them from the field, and joining that part of the field which had been separated by the portions I had detached ; and I then with great skill soldered them, adopting the method before spoken of — that is to say, making the soldcrings with 'stopping.' When it occurs that works of so large a size have to be executed, the skilfnl artificer should be careful to put them into the fire as little as pos- sible, for the purpose of avoiding their being soiled by the solderings, for, should any enamelhngs be required, such soifings would iuti-rfcre with their clearness. For this reason I got into order all the splits, and all those parts that I had joined together, such as the arms, the legs, and the heads of the figures, and when properly arranged I soldered the whole work in one firing : \iorking thus, in four firings I managed to solder everything. The solderings being completed, I set myself to clean tliem care- fully, particularly those on the field, and when I saw that these were clean and quite e([ual in thickness, placing niy work on the pitch, I worked at it with the punches ; and as there were, as I have said, figiircs of infants in both high and low relief, and also another sort, on the field of the work, which had been wrought with only the large punches, I profiled the whole of them, and afterwai'ds taking my work from the pitch, I well roasted or tempered it in the fire; and replacing it on the pitch with its bottom up — that is to say, burying the figm-es in the pitch (having for this purpose rendered some of the latter some- what more soft than I had it at first), I commenced depressing with the small punches those cherubs which I had profiled from the face of the work, and forcing out somewhat more those which had to appear more forward than the others. Having done this, I took the work from the soft pitch and replaced it in the first or harder sort, thus always working it up to greater perfection. " There were, as I have said, several jewels to be set in this clasp. For this reason, I made a bottom with a hook or clasp, which fixed it to the papal cloak, and I worked it with various sorts of shells, masks, and other things, whicii I thought would add greater beauty to the work. This bottom plate I fixed on with screws, which held it most strongly, nor could it be seen how it had been joined. I afterwards enamelled the work in several places, particularly in the frieze which was aroimd it. Finally, I gave it the last finish in this manner : — To smooth down on all the parts which were represented as naked tlie marks of the punches, chisels, gravers, and files, which are used in such works, I provided several shps of stone, with points shaped like chisels. These should be four or five in number, and the chisel-like points shoidd diminish ni proportion. There is nothing which gives greater beauty to this kind of works than an excessively clean surface ; and this can only be obtained by means of certain stones. The result of their use is, that the surfaces left by the iron tools do not appear by any means so much coloured as before. I therefore, with these stones, called snake-stones, adding a httle well-pounded pumice, and using their points, levelled and cleaned the naked portions of the figures. In finishing the draperies with which they were clothed, I have xl FORMATIVE PROCESSES. been iii the Iwbit of making a tool from a very thiii aud Jiighly-tcnipcred piece of iron, whicii, when broken in half, provides on the broken surfaces a very fine grain. With these broken surfaces I worked upon the draperies, by striking the tool with a hammer weighing a little less tlian a couple of sciidi {two ounces) ; aud thus I gained the effect I desired. This method is called by goldsniitha graining (or giving texture). To give effect to the heavier di-aperies a small pointed iron tool (not broken) must be used. By hammering this upon these draperies, the appearance of a thicker material will be produced. This has the name of granulating. To mark the separation of the planes of the field, a thin and well-sharpened chisel miist be used, and with this they should be scored crossways, as otherwise they would not show at all well. This has the name of hatching, " After I had done these things, I placed the button in a well-cleaned glazed basin, and caused some young boys to make water thereon, the urine of these being warmer and purer than that of men. After this I commenced the colouring. The colour is composed of equal parts of verdigris and sal-ammoniac, very clean saltpetre being added, to the amount of a twentieth part of the two former. Tha whole of these I ground togetlier. They should, however, never be ground on either iron or bronze, but upon stone ; either porphyry or any other — porphyry, however, being the best. When well ground up, they should be put into a glazed porringer, and the couiposition diluted with wliite vinegar till it be of a consistency neither too liquid nor too solid. This composition I applied with a very fine hog-hair brush over the work equally, the thickness of the blade of a knife, I then liglited a fne with half-burnt charcoal — that is to say, charcoal which, having been previously used, had lost its power — and made the coals sufficiently level for tlie work to stand thereon. Having put the work on this fire, I took with the tongs sonic well-lighted coals, and applied them wherever I found the composition too thick, observing carefully that the verdigris burnt equally, and did not crack in the l)urning ; for there is a difference between causing it to burn and causing it to dry upon the work. Should this occur, a good colom- would not be produced ; moreover, it would be difficult to afterwards detacli it with the brushes. When the verdigris ia very nearly equally bm'nt, the work, thus dried and hot, should be taken from the fire and placed on a stone or wooden table, a clean basin being tm'ned over it, and there left till it be quite cold. It is then to be covered all over with the childi'en's urine (we have spoken of), contained in a clean glazed basin, and cleaned with hog's bristles. This ia the method to be followed when there is enamelling ; but works that are not enamelled may, as soon as the verdigris is burnt, be placed thus hot in the urine and then be finished. The above were the methods I adopted in this work ; and when I came to the setting the jewels in their places, I did not fail to do that with my best skill, by means of pins and screws, ti.ving the ground in this way as strongly as though it had been soldered. " I think it well here again to warn the artificer who may have to set large and small jewels together in such works, to see that they are arranged in his design with judgment, for it often happens that goldsmiths will adapt with great disproportion some large gem as an ornament to a small figure, thinking that the diflicidty arising from the largeness of the jewel will excuse them, as oceuiTcd in this same button ; for the Pope being resolved to have therein a figure of God the Father, many of the goldsmiths in their designs placed the great diamond directly in the breast of tlie figure, and as it was impossible to make the figure large in proportion to the gem, it resulted that there was but little grace in such an allocation. The Pope was sensible of this fault, for having looked at many models (mine was the last), he said to those masters that he would have wished the diamond not to have been so employed. In reply they said, that it would be difficult to arrange it otherwise. His Holiness making then a sign that I should approach and show my model, he saw that I had employed the diamond as a sort of seat, on which I had placed the ' Father.' So much did this niodel please him, that he at once consigned the work to me. Therefore (as I have said), do I advise the goldsmith liaving to set similar jewels, to be careful to observe good proportion and good design in his work. " There is also a practice in this art of gold-plate working of making small figures of the sl/,e of half a braccio (about one foot) or less, as may be requked, which I will illustrate by the means of an example, as I have hitherto done. At the time I was working at Rome, there was among the Cardinals a ]jious custom of keeping in theu" cabinets the image of the Blessed Jesus Christ on the cross, in size rather more than a span ; — the first which had been made were worked in gold with excellent design by Caradosso, for which he had received one hundred gold scudi a-piece. As I have done with regard to the medallions of sheet gold, I will now also do by treating first of Caradosso's method of executing these crucifixes, and then mentioning mine, which, for the reasons I shall give, I think easier and safer than his. When Caradosso had made his model the exact size of his intended figure (the legs being separated, that is to say, not laid over, as is customary in crucifixes,) and finished it as he wished, he cast it in bronze ; he then took a slieet of gold of a triangular shape, about two fingers larger all round than the model, this he placed on the bronze crucifix, and using small, but long wooden hammers, he continued beating till he gave it a form rather more than half relieved ; then, taking his punches and hammer, he carefully hammered it on either side, thus giving to his figure that rehef which he thought sufficient. Afterwards, with the same punches and hanmiers, he beat the rims which remained of the gold of the figme ; so that at last, in touching each other, the roundness of the head, body, arms, and legs, was formed ; he now filled it with stucco, and with his punches and hammer again went o\'er the whole, working up the chief muscles of each member of his figure with great feeling and skill. Removing it from the stucco he joined the gold togetlier carefully in the before-mentioned manner, leaving open a hole between the shoidders to enable him to take out the stucco ; he then gave the finish with his small chisels ; and when he was near to the last working which the figure had to receive, he gently laid the feet over each other. Such was the method followed by the above artificer. I only differ from him in this, — . that in such works I cannot countenance the adoption of bronze, it being in its nature most inimical to gold, aud causes it to break, introducing great difficulty into the work. I, however, by means of punches and various anvds (called by goltlsmiths snarling -irons,) with the skill and certainty acquired by long study in the art, contrived to complete my works without first casting in bronze ; by this method of mine I brought my work to completion much more quickly, and escaped from the fumes of the bronze, which, as I have said, stain the gold : in ail other points I adopted the system of Caradosso. " To show to my reader that I have not borrowed these practices fi'om other artificer, but have acquired them through my own industry and experience, by putting them to the test of execution, I will mention a work m plate I had to execute for King Francis I. ; whieli, on account of its size (if in no other respect), is worthy of the notice I purpose making of it. This piece of plate, then, was a gold salt oi' an oval form, two-thirds of a braccio in length, and the fbst base of this oval w-as four fingers thick. The composition consisted principally of two figures, one representing Neptune, god of the sea, and the other Cybele, goddess ol the earth. On the side where Neptune was I figured the bosom of the ocean, upon wliich was a shell, and the god FORMATIVE PROCESSES. xli seiitcd triuiiipliantly tlicrcon, drawn hy four uiai'iiio liui'scs, his loft luuul holding his trident, and leaning with his right arm ujxin a boat, which was to contain the salt, with several skimiishes of marine monsters around; and in the waves on which the boat was placed were seen fishes swimming about. This figiu-c was made from a sheet of gold quite round, and rather larger than half a braccio, by means of punches and hammers, as before mentioned. Upon the other side of the salt was standing, on the shore, the figm-e of a woman of the same size, metal, and roundness, representing the Earth, whose legs touched those of Neptune, one being extended, the other gathered up, but crossed, my intention being by this attitude to represent the plain and the mountain. In her left hand she held an Ionic temple ricldy ornamented, which served to contain pepper, and in her right a cornucopia with all its beautiful appm-tenances, Upon the earth or shore on which she was placed wei'e leaves and flowers, also little animals skirmishing and playing together : both the land and the sea bad thus each its own appropriate life and ornaments. Besides these, in tin- thickness of the oval were eight niches ; the first four contained Spring, Summer, Autumn, and Winter : in the remainder M-cre Dawn, Midtlay, Twilight, and Night. Thus did I ornament these niches, the angles of which, as well as several other places in the work, were interlaced with little bands or threads of ebony, the contrast of their black colour adding much to the beauty of the whole. Lastly, I placed this salt upon four little ivory balls, which being half-sunk in their boxes, enabled the machhie, by their rolling about, to be moved backwards and forwards easily. Several parts of this piece were enamelled, such as the fniit, leaves, flowers, trunks of trees, and all the waves of the sea, according as our art requires and suggests. " Wlien I had finished this salt, and fixed a day for taking it to the king, an event happened, the relation of which wOl serve to conclude our treatise, and also will show to skilful men that, though subject to the scheming of envious and malicious persons, they have, in fact, no cause to fear their evil designs. A certain Monsignore, whose name I will not mention, envying, for what cause I know not, my s\iccess and the honoiu- shown me, devised a plot against me worthy of his own weak mind. On the day the king was to look at this work of mine, this gentleman tried, by distracting his majesty, to prevent him from so examining my work as to perceive the extreme pains I had taken ; — even to such an extent are vile minds lu-ged by malignity. The day before that on which I was to go before the king, this sagacious old man, knomng of the arrangement, paid me a visit, showing me, at the same time, some antique bronze figures ; small, but really good : having asked rue what I thought of them, I praised them highly as they deserved, oSering to give for them a sum which 1 cannot now remember : he left ine apjjarently quite satisfied. But at the time that I was exhibiting niy salt to the king, he, according to his intention, being also there, and feigning to be present by chance, presented the before-mentioned antiques to his majesty, adding the testimony I had borne as to their perfection and value. Having examined and somewhat praised them, the good king, tiu-ning to my work, said, ' We ought to be not a little grateful to the artificers of our own time, when they also can place before us objects of their own, not less beautiful than these antiques." Having said this, he dismissed me, praised and rewarded beyond ray deserts. Such was the result of the cunning of this hateful old man, who aftemards paid me a visit, making an excuse for disturbing me with the bronzes, by saying, that it was quite by chance he was that day with the king, ha\dng sometime back destined them for his majesty. I, however, pretended not to be aware of the action he had committed, which was done merely that these figures should be put into comparison with my salt. It is, however, time to conclude this treatise, and to commence tliat on the beautiful art of intaglio." X.— THE ART OF DIE-SINKING (AS PRACTISED BY CELLINI IN THE MAKING OF CARDINALS' SEALS), CONTAINING ALSO HIS METHOD OF SAND-CASTING. We translate the following particidars from the sixth chapter of CeUini's interesting work : — " In the art of making Cardinals' seals no one has shown greater perfection than Master Lautizio, a goldsmith of Prnigia, who worked at Rome in the year 15^5 — ^the making of dies for the stamps of the cardinals being his only occupation. These seals arc made about the size of the hand of a child ten years of age, and have the shape of an almond, the title of Cardinal being indicated by a composition of figures, and their family arms cut in intaglio. The price Lautizio received for each amounted to 100 scudi. " I will now, according to the custom 1 have adopted, first speak of some works of this descri[)tion which I have executed, and then of the method of producmg them, particularly describing that followed by Lautizio. In a seal I was commissioned to make for Ercole Gonzaga, cardinal of Mantua, I engi-aved the Ascension of Our Lady, with the Twelve Apostles, that being his title. Another, richer in the number of its figures, whicli I made for Ipolito da Este, cardinal of Ferrara, and brother of Duke Ercole, I euirraved « ith a St. Ambrogio on horseback, holding a scom'ge in his hand, with which he is driving away the perverse Arian crowd ; and aa St. John the Baptist also formed part of his title, in the adjuiiiiiig compartment (having made a division lengthwise on the seal) I placed St. John preaching in the wUderness. For the Mautuan seal I received 200 ducats, and for that of Ferrara 300 were paid me. " In the execution of these seals the artificer should, in the first place, taking a black stone with a flat face, draw on it the design which the seal has to bear, and then, with white and somewhat hard wax, ho shoidd model the relief which he desires the sejd to produce in stamping. When he has well finished the wax model, he should take some bm-nt chalk or plaster (volterano, or other chalk, provided it be fine), and, having oiled the wax design (using for this purpose a clean miniver brush, dipped in olive oil, being careful not to lay on too much, as that would clog the model and prevent the plaster from entering into the more delicate parts), he should make a boundary round it with fresh and soft earth, about two fingers in height, and then pour on the liquid plaster, painting it as it were upon the wax with a largish miniver brush. When well worked in, it should be left to set, and, having become firm, it may be detached from the was, which will not be damaged in the least, as, from the intaglio having to be used as a stamp, tlicre can be no under-cuttings. The mould should then be cleaned from the irregularities which will exist on its edges. " Having now arrived at the time for casting, aa there are two methods of doing this — and, in silver casting, one easier than the other, both being good — we will speak of each of them, so that the ai'tificer may adopt whichever may be most to his mind; advising him to make trial of both one and the other, as some improvetuent may suggest itself, as occurs continually in the practice of the goldsmith's art. The first method, that followed by Lautizio, wc now treat of, in which the sort of earth used xlii rORMATlVE PllOCESSES. by brass- workers and stud-makers, who cast the trappings for mules and horses, is «mployed. This earth is made of volcanic sand, an excellent specimen of which I saw in the river Seine at Paris. On account of its good qnaUties, I think it worthy of notice. It is found in au island called La Sainte Chapelle, in the middle of the Seine, is excessively fine, and has the quality, so different from other sands, of not drying, as occurs so much w-itb them, when used for the purpose of casting in boxes. With this sand, gold, silver, brass, and other metals can be cast. But, before we speak of the other earths fit for moulding, it will be better to demonstrate the manner of moidding the plaster for casting the seal. "Havino' the damped earth in order, and the plaster being made quite clean, it should be dusted over with some very fine charcoal dust, or it may be smoked with the flame of a candle or lamp. Eilber of the metliods is good, and being so well known, we iwcd not speak further of them. When the plaster cast has been dusted or smoked, it should be moulded in the boxes, which ouo-ht to be large and strong enough to bind it. This being done, that portion in which the figures are moulded should be well dried (we are now speaking of Italian sand, not that of the Seine, which we mentioned lately), and a cake of dough shoidd be made of the shape and thickness of the proposed metal, whatever it may be ; the chalk mould should be smoked in the flame of a candle, the dough cake placed thereon, and then also the other box, wliicli will have been ready baked and dried. This must now be filled with the same damp earth, which umst be done with skill, so as not to break the dried portion, in which the figures have been already moulded. The mould must be opened again, and the dough cake removed, and the inmates should be made; also two vents on the underside— that is to say, they must both of them begin in the lower part and come out from the upper, near to the ingate. This part also being dried, both of them shoidd be slightly smoked with a candle, as we said before. When the mould is cold, the silver or other metal, being well melted, should be run into it, it having been found by experience that the metal flows into the mould better when cold than when hot. " There is another method, diflerent from the above, obsei-ved by Lautizio, which, as it is better in many points than that ■we have treated of, we shall describe for the benefit of the reader. Over the wax model of the subject of the seal a cast should be made with very fine plaster, in the manner we have before described. Some plaster should be taken separately, and as much in quantity as a third part of the plaster of the marrow of a sheep's horn, whicli should be well burnt, and botli one and the other should be well mashed up. To these should be added as much as a foiu-th part of the whole of tripoly, and the same quantity of pumice, and all the ingredients must be well pounded up together. When this has been done, as much -water (as will suffice for tlie materials) should be added, mixing it up into tlie form of a sauce, neither too thick nor too liquid. The plaster mould made ou the wax should be now oiled with a miniver bmsh and olive oil, and put by till dry — the plaster by its nature absorbing the oil, when it has of itself dried to such an extent as to be yet damp (for it should be neither too dry nor too moist), a wall of sand not less than two fingers high should be raised aromid it. This having been done, the corai)osition of plaster, horn, and tripoly before mentioned, should be poured on the oiled mould, and with a miniver brush be painted thereon, this being repeated till it has been laid two fingers or more thick ; so that at last a moidd is made of an almond shape, four fingers in thickness, which substance will enable the ingate to be cut, and wOl be suitable for casting in either silver or any other metal. Wlien the plaster is well dried, which it will be in about four hours, the two parts should be skilfully separated, so that no portion of the subject may be broken. It may be here mentioned, that it is nmch more easy to separate the simple plaster from the wax than it is to detach t!ic composition, the former being stiffer than the latter. "If it should happen that a head, an arm, or any other part of any of the figui-es, should remain in the hollows of the mould, two methods may be followed in repairing such an accident. Fu-stly, — if the artificer can extract the pieces, by taking some ground tripoly and using a miniver brush they can be readily joined together again ; for as the subject is in relief, it is easier to see where reparation is required than when it is in intaglio. The second method is to clean carefidly the plaster, and to oil it afresh, and then to lay on the composition in tha before-described manner, it being probable that though it failed in t!ie first trial it will come out on a second without any defect occurring. " I should wish that the prudent goldsmith would now pay attention to what I purpose saying. Let him make a model of wax of the exact size he intends the seal to be, and of the shape before described; this being made concave, and being placed on the design, let him be -careful to give to it that thickness which he intends the seal to have when cast. Then let him place the parapet of sand round the wax in the manner we have already mentioned, taking care that the ingate be made so long as his discretion may suggest, as it is a fact that when the ingate is long the work conies out better. Many trifles I might add which, however, I consider superfluous, inasmuch as I am speaking to men who are not inexperienced in this art ; I will, therefore, pass these things by. As I said before, the ingate of wax should be added to the model, and in the same manner the vents should be left, fixing them underneath, but causing them to come round the seal to the ingate above, not letting them, however, conmuniieate with it, so that they may breathe freely and answer their purpose. When the mould has arrived at this state it should be tied up with well-tempered iron or copper-wire, and be placed in the sun or other warm place, so that it may be well dried ; and afterwards it should be laid amongst some bricks put together in the form of a furnace, within which a fire shoidd be made for the purpose of making the wax run out. I would here mention that the wax must be pure, and unmixed with any other substance which might cause damage, because being pure, a beneficial eftect will be produced. When the wax shall have been thus removed, the fire should be skilfully increased round the mould, so as to bake it well ; !in improved result being thereby obtained. It must then be allowed to cool, as it receives the silver better when cold thnn whun wann, it being, however, understood that in this cold state there be no dampness. The mould is now ready, and the silver, being well melted, may be poured in ; and that it may not over-bm'ii, throw on it a little borax, and over that a liaudfid of well-gi'ound crust of wine-butts (or tartar). "When the cast is made, the mould should be untied and opened, or it should be put into water, which is a better plan, as thereby the silver is more readily detached. The cast shoidd now be freed from the ingate's and the vents, and by means of the file brought into shape. The seal being so far executed, it is customary to fix it in the stucco previously mentioned, and (placing before it the first cast in plaster, which was in intaglio) to work up the silver to the effect of the model with punches, gravers, and chisels ; thus completing the design of the seal, including the connexions of the figiu-es, theii- draperies, and all other parts of them : for the purpose of trying the effect, it is well to often mould the portion on which the artificer is working in black or other coloured wax.

" The ring of Ethelwiilf, hitherto cited as a proof of the talents of the Saxons in the ai't of enamel, appears to give them just claims to proficiency in the more difficult one of damascening. This ring, and another in the same room in the British Museum, has had the ground bearing the inscription incised like a champleve enamel ; silver cut out to the forms has tiien been beaten in, and the \yhole afterwards filed to a surface. But whilst the art was well-nigh forgotten in the West, the Arabs had obtained a great reputation for their beautiful productions. Thcophilus, who probably wrote in the first half of the thirteenth century, especially praises the Arabs for their talents in ornamenting the metals. The principal manufactories were situated in the various town iu Mesopotamia ; Moussoul or Mosul, however, on the Tigris, appears to have been the chief locality. The articles, which were principally bases or mirrors, made of fatten and other alloys of copper, and ornamented with silver, and sometimes with gold, were thence exported to Damascus, which being the most opulent town in the vicinity, and possessing the greatest amount of trade, by reason of its being the rendezvous of all the pilgrims from the north of Asia, on their way to Mecca, naturally received the largest share of those exports. It was also the nearest market for the Crusaders and Latin Christians, who forthwith gave the name of the emporium to the wares themselves. By this, it is not to be inferred altogether that Damascus had no manufactories of her own ; the contrary was no doubt the case, but still they must have been of a secondary nature compared with that of sword-blades, for which she was celebrated far and wide. " In the museum of the Louvre is preserved a most beautiful vase of Arab workmanship, called ' La Vase de Vincennes/ which St. Louis is reported to have brought to Trance with him on his retm-n from his ill-conducted and unfortunate crusade. It was probably a present from the Sultan of Damascus, as Joinviile mentions an embassy from that prince to the Erench king ; and from the inscription we learn that it was made by Mohammed, the son of Zin-Eddin. This vase has been ornamented in the fol- lowing manner; — The surface of the figure was cut away slightly in the middle, but much more so towards the edges, where it left a rabbet or undercutting. A thin piece of gold nr silver of the reqiured shape was then applied, and its edges forced into the above-mentioned under-cutting, and by this means effectually secured. There was another mode of proceeding, which, however, appears to have been less commonly used. The ground having been sunk by means of chiselling and engraving, the ornaments which were left in relief were pricked all over with a sharp-pointed instrument, and then the thin pieces of metal were fixed thereon by pressm-c. " Although the protracted residence of St. Louis in the East had, no doubt, a great influence upon architectural ornamentation in general, and on some branches of manufacture, yet it does not appear that this beautiful ai't was practised in Europe untQ at least two centuries after his epoch. At last the art was taken up, and finally secured to Europe at the commencement of the fifteenth centmy, by the cunning workmen of Venice and ililan. It is more than probable tliat the first-mentioned city took the initiative, by imitating the products of Oriental industry, and thereby, instead of importers, became the manufacturers. But very soon the capabilities of the art became better known, and Italy, which had been the first to introduce plate-armour, now perfected the invention by ornamenting it in the most beautiful and durable manner. This addition to its ornamental resources was particularly acceptable to Milan, then the chief mamifactory of armour, not only for Italy but for all Europe, and the extent to which it was applied to arms (both offensive and defensive) may be gatliered from the fact, that among the Italians damascening, and lavoro all' azzimina, were synonymous expressions. Not only armour, however, but various other articles, were ornamented with damascening by the industry of the Italian artists. These works upon iron were formed by roughening the whole siu-face of the metal with a fine graver or file. The ornaments, for the most part consisting of thin threads of gold, were then fixed by means of pressure ; the whole was afterwards burnished, which restored the ground, where not covered by the gold, to nearly its original polish. The shield belonging to the Queen, which her Majesty hberally contributed to the Mediaeval Exhibition at the Society of Arts from the Guard-room at Wuidsor, is another example of this mode of treatment ; but though we may well doubt whether it was executed by the immortal Benvenuto Cellini, as the figiu-es betray a decided French style, yet it is probable that the dama- scening might have been executed by some Italian artist at the French court. It was not until a century later tliat France began to excel in this art ; when the productions of Cursinet added additional lustre to the reign of Henri Quatre. " But to return to the process of manufacture. When the pattern had many solid parts and few or no thin lines, only the surfaces covered by those parts were roughened and the ornaments applied as before ; the labour of burnishing was thus saved. " Very often in this case the gold ornaments were in relief, and would of course require chasing after the pressLU'e necessary to make them adhere. There was yet another way which was occasionally used. It consisted in pricking the outline only of the ornaments in such a manner as to make little raised teeth, to ^vhich the gold was then fixed by pressure. When, however, the ground was a less intractable material than iron, the same process was employed which we have described as obtaining among the Arabs, and which process there can be no doubt came from the East through the Venetians. This was also occasionally used even on iron, especially in situations liable to wear, as sword-blades, for example, where the ornamental pattern requires to be on the same surface with the ground. It is to this branch of the art that Cellini alludes in an ewly part of his Lffe, where he says : — ' Soon afterwards I met with some Turkish daggers, the handles of which ivere of iron, as well as the blades, and even the scabbards were of that metal. On these were engraved several fine foliages in the Turkish taste, most beautifully filled up with gold.' He then imitated them, and observes, ' My performances were much finer and more durable than the Tiu-kish, for several reasons; one was, that I made a much deeper incision in the steel than is generally practised in Turkish works.' The other reason was, that he used a different kind of foliage, the Turks employing only the chicory leaves; whereas the vine and ivy were the favom-ites with the Lombards, whilst the Romans, true to their antique traditions, principally made use of the acanthus. He also talks of some antique iron rings being discovered inlaid with gold, which he also copied, and for which copies he received as much as forty crowns a-piece. In his imitations of them, he says, he ' wrought some of these little rings, but made them of well-tempered steel, and then cut and inlaid them with gold.' " m DECORATIVE PROCESSES.

HISTORY-INTRODUCTION. When we reflect on the multifarious uses to which metals are applicable in a highly- cultivated state of society, and what important agents of civilization they have been, — as tools — as originating barter — as serving as the medium by which trade was made to take the place of barter — as associating themselves with the first approximation to ideal beauty in barbaric richness, and as gradually becoming from day to day more indis- pensable to all, fi'om the highest to the lowest, we could not but look upon any history, which should actually record the modifications of their use, as one in which was written a memoir of the social progress of the whole human race. Such a history it is neither within our power nor our purpose to offer ; our aim being to trace only those fluctuations of practice which connect themselves with the cultivation of a sentiment of beauty, and which are based upon the imperative law of perpetual motion, prescribing eternal change as the primary condition of a transitional state of existence. In this imperfect record we shall endeavour to apportion the amount of obsei'vation allotted to each period, by a scale of affinities to what we conceive to be the legitimate scope of artistic metal-work in the present generation, rather than by the archEeological interest of the subject alone ; and thus, ^vhile the traditions of the Italian "bottega" will be plentiful, our record of the works of the archaic and classical ages will be reduced to the narrowest possible compass. In the present chapter, which may be regarded as simply introductory to our main purpose, we shall pass rapidly in review the circumstances which led to the ultimate practice of the art of metal-work in the four principal countries of Europe, — Italy, France, Germany, and England. In thus adverting to national importance in connexion with this subject, we cannot but express our regret at being unable to furnish a proper amount of information respecting the metal-work of Spain; but little has been written on the subject, and we have as yet had no opportunity of studying in situ. Should circumstances, however, "convene," we may hope at some future day to be enabled to supply this Iiiattis, valde deflendvs. The patriarchal and archaic ages are involved in so nebulous an atmosphere, that the keenest eye can scarcely seize the instant at which vapour condenses into substance, and realities take the place of "myths;" and therefore it is that any reference to the legends concerning Tubal Cain, Hepheestion, and Dadalus — the far-famed demigods of metal-work mythology — can serve to but little purpose in the present investigation, excepting to demonstrate the extreme antiquity of the manufacture of metals. From the description of the riches of Abraham in gold and silver, the presents of jewellery offered by his servant to Rebecca at the well, the silver cup given by Joseph to his brother, and the ornaments taken from the Egyptians by the Israelites, we are fidly prepared to meet, on such an occasion as the construction of the Tabernacle, with a description of works, indicating a long-continued and fully-developed practice of the arts of metallurgy. The extreme antiquity of molten and graven images, iron tools, beaten work, brazen vessels, metal mirrors, iron beds, and beautiful jewelleiy, may be demonstrated from the writings of Moses alone. As if in corroboration of that portion of the great lawgiver's narrative which relates to Egypt, we find, in every European collection of any importance, ample confirmation of his account, in the material evidence they offer of the perfect acquaintance of the Egyptians with the most elaborate processes of metal-work. The commercial relations of Phcenicia— the country to which the invention of glass is traditionally ascribed— spread, we have little doubt, a barbaric species of enamel, not oidy throughout the countries having seaboards on the Mediterranean, but even in those of the north of Europe and of Asia ; and we need not, therefore, be 2 HISTORY— INTRODUCTION. surprised to find that learned- Egypt was acquainted with almost every variety of the art of glass-making and enamel at the earliest period. In the Britisti Museum, several necklaces may be seen formed of small orna- ments made in gold filagree, and filled in with precious stones, and what appear to be pastes, wrought and vitrified by processes corresponding with those subsequently made use of by the Byzantines and ancient Irish. In speaking of the metal-work of the Assyrians, Mr. Layard remarks, that "their earrings, necklaces, armlets, and bracelets, were all of the most elegant forms. The clasps and ends of the bracelets were frequently in the shape of the heads of rams and bulls, resembling our modem jewellery. The earrings have generally on the later monuments, particularly in the bas-reliefs of Khorsabad, the form of a cross. In their arms, the Assyrians rivalled even the Greeks in elegance of design. Ornaments, in the form of the heads of animals — chiefly the lion, bull, and ram — were very generally introduced, even in parts of the chariot, the harness of the horses, and domestic furniture." In this respect the Assyrians resembled the Egyptians. Their tables, thrones, and couches, were made both of metal and wood, and, probably, inlaid with ivory. We learn from Herodotus, that those in the temple of Belus were of sohd gold. From the difi'erence in the extent and richness of the work executed in the fitting up of the tabernacle and the temple of Solomon, we learn how much the art of metal-working had advanced during the interval between those two events. The casting and graving of the molten sea, thirty cubits in circumference, would be no mean performance in the present day. For the elaboration of the works of the Tabernacle, Providence had endowed one of the sons of the tribe of Dan with wisdom, understanding, and knowledge, " to devise curious works, to work in gold, in silver, and in brass." It is an interesting coincidence that the mother of the prince of workmen, sent to Solomon by Hiram, king of Tyre, was one of the daughters of the same tribe. We may imagine what the glories of the court of Jerusalem must have been, when we are told that " all King Solomon's drinking-vessels were of gold ; and all the vessels of the house of the forest of Lebanon were of pure gold : none were of silver ; it was nothino- accounted of in the days of King Solomon." From passages in the book of Esther, in Herodotus, Diodorus Siculus, and Athenssus, we learn to realise the gorgeous luxury of Ahasuerus and his court; and on considering the pecnhar position obtained by Greece relatively to all other nations, and especially to Persia, we can wonder little at the traditions which have reached us of the extraordinary and almost fabulous beauty of the metal-work produced by a people whose philosophy was art, and whose art philosophy. In endeavouring to convey some idea of the details of this most glorious school of art-manufacture, we cannot do better than draw on the result of the researches of the learned Midler, whose work is now happily brought within the reach of all Enghsh readers through Mr. Leitch's translation. Speaking of ancient Greek art, it is observed, that "with regard to articles of metal — such as Hephrestus, the patron of all smiths, manufactured in the highest perfection — Homer celebrates cauldrons, goblets, tripods, cups, coats of mail, and shields, as partly of native and partly of foreign workmanship. Besides these, there are mentioned a great number of metallic and other shining articles, which it was the custom to dispose in such a way as to produce a striking effect. " On one of these works of art, the HephaL'stian shield of Achilles, Homer even describes large com- positions of numerous figures ; but the very extent and copiousness of such representations, and the little regard that is therein had to what is really susceptible of representation, almost completely preclude the idea that he describes human works of simUar compass. Here the mode of proceeding could have been no other than this, — the metal, after being softened and hammered into plates, was wrought with sharp instruments, and then fastened to the ground with nails, studs, or such-like." Restorations of the shield of Achilles have been many times attempted,— in the last century by Boivin and Caylus, in the present by Quatremere de Quincy ; and it is scarcely necessary to recall the most exquisite work of one of the noblest artists who has ever lived, the cAef-d'ceuvre of the immortal Flaxman. Working in vessels was brought to much perfection after the Homeric times by means of two great inven- tions. Firstly, that of casting freely in moulds, which is ascribed to a Samian master, Rhsecus son of Phileas, and his son Theodorus, and which was, no doubt, of great advantage to them in the making of goblets and vessels, in the fabrication of which those artists were distinguished: they appear to have flourished in the forty-fifth Olympiad; and, secondly, by means of the art of soldering, — a chemical junction of metals, in which Glaucus of Chios — a contemporary of Alyattes, and, probably, a scholar of the Samian brass-caster — acquired fame, and in like manner proved his skill by ingeniously-wrought vessels, especially the stand of a HISTORY— INTRODUCTION. 3 crater at Delphi.
