My object was from the first national ; but the suffrage of private individuals could do nothing in furtherance of views of this nature. It was from the Directors of the British Institution that I looked for that effective co-operation which alone could secure any general or important results. I conceived that enough had been made known to entitle it at least to some consideration ; and my expecta- tions were, that a specimen executed by some eminent artist would be called for. This hope has been disappointed. It is, however, yet possible; and in that case I should be ready to meet such an overture with all the requisite communi- cations. PREFACE* XI After thus bringing the powers of the process into full effect, I can scarcely doubt that a very general impression would be received corresponding with my own. What further plans might then be adopted, I cannot presume to advise; but the best that has occurred to me isjthis — that a Course of Lectures should be given by some Professor at the British Institution, or elsewhere, with examples and experiments illustrative of the theory and practice in all its details, and to which I should have much satisfaction in contributing every assistance in my power. April, 1820 . V . : • * V / 5 .• [ ' ' ' l 7 ' AN ACCOUNT A NEW PROCESS IN PAINTING. The slight accident of spilling some wax on a crayon drawing, sketched on the back of a book hound in rough calf leather*, first led me to engage in a train of experiments, the result of which I now offer to the attention of the public. On attempting to scrape off the wax, a glaze was produced, which exhibited the co- louring with that peculiarity of texture and surface which so generally distin- guishes works of the old masters. It also gave a depth and mellowness of tone In the Year 1807. B 2 rarely to be found in modern paintings, and served at once to show all the bril- liant effects that might be obtained, if the art of glazing crayons could be brought to a regular process. It seemed, how- ever, not absolutely impracticable; acci- dental effects discover possibilities which experiment may at last regulate into sys- tem, and this possibility determined me at least to make the attempt. The effect I had witnessed made an immediate but ineffaceable impression on my mind, that the resemblance it bore to the old masters was not merely casual or incidental, but that it had, in fact, dis- closed the real principle on which their hitherto unrivalled excellence in colour- ing was founded. Although the minute modes of process might for ever elude re- search, the principle, once ascertained. 3 and rendered effective, would open new paths to excellence, by which the high standard of ancient art might again be approached. The idea was irresistibly attractive, and from that moment my mind was intently directed to the accom- plishment of this object. Without any preconcerted plan, or knowledge to di- rect me in the management and selection of the materials I had to resort to, I pur- sued it for a length of time, as a light in the dark , and against difficulties and dis- couragements that few, less sanguinely impelled, could have withstood. After devoting the entire leisure of the last seven years to this undertaking, I have at length succeeded in bringing to a regu- lar process, a system of dry colouring *, * I have adopted the term dry colouring as com- prehending any mode of painting without a fluid vehicle. B 2 4 which, besides its external resemblance to the Venetian manner, bears such a close correspondence with all that dis- tinguishes this school from every other known mode of painting, that I confess it appears to me impossible entirely to reject so many concurring analogies. The pictures I venture to offer for in- spection * are executed on this plan ; but before they are critically examined, I must entreat they may be viewed with even more than the common indulgence given to amateur performances ; and this not from personal feeling, but the strong impression I have of its future importance creates an extreme solicitude, lest these imperfect specimens should draw forth * These specimens being wholly unfitted for pub- lic view, are necessarily reserved for the private inspection of artists and amateurs. 5 any hasty judgment, before its powers have been completely developed by the more masterly hand of a professor. That enviable freedom of touch which charac- terises the Venetian school, this process would almost gratuitously bestow, so far at least as depends on the dry colouring ; but combined as it ought to be with oil painting I have found it very difficult to execute any satisfactory specimen, having from long habits of experiment almost lost what little skill I formerly possessed in the management of oil colours. If, however, due allowance be made for these deficiencies, the general resemblance to the old masters is perhaps sufficiently shewn to give a foresight of what may be looked for hereafter, when abler pen- cils are employed. A well executed copy in dry colouring, from a picture of the Venetian school, would, I feel assured. give such an exact imitation of their manner, as might probably render it un- necessary to look for further proof that this was the basis of their system. It is well known that the common mode of oil painting never yet enabled a modern artist to copy a Venetian master with any success, and it may perhaps be re- garded as absolutely impossible by any process of fluid painting: there is a fleshiness and a richness in the carna- tions and draperies of their pictures, which, I am led to believe, could only be produced by dry colour. I venture to say this from the particu- lar opportunities I have had of marking the distinctions in these two modes of painting. Colour, when applied in a fluid state, be the vehicle what it may, oil, water, or size, will always tend to 7 hardness and opacity; the colour and the vehicle run into a smooth fluid mass ; and whether it is painted thin or laid on in a body, it completely coats its ground, filling up all the breaks and interstices, and presents to the eye a solid opaque surface, like plaster or sheik — The par- ticles of dry colour never perfectly col- lapse, but leave the surface open and por- ous, producing that species of roughness which, in painting, gives the effect of softness. This may be rendered more intelligible by bringing in contrast the light porous texture of a pumice stone, and the coated surface of a painted wain- scot. Fluid colour is also colder in its hues than dry. The external effects of fluid and dry painting being thus contradistinguished by hard and soft ; rough and smooth ; 8 cold and warm ; it seems to follow of course, that singly, neither the one nor the other can be regarded as sufficiently compendious to accomplish all the pur- poses of art ; and that it is only from their combined operations we may look for a complete system of imitation. The art of painting being founded on a just imitation of the forms, colours, and sub- stances of nature, essentially charac- terised by different degrees of solidity, warm and cold colours, acute lines, or undefined contours, demands a system variously and specifically adapted to the representation of these opposite charac- teristics. It appears that the Venetian masters employed both these modes of painting, from which resulted that nice discrimina- tion of nature which gives so much truth 9 to their imitations. On examining their pictures I have generally observed that the flesh, draperies, sky, and ground, ap- peared to be principally executed in dry colour, and that buildings, foliage, the sparkling lights of metals, gems, &c. ex- hibited the more sharp and distinct touch of the pencil. Oil colour is indeed so in- compatible with the essential characteris- tics of flesh, suppleness, and transpa- rency, that the touch of the pencil is rarely to be found in their carnations, except as it may have been employed in scumbling over the half tints, or where bold and forcible markings were requi- site to the general effect. The appearance of the surface corres- ponds with these surmises; where dry colour may be presumed, it leaves the surface quite level, (except where it is 10 particularly charged in the embodied lights) and without any outer coat or skin ; but the oil colour, when freely im- pasted, rises from the ground, and leaves the handling distinguishable to the touch by its sharp irregular projections. The strong lights thus rising in actual relievo from a retiring ground, usually prepared of a very dark shade, contributed power- fully to the force of their clair obscure ; to which also the manner of rounding in the dry colour, losing it by soft degrada- tions in the obscurity of the ground, gave a wonderful truth and harmony. Their half tints appear to be produced by the shade of the under colour, which not being covered with an opaque superfice (as in oil painting,) gives a shadowy tinge to the diminishing colours ; a trans- parent blueness, yet more delicate, was lastly given by the operation of scumb- 11 ling wherever the lights and shades wanted union. This gradual illumination of an ob- scure ground gives the real principle of the clair obscure, as it exists in nature. The absence of light leaves the earth like an undistinguishable plane of shade, which its returning rays softly tints, and gradually shapes out in all the varieties of form and colour. By thus imitating the simplicity of her operations, these great masters seemed to reign over na- ture. Each object rising from its ground by the simple irradiation of its local co- lour, appeared at once in perfect har- mony, and with a richness and bril- liancy impossible to be maintained where tints of light and shade are wrought and blended together. The opacity of oil colour, and the necessity of blending fluid painting, makes it ill adapted to 12 such a system of light and shade ; but dry colour always unites with its ground, and when lightly touched always leaves it in view. The manner of Bassan offers the most direct illustration of this system : his pre- dilection for dark grounds is invariable, and essential to his leading objects, spirit, and effect. His dragged touches, freely charged with colour, required a rough absorbent ground, such as is left by dry colour before it is glazed. Titian, re- garding carnation as his primary object, appears to have preferred grounds of a warmer tint, rich brown, inclining to yellow or red, which gave an extraor- dinary sweetness and mellowness to his tones. Whether or not this should be the long- sought mystery of Venetian colouring, 13 may perhaps for ever remain a question in dispute ; but the probability of the fact is much increased by various inci- dental analogies and resemblances, which, though less obvious, are not less precise. Venetian pictures are found, upon analysis, to have been incorporated by an anomalous mixture of oils, glues, water-gums, resins, &c. uniting the whole into one homogeneous mass, not separable from its ground, or liable to crack, and extremely flexible ; some- times however marked by irregularities, which render these advantages precari- ous, indicating a system open to varied modifications, according as judgment or necessity might direct * : while some have resisted the most powerful solvents. * Vide Sheldrake on Venetian painting. 14 others will not endure even the mildest process of picture cleaning. This more imperfect class has been found to con- sist of different layers of colour, easily separable by specific solution, acting on one without defacing or injuring the other. These peculiarities which have so long excited attention, in every parti- cular completely corresponds with all I have had an opportunity of observing in this process ; a correspondence however which requires to be explained rather by experiment than detail. The incorpo- ration of the colour is effected by the same irregular mixture of unctuous sub- stances. The choice of binders is dis- cretional, and any and all may be used in one picture without exposing it to the usual consequence of uncongenial mix- tures, cracking or separating from its 15 ground. A very different result would follow were they successively used as vehicles instead of hinders . I cannot attempt to account for it on scientific principles, but the fact has fallen under my observation from a variety of experi- ments, that a body of colour painted dry, will, even when highly varnished, endure a strong heat, without cracking, blister- ing, or separating from its ground *. The regular process renders the body of colour “ capable of resisting the most powerful solvents but if after it has been firmly incorporated, retouchings should be necessary, it is then marked by all the uncertainties of imperfect Ve- netian pictures, and will on dissolution exhibit distinct layers of colour exactly * I conjecture this may arise from the absence of that skin or crust formed by the vehicle and the finer particles of the colour in fluid painting. 16 corresponding' with what has already been described. To account for this more clearly, it is necessary first to explain how impossible it would be to proceed with a crayon painting after the surface has lost that roughness necessary to imbibe and hold a body of dry colour. This roughness is lost when either it is saturated with colour, or when a glaze is formed by ac- cident or mismanagement ; there is then no other resource but to finish the pic- ture in oil, or to form a new surface of some gritty substance that will leave the under colour in view : an entire new body of colour may thus be laid on, but it will never thoroughly incorporate with the first ground ; and the same complex mixture of binders not being admissible under these circumstances, it is in conse- 17 quence much more delicate, yielding easily to solvents that have no power over the under colour. The specimen, No. 10, will clearly exemplify this, having entirely lost its last coat of colour in the operation of cleaning. That the Venetian painters occasion- ally resorted to similar expedients, ap- pears to me more than probable. There may be observed sometimes a gritty dust, like sand or pounded marble, sprinkled over particular parts of their pictures. I recollect one of Titian’s, in Lord Gros- venor’s collection, where this appearance was very conspicuous, and where evident signs of retouching, which could alone render it necessary, were also remark- able. Vasari, and other writers on the subject, repeatedly notice the extraordi- nary attention they paid to the prepara- c 18 tion of their grounds, which they are said to have considered of the highest import- ance. Dry colouring would render all this care necessary ; it would indeed be fruitless to begin a picture on a defective ground ; even in common crayon paint- ing it is very desirable that the material on which it is painted should receive the colour freely, but where glazing is in- tended, it is of tenfold importance. The varnish rendering some colours transpa- rent, and all in different degrees consi- derably thinner in body, requires the co- lour to be very freely charged, otherwise it will not bear itself out with sufficient effect against this diminution of volume ; but to accomplish this requires the ground to be of a peculiar texture, or prepared with extreme care. The superior lustre of their local co- 19 lours continually strikes the eye; it has led to the supposition that they were pos- sessed of some secret preparations now lost to the art. It seems, however, more probable that the secret was not to be found in the substances used, but in the mode of using them. The fine glazing colours which in oil painting the artist principally relies upon for the brilliancy of his local tints, will become thick and turbid if attempted to be laid on in a body. As, however, this defect does not arise from any original quality in the co- lour, but from the change it undergoes in its admixture with the vehicle ; the ab- sence of vehicle renders all these colours equally adapted to the purposes of solid painting, and when moulded into crayons enable the artist to paint in his local co- lours with that superior depth and bril- liancy they are calculated to bestow, c 2 20 The bright ruby and emerald green of Bassan, so long looked on with regret, may, I trust, by this means soon be re- stored to the art. There are, however, some Venetian pictures which appear to have been painted simply in clair obscure, and the local colours afterwards glazed in. The absorbent colouring is favourable to the reception of glazings, and the effect pleasing and harmonious ; but for force and depth of tone, their usual mode of richly embodying their local colours is far preferable. As I have never had an opportunity of examining any of the original memoirs on this subject, 1 am uncertain whether history may afford any further evidence of a more decisive character; but it seems 21 probable that hereafter there may be noted many slight circumstances and in- cidental remarks, which, when connected with the system I have attempted to de- velope, would give it powerful corrobora- tion. The account given of the Bassans is marked by a striking correspondence. Their mode of practice is described as being remarkable for expedition, facility, and cheapness : so much so, that they degraded the art into a mere trade. It was their custom to purchase old clothes of every description, table cloths, rem- nants of old silk, cloth, &c. upon which they painted their pictures, and in a few weeks or a few days brought them to the public market, selling them as common goods, valued by a per-centage on the original cost of the unwrought mate- rials *. * A practical knowledge of the process is neces- sary to make this correspondence perfectly clear. 22 In some memoirs relative to Titian, the author mentions being in his paint- ing-room while he was employed in blending with his finger the soft carna- tions of one of his figures, and describes with much enthusiasm the magical effects thus produced by this great artist. This fact may now, I think, be admitted among others, as a sort of collateral evidence warranting the supposition that Titian was actually rubbing in dry colour with his finger, as is commonly practised by crayon painters. It is true this mode of softening is sometimes resorted to in oil painting, but its opacity renders the effect invariably heavy, and the rich manner in which Titian’s carnations are varied and broken — the fleshy softness, and transpa- rency of his colouring — seems inconsistent with any such mode of practice. I have hitherto confined these observa- 23 tions to the Venetian School, because it presents the most obvious character of dry colouring, and because their acknow- ledged pre-eminence in this branch of the art renders the practice of these mas- ters the most important to be ascertained; but I cannot dismiss the idea that it was, more or less, the general practice of the age, variously modified and combined with the discoveries of Van Eyck. What these discoveries were, is left in much uncertainty. On the single authority of Vasari he was long believed to have been the original inventor of the art of paint- ing with colours ground in oil , till Mr. Raspe, in his essay on oil painting, and Mr. Horace Walpole, by various docu- ments, clearly proved it to have been an art in common use among house painters, and some artists in England and other parts of Europe, as early as the 12th 24 century ; a fact which entirely negatives the account given by Vasari, as it has hitherto been understood that this disco- very was first made by Van Eyck in the year 1410. It seems, however, indispu- table that Van Eyck had made some very important improvements in the art, which caused great sensation among all his co- temporary artists : some details, inter- spersed in the lives of the painters, will abundantly prove it, and before I venture to pursue the conjectures that suggest themselves, I shall present a few extracts from the lives of those painters most im- mediately connected with the first intro- duction of oil painting into Italy. In the life of Antonella da Messina is the following account : “ Some of Van “ Eyck’s pictures, exquisitely finished, “ having been brought from Flanders 25 “ to Alphonso, King of Naples, were “ beheld with astonishment, and par- “ ticularly by Antonella, who was so “ strongly affected by the wonderful “ effects produced by the new discovery, “ that he immediately determined to “ visit Flanders, and learn, if possible, “ an art that appeared so extraordinary. “ He went and recommended himself so “ effectually to Van Eyck, by his affa- “ bility and ingenuity, as well as by a “ present of some fine Italian designs, “ that Van Eyck unveiled to him the “ whole mystery, and Antonella in a “ short time became almost as eminent “ as his instructor. From a principle “ of gratitude he continued in Flanders “ as long as Van Eyck lived, but after “ his death Antonella settled at Venice, “ where he painted several pictures in “ oil that gained him general approba- 26 “ tion. He communicated the secret to a painter named Domenico, from “ whom Andrea del Castagno after- “ wards obtained the knowledge of it, “ and from him the art of painting in “ oil gradually became known and “ practised through all Italy.” Andrea del Castagno : “ He painted “ on ly in distemper and fresco, with a “ manner of colouring that was not “ very agreeable, being rather dry and “ hard, till he learned the secret of “ painting in oil from Domenico Vene* “ tiano, who had derived his knowledge “ °f that new discovery from Antonella “ da Messina. Andrea was the first of ’ “ the Florentine artists who painted in “ oil ; but though he was in the highest “ degree indebted to Domenico for dis- “ closing the secret, yet he secretly en- 27 “ vied the merit of the man who taught “ him the art ; and partly that he might “ preserve the secret of painting in oil “ from any other artists, and because he ** observed the works of Domenico abun- “ dantly more commended than his own, “ he determined to assassinate his friend “ and benefactor. He executed his de- “ sign with the utmost ingratitude and (C treachery (for Domenico at that time tf lived with him, and painted in part- (€ nership with him) : he assassinated fi him at a corner of a street, so secretly, “ that he escaped, unobserved and un- suspected, to his own house, where he u composedly sat down to work, and thither Domenico was soon after con- ft veyed, to die in the arms of his mur- “ derer. The real author of so inhu- “ man a transaction was never disco- “ vered till Andrea, through remorse of 28 “ conscience, disclosed it on his death- “ bed. He finished several consider- “ able works at Florence, by which he “ gained great riches, and as great a “ reputation ; but when his villainous “ misconduct became public, his name “ was ever after held in the utmost “ detestation. His most celebrated work “ is the execution of the conspirators “ against the house of Medici .” Giacopo Bellini : “ The secret of “ painting in oil was communicated to “ him by Domenico and Andrea del “ Castagno; and this important disco- “ very he explained to his sons Gentile “ and Giovanni, who had sufficient skill “ to apply it in such a manner as to “ make them considerable in their time, “ and memorable to posterity.” 29 Gentile Bellini : “ He was the “ eldest son of Giacopo Bellini, born at “ Venice in 1421, and instructed by his “ father in the art of painting in dis- “ temper as well as oil.” “ Giovanni Bellini was born at “ Venice 1422, the son of Giacopo and “ brother of Gentile ; but he surpassed “ them both in every branch of the art, u and is accounted the founder of the “ Venetian School, by introducing the “ practice of painting in oil, and teach- “ ing his disciples to paint after nature. “ Before he knew how to manage oil “ colours, his painting appeared dry, but “ afterwards he acquired more softness “ in his pencilling, shewed a much cc greater propriety of colours, and had “ something of harmony ; though still 30 “ he retained too much of what ap- “ peared dry and hard.” “ The school of Giovanni Bellini “ produced two memorable disciples, “ Titian and Giorgione, who brought “ the art of colouring to its highest per- “ fection ; and by observing the works “ of those famous artists, Bellini im- “ proved his own manner very consi- “ derably ; so that in his latter pictures “ the colouring is much better, and the “ airs of his heads are noble, although “ his design is a little gothic, and his ** attitudes not well chosen These details furnish the facts that Van Eyck was the original inventor of oil painting, and that from him it was * Vide Pilkingtorfa Dictionary. 31 transmitted, in direct descent, to the ce- lebrated school of Venice. It also ap- pears to have been a secret known only to one or two individuals by successive communication, w T hich, in order to make exclusively his own, tempted Andrea del Castagno to the cruel act of perfidy above related : thus giving dreadful tes- timony to its importance. How then can we reconcile this to the authenti- cated documents furnished by Mr. Raspe and Mr. Horace Walpole, which prove not only that it was not a secret, but that it was an art very commonly practised during the two preceding centuries, and certainly not originating with Van Eyck. Evidence so absolute, and yet so contra- dictory, renders it impossible to come to any satisfactory conclusion, if it relate precisely to one and the same thing ; but are we sure that Vasari, by the general 32 term oil painting, meant to restrict its application to the simple process of paint- ing with colours ground in oil , as unques- tionably is intended by Mr. Raspe, or did he apply it indiscriminately to every mode of painting where oil or oil colours were used ? If so, may he not have been per- fectly correct in ascribing to Van Eyck the new discovery which in the language of the day was certainly called oil paint- ing, but which in all probability differed essentially from the oil painting of the present time. It being notorious that the system then in use was originally derived from Van Eyck, Vasari might naturally sup- pose him to have been the first and sole inventor of it ; and knowing nothing that could contradict this supposition, he stated it as a fact, without giving the 33 subject that careful examination so requi- site in all historic details. That he was not in full possession of his subject appears evident, from the striking inaccuracies observable in his attempted explanation of Van Eyck’s first discovery : he states, “ that John “ Van Eyck, when he painted in dis- “ temper, and had tried many experi- “ ments of varnishes, having once taken “ great pains in finishing a picture on “ boards, varnished it, and put it to “ dry in the sun as usual, but the heat “ being too violent, or the boards too “ carelessly joined or seasoned, he had “ the mortification to see that his boards “ split asunder : whereupon consider- “ ing the damage he had suffered by “ the sun, he thought of some means “ to prevent such accidents for the fu- D 34 “ ture ; and tired and disgusted alike “ with distemper painting and varnish- “ ing, he endeavoured to make a var- “ nish that would dry by itself, without “ sunshine. After many trials of vari- “ ous substances, pure or mixed, he “ found at last that linseed and nut oil “ dried better than any other. These, “ therefore, he boiled with other mix- “ tures, and thus he produced that var- “ nish which he and other artists had “ been desirous of so long. He tried “ many other things, and observed that “ the mixing the colours with these oils “ gave them a great strength, and when " dry they were proof against water, “ and had a brightness and lustre of “ their own without being in want of any varnish : what he most won- “ dered at was, that they united and “ worked better than colours in dis- 35 “ temper.” He adds, “ although such “ paintings had that strong smell about *< them which fresh oil colours produce, “ and though for that reason it seemed “ a very easy matter to find them out, “ nevertheless it remained a secret dur- “ ing many years * Raspe, page 17. Van Mander repeats Vasari with a few variations : according to his account, John Van Eyck was so excellent a chymist that “ he discovered a method of varnishing his dis- “ temper colours with a varnish that was made of “ some oils, which was very pleasing, on account of “ the gloss and lustre it gave them. Many artists “ of Italy had vainly attempted to find out that “ secret, but they never hit on the true method. “ It happened once that John, having, in his usual “ manner, highly finished one of his pictures on “ boards, and having varnished it with his new in- ** vented varnish, exposed it to dry in the sun ; but (i whether the boards were not well joined, or whe- “ ther the sun was too violent, the boards split “ asunder and opened in the junctures. John saw “ with concern that his work was spoiled, and re- “ solved to contrive something against future ac- “ cidents of the same kind. Having been in that D 2 It is difficult to assign any precise meaning to many passages in this very confused detail ; we may however gather “ manner disgusted with distemper painting and “ varnishing, he thought of a varnish that might “ dry without sun-shine ; and having tried many “ oils and substances, he found that linseed and nut “ oil dried better than any other. He boiled them “ with some drugs, and produced the best varnish “ in the world. Ever bent on improvement, he “ found, after much enquiry, that colours mixed “ with these oils worked and dried extremely well, “ and when dry, would be water-proof. He ob- “ served likewise, that these oils would animate “ and give them a gloss and lustre without any “ further varnishing.” Again, speaking of Van Eyck’s picture sent to Alfonso of Naples, he says, “ when it arrived, the “ artists flocked together at Naples in the same “ manner as at other places, every one desirous of “ seeing this marvellous work ; and though the “ Italians looked at it very sharply, and tried it with “ the utmost attention, even putting their noses to “ it, and clearly perceiving the strong smell which “ it had from the mixture of the colours and the “ oils, nevertheless it remained a secret to them.” Vide Raspe, page 16 and 17. 37 from it that the main object of Van Eyck’s experiments was to find out some method of varnishing his distemper and water-colour paintings, and of giving them greater durability. This latter ob- ject he effectually accomplished by oil- ing the surface of his picture, which, when dry, and the oil completely ab- sorbed, would prepare a water-colour painting for any other operations of var- nishing or re-touching with oil colour. This is all we can collect of the dis- covery Vasari professes to describe; but such a mystery could not long have eluded the curiosity it excited. If we look to Van Eyck himself to assist con- jecture, it is still very difficult to form any decided opinion on the subject as to the nature or extent of his discoveries. His pictures though very brilliant are 38 evidently not painted with that freedom and vigour of touch that characterises the Venetian school ; and all that we can rest upon with certainty, is that his discoveries laid the foundation for those improvements which afterwards took place in the different schools of Italy. The early masters in oil colour are all marked by the same excellencies and defects — brilliancy of tone, with a dry elaborate manner of design ; but in the school of Bellini, and his celebrated dis- ciples Titian and Giorgione, the mecha- nism of art seemed at once to reach per- fection. The occasional use of chalks, or crude colour in lumps, might possibly first sug- gest to the artist the advantage of pre- paring his colours in the form of pencils 39 or crayons * ; but from whatever causes it may have originated, it is to this im- proved mechanism I cannot but ascribe that immediate liberation of the art from the littleness and poverty of the early manner. This improved method is first apparent in the works of Giorgione, where, unlike the monotonous smooth- ness of the early manner, we may ob- # I suspect the practice of painting in crayons is of very ancient date ; and it certainly may be traced up to the 13th or 14th century. It is however sin- gular that the historians of the art make no mention or allusion to it, at least in terms now understood as applicable to this particular process. I think it, however, very possible that the vocabulary of art may have varied in its usage, technical language being always arbitrary and independent of literary significations or derivations. The words pencil and crayon are examples of this irregularity in the ap- plication, and of an entire departure from there original or ordinary signification. The French word crayon means what in ordinary language we call a pencil , but, technically speaking, the word pencil means a painting brush. 40 serve the traces of handling preserved in rough and broken touches, and where the colouring boldly embodied announces at once the freedom of its execution. The habit of sketching their studies in colour is repeatedly noticed by Sir Joshua Reynolds, as peculiar to the Ve- netian school ; and, in his discourses, recommended to the students, under the idea that this practice was one of the principal causes of their so far excelling every other school in the art of colour- ing. In oil painting the advantages of such a practice are, however, counter- balanced by many material inconveni- ences ; but there is so little difference between sketching , or painting with coloured pencils, that it would be as easy to make out the design at once in colour, as to draw it with a pen or chalk 41 pencil. I conceive, therefore the prac- tice arose from the very construction of their instruments, but which doubtless would contribute to give that facility in the management and arrangement of colours for which they are so admirable. The sketch had all the richness and glow of the highest finish, and the co- louring all the freedom of the slightest sketch. It gave that fluency of style which at once told the thought as it rose in the painter’s mind, with all the animation and charms of a ready elo- quence. The art of painting thus acquired new facilities, which gave it considerable at- traction to all cotemporary genius. The power of embodying ideas was to be ob- tained without the severe toil of slow gradationary labour. A brilliant and 42 fascinating style, sometimes approaching to grandeur — always rich, beautiful, or splendid, gave that excitement to kin- dred powers, which impels to the exer- cise of art. The magnificent patronage of the Popes also added to its allure- ments; and thus the collective genius of the age received that peculiar direc- tion to the cultivation of the arts, which enriched Italy with the abundance of its treasures, and has long rendered this dis- tinguished period the wonder and admi- ration of succeeding generations. The decline of painting was rapid and decisive ; the cause may be found in comparing works of the 17th and 18th centuries, with the works of this memorable period. They announce un- equivocally the loss of that excellent mechanism which established a pre-emi- 43 nence that repressed even the hope of rivalry, leaving the modern artist en- gaged in a continual struggle against difficulty and imperfection *. I cannot however suppress the hope, that this lost art may yet be recovered. Let those who rule, accomplish the rest. Let na- tional rewards call forth national genius ; and then may we look with confidence to the fulfilment of those anxious wishes expressed by the late President, “ that * Mr. Northcote, in his life of Sir Joshua Rey- nolds, furnishes authority for this opinion ; he re- lates, “ that he was accidentally repeating to Sir “ Joshua some instructions in colouring he had “ heard given by an eminent painter at the Royal “ Academy; Sir Joshua replied, that this painter “ was undoubtedly a very sensible man, but by no “ means a good colourist, adding, that there was “ not a man on earth who had the least notion of “ colouring : we all of us, said he, have it equally to “ seek and to find out, as at present it is totally “ lost,’ > 44 “ the present age may vie in Arts with “ that of Leo the 10th, and that the “ dignity of the dying Art may be re- “ vived under the reign of George the “ Fourth.” * PART II. SUPPLEMENTARY DETAILS, EXPLANATORY OF THE PROCESS ; WITH MISCELLANEOUS OBSERVATIONS ON THE ARTS OF THE SIXTEENTH CENTURY. N W - Ttf PREFACE TO THE SUPPLEMENT. I have witli some difficulty attempted to methodize into system, a process which hitherto I have chiefly practised by de- sultory and irregular experiments. My anxiety to give the details the requisite clearness has led me into frequent repe- titions, that will I fear render them very tedious to ordinary readers ; but my ob- ject being simply to convey all the ne- cessary information, as fully and dis- tinctly as I could to those who might be desirous of trying the effects : I must on this rest my apology. 48 It is, however, not to be expected, that any written detail can at once put the Artist in possession of a system that is open to such a multiplicity of combina- tions, and which certainly requires not only good execution, but judgment and experience to regulate its application. I trust it is needless for me to explain that the observations I have ventured to make on the defects of modern art, have no reference whatever to the talents of its professors : they apply solely to the defects of process. To speak of cotem- poraries, even with praise, would be a matter of great delicacy ; but this I will say generally, that such is my faith in the native energy of English character and intellect ; that there is nothing with- in the compass of human ability I should not confidently look for, in any art, 49 science, or excellence to which the na- tional genius was fully and forcibly di- rected ; if unobstructed by moral or phy- sical impediments* The disjointed form in which the work appears, also calls for some apology. This has arisen from the continual vari- ation of circumstances, and the gra- dually increasing interest excited by the discovery, which at last induced me to offer to the Public, what originally was only intended to be privately circulated among my friends, and to add to it such explanations as may ultimately accom- plish the main object I have in view, — the promulgation and adoption of the process. I now offer it to the Public, in full E 50 confidence that the efforts of an indivi- dual will not be left unaided by a co- operating spirit of national feeling ; and that the hope, (presumptuous as it may appear,) which has for so many years animated my exertions, will finally be accomplished. But if disappointed in these expecta- tions, I shall have no cause to repine. I never can repent an undertaking that will still leave a large balance of plea- sure in the years of interest and amuse- ment it has afforded me ; and to borrow the words of an admired writer, I may truly say, that whatever may be the fate or reception of this discovery, it will owe its author nothing. In sickness or in health, whether of body or mind, I have found in these pursuits what can 51 alone alleviate the one, or give enjoy- ment to the other — occupation and en- gagement. June, 1821. E 2 ■ , DETAIL OF EXPERIMENTS. I had in the preceding pages abstained from entering on any detail of the pro- cess, under an impression that until the artist had acquired a little experience in the management of it, much disappoint- ment might occur, if attempted without the aid of personal instruction ; but be- ing advised that it would be more satis- factory to have as much as possible laid before the public, I shall endeavour to retrace, as well as I can recall them to my memory, the accidental circum- stances and observations which led me step by step to the accomplishment of my object. 54 In the year 1807 I went down into the country, unprovided with any materials for my then usual amusement — painting in oil. I soon began to feel very sensi- bly the want of this favorite occupation, and recollecting a set of Swiss crayons I had long thrown aside, I resorted to them ; but here again I was unprovided, having no blue drawing paper, such as is used for crayon painting. 1 was con- sidering what I could substitute, when casting my eyes on an old memorandum book, and observing the peculiar tex- ture of the rough calf leather in which it was bound, it appeared to me admira- bly adapted to my purpose, and I in- stantly began a coloured sketch on the back of this book. t t rwii f i.} t ' ) f I * ' i . . . ^ . # . ... , % . j The accidental selection of this mate- rial was singularly propitious and fertile of suggestions. The rich brown shade of the ground naturally led me to sketch in the figure with lights and middle tints only , leaving the ground for the shadows. The effect was strikingly pleasing and harmonious, and the ob- servations to which it gave rise laid the foundation for what I regard as one ot the most important principles of this process ; namely, to paint light upon shade and only light. In fact, to imi- tate nature as nature is made visible, and paint like the sun , — a system ot colouring which appears to me pecu- liarly, if not exclusively applicable to crayon painting, being, I should ima- gine, almost impracticable in oil paint- ing, where the gradations and union of the tints render blending to a certain degree indispensable. 56 The rough calf leather imbibed the colour with a degree of freedom and strength I had never before seen in crayon painting, which on the ordinary plan has a meagre chalky effect, that has long rendered it wholly unattrac- tive to the higher rank of Artists. I therefore no longer regretted the want of drawing paper, and determined in future to adopt some other material. While meditating on these improve- ments, by some accident which I can- not recall to my mind, I spilt some wax on the surface of the picture. I per- fectly recollect that it fell on some red drapery , which being, I conclude, paint- ed with Vermillion, did not lose its body , but was merely heightened in tone and lustre. The impression instantaneously 57 made on my mind, and the projects to which it gave rise, I have already de- scribed. Without further deliberation, and with a sort of childish eagerness, I immedi- ately melted a quantity of bee’s wax and poured it over the face of the pic- ture — with what success may be easily imagined. After spoiling by similar expedients all the rough calf bindings that fell in my way, I had to look out for some new material to paint upon. I tried canvass, linen, and cotton cloths. The latter I found far preferable to linen, which on account of the smoothness of its thread does not imbibe the colour so readily as cotton ; and from this time I have adopted common calico, as a ground the best adapted for general purposes; 58 its cheapness also is a recommendation for large sized pictures. My next trials were upon black ca- lico . The forcible effect of the lights on this ground completely confirmed me in my new system of light and shade. In- stead of pouring wax fortuitously on the surface, I was now enabled to apply it at the back of the picture, and then melt it into the body of colour by hold- ing it to the fire ; but the oily quality of the wax totally extinguished all the light tints, leaving only a few patches of reds and yellows visible. I then tried various other binders, and at last settled on gum arabick, or isinglass dis- solved in water, which on applying to the back of the picture fixed the crayons perfectly without disturbing or altering 59 the colour ; but finding, occasionally, much inconvenience from a sort of coarse woolliness of surface in the com- mon calico, to give a better grain I stiffened it with a little gum water be- fore I began to paint, which finally suggested the simple method I now usually practice in the first stage of the painting, of merely wetting the back of the picture with water, which dis- solving the gum fixes the crayons imme- diately. Here was one difficulty conquered, but there remained another, which for upwards of two years completely baffled every attempt to overcome, namely, the varnishing. Every picture I painted was subjected to some new trial, and invariably had the same fate. The mo- ment I applied the varnish, the painting 60 darkened and became nearly invisible, I however remarked that certain colours, such as vermillion, red lead, verditer, in short, all the metallic oxydes retained their full body and lustre, while the rest were either darkened or totally extin- guished. I endeavoured to ascertain the cause of this difference, and at length discovered that in the composition of crayons, flake white is cautiously exclud- ed, as it will infallibly turn black or grey on exposure to the atmosphere, if un- protected by oil or varnish ; and that instead of this white, (the one invari- ably used in oil painting,) the light tints are mixed up with whites pre- pared from calcareous earths, such as plaster of Paris, chalk, or whiting. The application of any oily or resin- ous mixture to whiles of this descrip- 6! lion reduces them to a semi-transparent substance, which renders them wholly inapplicable to oil painting. The re- medy was now obvious. My next grand step was to get some crayons prepared upon a plan better adapted to my purpose, though it was with some difficulty the colourman could be pre- vailed upon to substitute flake white in the mixture of the tints, he not being aware that they were intended to be var- nished *. * While retracing these circumstances an idea has occurred to me, which T think may assist to ex- plain the mystery that yet hangs on Van Eyck’s discovery. The facts we have before us in the different accounts that have been given of this mat- ter, shew that his first object was to varnish his dis- temper paintings, in which he totally failed ; but that afterwards he found out a method of varnish- ing his pictures with oil. It is quite clear that while he continued to employ the colours commonly used in distemper success would be impossible, the whites being similar to those used in the prepara- 62 This change at last opened a certain prospect of success. Still however many defects remained to be remedied. The colouring, though not destroyed, was considerably lowered in tone, and re- duced in body by the contractile effects of the varnish on the particles of dry colour. Being fixed with water binders only, it remained perfectly absorbent and took up too much varnish. To remedy this inconvenience, before the varnish was laid on I saturated the body of co- lour with wax, in the manner before de- scribed. The varnish was then better sustained, and the colouring stood out , , >0 nofii tion of crayons, and for the same reason ; and when at last he effected his purpose, his remedy must ne- cessarily have been what I have above described, namely, the substitution of metallic oxydes for the calcareous earths ; this probably laid the foundation for further improvements, and was finally applied by the Venetian painters to crayon painting’. 63 with a much stronger body. On further experience, however, I found many in- conveniences in the use of wax, which determined me to substitute linseed oil. This perfectly succeeded. After the pic- ture had been oiled, it might be retouched either with oil colour or crayons. If with the latter, this second painting stood out with far greater strength and brightness than the first ; but to fix it as had hitherto been done, at the back of the picture, now became impracticable. — When impregnated with oil it was no longer penetrable; and the necessity of fiuding out some method of fixing the crayons on the surface, obliged me to embark in further experiments. It would be tedious to detail the vari- ous expedients that occurred to me, ex- cept what at last led to my object. Lay- 64 \ ing the picture on the ground I fre- quently floated it with beer, isinglass, gum-water, &c. which always disturbed and defaced the colouring; but I re- marked that isinglass dissolved in gin, or weak solutions of resin in turpentine or spirits of wine, did not disturb the colour in the same degree. This observation was not neglected, and at length I as- certained that all proof spirits might, by a little mechanical contrivance*, be sprinkled on the surface without the least hazard of disturbing the colour This * A particular sort of brush which I had made up for this purpose, and which enables me to fix the picture with the most perfect accuracy. f This peculiarity I imagine may arise from the opposite tendencies of spirituous or aqueous fluids, the one to fly off, the other to keep together or conglobulate. The latter, therefore, lodge too long on the surface, and consequently deface the colour- ing ; but the fine subtle particles of spirituous fluids immediately diffuse and mingle with the loose grains of the dry colour. 65 discovery was most invaluable, as it en- abled me to fix in any stage of the painting, either with water or varnish binders. In the progress of the work it fre- quently happened that the surface lost that rough imbibing texture necessary to receive the touch of the crayon, owing to the interstices of the ground being choked up by colour or varnish ; hence arose a necessity for some contrivance that might artificially restore this sort of touch. For this purpose I frequently sifted pounded glass on the face of tiie picture, or applied a piece of black gauze * to any part I wished to re- * Here is another analogy with Venetian paint- ing. The late Mr. West once mentioned to me (with reference to this subject) that pieces of gauze P 66 touch ; but afterwards remarking the tenacious texture of flock paper, I ob- tained some loose flock, as it is prepared in powder for the paper manufacturers, and sifting it on the face of the picture, previously covered with a coat of oil varnish, it formed a second ground , that imbibed the colour with a degree of strength and richness I had never attained since my first accidental trial on the rough calf leather. Here ended all my difficulties. If disappointed in the effect of the picture after it was fully brought out by the varnish, I could at all times retouch and revive the colouring with increased bril- liancy. It may, however, easily be con- had frequently been found interposed between the two surfaces of the first and last painting in Vene- tian pictures. 67 ceived that this last layer of colour is much more liable to injury than the first, which being interwoven with the very threads of the cloth will never crack or separate from its ground ; and from the variety of binders admissible in the early stage of the process, the colour is so firmly incorporated as to resist the most powerful solvents *. Thus far I had invariably adhered to my original system of painting on dark grounds. The force and rapidity with which the general effect was produced rendered it highly attractive to me ; but the low tone of a picture, painted on this plan, does not generally please; I therefore occasionally varied it by pre- paring the ground of a middle tint, on * See Part I. page Pi, 14 ? 15, 16. F 2 68 which I carefully designed the figures, and shaded the picture to its full strength with pure water colour, so as to leave the whole subject indistinctly visible as in a sort of twilight. Thus prepared, I then lighted up the local colours with the bright free touches of the crayon, finally retouching the whole with oil colour where the lights required more force or sharpness, and afterwards scum- bled or glazed, as the tone of colouring required. But, whether I set out on a dark or a light ground, the principle on which I proceeded was precisely the same, namely, carefully to avoid all necessity for shadowing , either with oil colour or crayons ; for this reason that water colour best represents the negative qua- 69 lity of shade *. Nor did I allow myself to introduce any shadows but what the ground supplied. If I deviated from this plan, the picture was infallibly put out of harmony by the shades coming too forward, and appearing, if I may so express it, too embodied and tangible . Another desirable circumstance is, that the lights and shades being painted separately, the local colours preserve their full brilliancy and clearness, which blending light with shade must inevit- ably impair. It will be obvious on the least con- sideration, that such a system of clair obscure is applicable only to dry colour- ing ; that if attempted in oil colour the lights would appear harsh and spotty, * The difference between a painted cloth and a dyed cloth will explain this distinction. 70 from not being perfectly united with the shades of the ground. With crayons it is totally different; it is in fact scarcely possible to put the picture out of har- mony, so long as it is painted only with crayons, and with tints lighter than the ground . The process now combined the united powers and facilities of crayons, water-colour, and oil painting. By a judicious application of these varied resources, a perfect imitation of all that distinguishes the old from the modern schools of painting will be found at- tainable, and it is in this comprehen- sive form I recommend the process to be practically adopted, not as has been erroneously imagined by any single pro- cess of crayon painting. 71 Having given this general outline of the origin and progress of these experi- ments, I will now endeavour to detail with more precision some of the prac- tical operations of the process. • » > ' ■ . j ✓ i . ' . OF BINDERS. Mucilages and unctuous substances of every description are admissible in this process, provided they are good driers and not liable to crack. As they are acted upon by different solvents, I shall class them under two general heads, namely, varnish or oil binders, and water binders. OF VARNISH BINDERS. These are such as resist the action of aqueous fluids, but are soluble either in 74 spirits of wine, turpentine, or oil, and will melt if exposed to strong heat. Gum Sandarac — Dissolves in spirits of wine ; does not dissolve in turpentine or oil. Is of a very dry nature. Gum Mastic — Dissolves in spirits of wine, but more readily in turpentine. Is not so good a drier as gum Sandarac. Shell Lac and Seed Lac — Dissolve in spirits of wine ; resist turpentine and oil : are good driers and very strong binders, but are of too deep a colour to be used in the flesh tints. Common Rosin — Is a very cheap and useful binder, as it dissolves very readily with either spirits of wine, turpentine, or oil ; but as it is thus easily acted upon it should be used sparingly, and merely as a fixer. OF VARNISH BINDERS DISSOLVED IN OIL. As oil completely repels all aqueous fluids, and is in itself a powerful binder, of course those resinous substances that are dissolved in oil must necessarily be stronger binders than the common spirit varnishes. Gum Copal — The most powerful of all the binders, as it resists the action of spirits of wine or turpentine; and will only dissolve in oil when exposed to a very strong heat. Japan Gold Size — Composed of gum clemi, amber, asphaltum, &c. dissolved 76 in drying oil by strong heat, is therefore also a very powerful binder, and is use- ful in fixing the flock grounds, or as a glazing. OF OILS. It is of the utmost importance that the oils used in this process should be of the purest quality, otherwise a turbid foul- ness will rise to the surface of the picture, which will greatly impair the clearness and beauty of the colouring. Oils being liable to a regular process of fermentation, may by this means be rendered perfectly pure ; and I recom- mend that none should be used but such as have undergone this process of fermen- tation. This is, however, the business of the colourman. 77 In the course of time fat oils become waxy , and being of a tough nature, not brittle like gums or resins, leave the pic- ture very flexible, and when perfectly dry give strength and body to the colours. Common Drying Oil — Being prepared with sugar of lead, litharge, or other me- tallic oxydes, will always darken consi- derably ; and as it is the nature of all oils to rise to the surface, it should be used very cautiously. Linseed Oil boiled with Umber — Dries very well ; and when pure does not alter ; is not deleterious ; and I there- fore recommend it in preference to com- mon drying oil, when the darkness of the colour is not an objection. It is very useful mixed with japan gold size in fix- ing a flock ground. 78 Unboiled Linseed Oil — May be used very safely, but dries slowly. Nut Oil and Poppy Oil — The clearest in colour, but slow in drying. OF WAX. Wax — Dissolves in spirits of wine or turpentine ; softens with oil into a sort of butter ; melts easily when exposed to heat ; will not incorporate thoroughly with oil colour ; spoils the tooth of the surface, so as to render retouching with crayons almost impracticable. For these reasons I recommend that it should not be used in this process. But those who dislike the smell of oil, may perhaps dis- regard these objections. 79 OF WATER BINDERS. Binders of this class resist the action of rectified spirits, or oily fluids, or heat, but dissolve easily in water or weak spirits, such as gin, rum, and brandy. Isinglass — Dissolves in water or gin, but not in spirits of wine. Is a good drier, and being of a tough elastic nature leaves the cloth very flexible, and not liable to crack. i Common Glue — Precisely of the same nature, but the darkness of its colour makes it unfit for delicate toned pic- tures. Gum Arahick — Dissolves very readily 80 in water or rum. Is a good drier, but if used too strong will infallibly crack. Gum Tragacanth — Dissolves in hot water. Not liable to crack. All farinaceous substances, such as starch, paste, rice water, &c. &c. ought cautiously to be avoided, as I have in- variably found them subject to the defect of cracking. The opposition that exists between these two classes of binders and their varieties, if the artist rightly avails him- self of it, supplies a very powerful prin- ciple of incorporation. The colouring, first fixed with water binders, and then with oils and resins, wall withstand all the ordinary solvents. The water binders, when protected by oils and 8i fesins, effectually repel their natural solvent, water ; and are at the same time quite inaccessible to the common solvents of resinous substances, such as turpentine, heat, spirits of wine, &c. — Alter the application, or make it single , and the incorporation becomes very insecure as it is in common oil pictures. The colouring being simply incorporated with oil, easily dissolves in turpentine or spirits of wine, and would melt and rise in blisters on being exposed to heat. This principle of compound incor- poration, if once rightly understood, will be the best guide I can offer to regulate the application of the different binders as the work advances. It is also material to be attended to, as it effectually preserves that fine separa- G 82 lion of tints, or what is called breaking of the colours, observable in the old mas- ters. PREPARED MIXTURES FOR FIXING CRAYONS. VARNISH BINDERS. No. I. Common Rosin Binder . — Dis* solve two tea spoonsfull of pounded rosin in about half a pint of spirits of wine. No. 2. Ditto ditto . — Only, instead of spirits of wine, use turpentine. No. 3. Sandarack Binder . — Dissolve about a quarter of an ounce of gum sandarack in a pint of spirits of wine : place it near the fire, first taking out the cork or the bottle will burst. 83 No. 4. Seed Lac and Shell Lac . — Dis- solve any quantity of these gums in spirits of wine. When used for fixing, dilute well with spirits of wine. No. 5. Mastic Varnish, well diluted with turpentine. No. 6. Oil Binder . — Purified linseed oil, well diluted with turpentine. No. 7 . Mix a little of the rosin binder. No. 2. with the oil binder, No. 6. PREPARATION OP WATER BINDERS. No. 8. Isinglass . Dissolve isinglass in hot water. No. 9. Gum Arabic . — Dissolve in cold or hot water, g 2 84 No. 10. Ditto . — Dissolved in rum ; a little clarified honey may be added, to prevent cracking. No. 1 1 . Gin Glue . — Fill a phial bot- tle completely with isinglass, then pour in gin so as to cover the isinglass and nearly to fill the bottle. Boil it in a water bath till the isinglass is dissolved : keep it well corked. When you want to use it as a binder, melt it at the fire or in warm water (first taking out the cork,) and pour a little of it into about four times the quantity of gin. When the gin is good it will always fix the crayons on the surface , without blot- ting. It will also keep for years ; and is a very firm binder. No. 12. Mix strong size with megel- lup, or with copal varnish. This is very 85 useful in imitations of Rembrandt, and those masters who impasted their pic- tures with a powerful body of colour. OF GROUNDS. The most desirable qualities in a ground are, 1st. That it should have a good grain, and receive the touch of the crayon with freedom. 2d. That it should be flexible, and not liable to crack. 3d. That it should not be too soft or absorbent, so as to let the colours sink more than is unavoidable. 86 These qualities are, however, difficult to combine. The calico receives the co- lour freely, and is perfectly flexible ; but being so very soft and absorbent, the colouring does not stand out so well on this as on a prepared ground, and con- sequently requires many repaintings. — The artist will arrive more immediately at his effect in its full strength on a pre- pared ground, but it will not be equally flexible and secure against cracking. I shall distinguish the grounds as natural , artificial , and prepared grounds. OF NATURAL GROUNDS. Of this description are the different sorts of cloths, silks, leather, &c. that afford a grain or surface capable of 87 receiving the touch of the crayon. For large pictures I prefer calico to any other. It should be prepared as fol- lows : No. 1. Take a piece of common white calico, ot an even but flocky tex- ture, dip it in weak gum water or isin- glass ; wring it half dry, and strain it very tight on a wooden frame. When dry, colour it with raw umbre, or any colour that may be preferred, ground in water without any mixture of gum ; dry it at the fire, and the gum with which the cloth is stiffened will bind the colour sufficiently. Then rub it slightly with sand paper, to take off the superfluous woolliness of the surface and give it a better grain. Apply the rosin mixture, No. 1, at the back. The cloth being 88 impregnated both with gum and rosiu, the crayons may be fixed, either by spunging the back of the picture with water, or sprinkling the surface with spirits of wine. The water dissolves the gum, and spirits of wine the rosin, and that fixes the colour. So prepared, the shadows may be washed in with water colour, without disturbing the co- lour of the ground. No. 2. Prepare the calico according to the foregoing directions, but, instead of No. 1, impregnate the cloth with the oil mixture, No. 7, and let it dry and thoroughly harden before it is used. The oil will then assist to support the colours, and prevent them sinking into the unprimed cloth. The oil mixture being well diluted with turpentine, will 89 not repel the water colour so much as to prevent the picture being begun as usual by washing in the shadows. No. 3. White calico painted over with a thin mixture of chalk and size, and the rosin binder applied as usual. No. 4. The same, only the chalk mix- ture applied at the back of the cloth. No. 5. Impregnate the cloth first with isinglass, then with a mixture of drying oil, turpentine, and mastic varnish. Let it dry for some days, then colour it as you please : fix the ground with spirits of wine, then paint on it. For small high finished pictures India dimity, or rich silk, with a good grain, may occasionally be adopted. Rough 90 calf leather also. Vellum is of a beau- tiful texture for unvarnished crayons ; but in this process I have not found it answer, as it is altered by water or oil. Common drawing paper I would abso- lutely reject, as meagre and perishable. Papier machee might be rendered very useful, and I think it not unlikely that the old masters occasionally may have painted on grounds of this kind. Wood, when sawed and left rough, sometimes affords a very good grain. Copper would be desirable, if it could be made sufficiently rough by corrosion or filing. ARTIFICIAL GROUNDS. When the surface of the picture has lost its capacity or power of receiving the crayon, it will then be necessary to 91 resort to an artificial ground, prepared as follows : Dilute japan gold size with a little drying oil, and a small proportion of mas- tic varnish. Pass over the face of the picture with this mixture, then sift some dark coloured flock powder over it. — The flock will leave the painting in view, but it ought to remain some time to dry and harden before it is retouched. FLOCK GROUND ON PANNEL, OR ON A GILT GROUND. Apply the gold size mixture as above directed, only add a little asphaltum, or burnt sienna, or burnt umbre, to give it colour and body. Sift the flock over it. 92 No. 2. Ditto ditto : but instead of wood take a common primed cloth, such as is sold in the colour shops. PREPARED GROUNDS IN IMITATION OF THE OLD MASTERS. I shall not attempt to give any de- tailed instructions for the preparation of grounds of this description, for as they require to be managed with much care, it is better to leave them to the regular colourmen. For the priming of these grounds I recommend a composition of calcareous earths, pounded glass, marble, &c. which, if rightly managed, will leave the surface rough and porous, so as to 93 receive either oil, or water colour, or crayons. The grounds of the old masters ap- pear to be generally prepared upon this principle, pounded glass or marble being usually found mixed up with the sub- stances of which they are composed. Before you begin to paint on a pre- pared ground, sprinkle it first with the rosin binder. No. 1, and then the gin glue. No. 11, well diluted with gin. Then as you proceed with the paint- ing, fix alternate with gin and spirits of wine. \\ . • ^ / • *■ ‘ >r» 'Mi yj*v: . <•* • -! ' ' ' . '■ '. ' ■ . . ■" I....; ..... r .• -i * OF THE ALTERATION OF COLOURS BY OIL OR VARNISH. The only difficulty I anticipate on the first trial of this process is, the change produced on all dry colours by oil or varnish. It will, however, be greatly diminished by a strict adherence to the rule, which on this and on every other account, I so strongly recommend, of painting without shading colours. If painted on the ordinary plan, it would, I think, be impossible to varnish crayons 96 with any success, as the darkening of the half tints and shadows would de- stroy all gradation and breadth of co- lour; but on this system the colouring is only a little lowered in tone, without losino; its breadth. Colours, being prepared from a variety of substances, have very different pro- perties, which render them liable to this alteration in greater and less degrees; it will, therefore, be necessary for the artist to acquaint himself thoroughly with the properties of colours with refer- ence to this circumstance. The colours used in painting are chiefly native earths, or artificial pre- parations from metallic, vegetable, and animal substances. 97 OF EARTHS. Native earths are the most durable of any colours now in use. The alteration produced on them by oil, depends prin- cipally on their being absorbent, or otherwise* YELLOW EARTHS. Common Yellow Ochre . — An absor- bent earth. When oiled, changes to a sort of tan colour. Light Ochre , or Stone Ochre . — A sort of clay found in Oxfordshire, and some- times called Oxford ochre, of a bright yellow : becomes semi transparent in oil, but alters very little in colour. When / H 98 mixed with an absorbent earth makes very good crayons for outlines. Dark or Brown Ochre . — An absor- bent earth of a dark yellow colour. — Changes with oil to a warm yellow brown, and is an excellent colour for the middle tints and for sketching. Common English Ochre . — Of very similar qualities. Roman Ochre . — A fine rich yellow ; very absorbent, and darkens a good deal in oil. Raw Terra di Sienna^An ochrous earth, of a deep yellow colour and very transparent. Is, therefore, a valuable colour in oil or water colours, but its want of body and the hardness of its texture renders it unfit for crayons. 99 Naples Yellow . — Is said to be a na- tive earth found in the neighbourhood of Naples; but either this may be doubted, or it is seldom to be met with genuine, as it varies much in quality ; and, unlike the generality of native earths, cannot be depended on for durability. The best sort is, however, reckoned to stand well in oil, but if it touches iron along with the least watery moisture it will blacken. Barring these objections, it is a desire- able colour for crayons, being of a fine delicate tint, and having a good body is very little altered by oil. RED EARTHS. Ught Red , or Red Ochre .— Is the common stone ochre burnt. Alters very little in oil. When mixed with flake H 2 ; i 100 white it is an excellent colour for the flesh tints. Venetian Red . — An absorbent earth : darkens a little with oil : has a good body. Indian Red . — An ochrous earth : when genuine is a fine purple red : has a good body, and stands out well in oil. Spanish Brown . — An absorbent earth, very similar to Venetian red, but not so bright : darkens with oil, but is a very solid body colour. Burnt Terra di Sienna . — Is raw' sienna calcined, and of course resem- bles it in every thing but colour, which is of a bright orange or apricot colour. Invaluable for its warmth and trans- parency in oil or water colours, but not proper for crayons. 10! BROWN EARTHS. Raiv Umbre . — Is a very good body colour, not very absorbent : darkens when oiled. Burnt Umbre . — The same colour cal- cined : becomes darker and of a colder tint when oiled. English Umbre . — A fine warm brown of a lighter shade, in all other respects of similar qualities. Vandyke Brown . — A fine transparent brown for oil or water colours. Cologne Earth . — Very similar, but darker and more forcible. Is one of the best colours for dark grontids. 102 GREEN EARTHS. Terra Verte . — An ochrous earth brought from Italy : does not alter much with oil, and makes useful cray- ons for sketching the foliage : is very durable. Malachite Stone . ~ When pounded is a beautiful green colour, that might, I think, be found a valuable aquisition, as the artificial greens in general are not to be depended on for durability. BLUE. The lapis lazuli furnishes the finest of all blues — ultramarine ; but its high price makes it little used in modern art. Heightens a little with oil. m Ultramarine Ashes . — Useful for glaz- ing or scumbling with oil, but has not body enough for crayons. With reference to crayon painting, the earths afford excellent middle tints, and supposing the ground to be of the darkest shade, I prefer them to any other for the commencement of a picture ; but to bring out the colouring in its full strength, depends on the metallic co- lours. OF COLOURS PREPARED FROM METALLIC SUBSTANCES. The general properties of metallic co- lours are opacity and strength, and a tendency to return to their natural state. They are consequently not to be relied 104 upon for their durability, unless well defended from the atmosphere by oil or varnish. OF RED METALLLIC COLOURS. Vermilion . — A preparation of quick- silver: a very opake and powerful co- lour : does not darken in oil, but the tint is a little heightened. Dutch Vermilion . — A cheaper prepa- ration of the same kind. Stands well in oil. Native dumber . — Is a metallic com- bination formed in the earth : reckoned very durable : resembles vermilion in colour, and in every other property. Orange Lead. — A very brilliant 105 powerful colour, and very opake : is very deleterious, and liable to turn black. Does not alter in colour when oiled. OF YELLOW METALLIC COLOURS. Turpeth Mineral . — A fine bright yellow, prepared from mercury : not reckoned durable : does not darken with oil. King’s Yellow . — A preparation of arsenic : very deleterious and perishable. Yellow and Orange Orpiment . — Pre- pared from the same mineral, and the same properties in every particular. Yellow and Orange Chromes. — These 106 are newly invented colours, prepared from iron. They surpass all others in force and brilliancy, but are not reckoned durable : they retain their colour in oil. Masticot . — Is flake white, or white lead gently calcined, by which it is changed to a yellow of lighter or deeper tint, ac- cording to the degree of calcination. Crayons prepared from this colour are particularly useful in this process, as it is a strong body colour, and stands out very well in oil. OF GREEN METALLIC COLOURS. These are principally prepared from copper, and are therefore very deleteri- ous if not used cautiously. Verdigrease . — A very bright green, which heightens a little in oil. Crystals of Verdigrease — Is the salt produced by the solution of copper in vinegar. The crystals thus formed are of a fine emerald green colour. When varnished stands very well, and is very brilliant, but is not an opake body co- lour. Scheele's Green . — Is, I believe, chalk tinged with a solution of copper, and be* comes quite transparent with oil. BLUE METALLIC COLOURS. Blue Verditer . — A very bright azure blue, prepared from copper : does not 108 darken in oil, but stands out with a good body, is therefore an excellent colour for crayons. Antwerp Blue . — I am not certain whether I am correct in classing this as a metallic colour, but I suppose it to be chalk tinged with a metallic solution, from the circumstance of its changing with oil from a pale blue to the darkest shade, and becoming perfectly trans- parent. It is much used in oil painting, but I do not recommend it for crayons. OF CERUSS, OR THE WHITE OXYDE OF LEAD. Flake White.— Is the best prepara- tion, and is the only white proper for 109 this process. When mixed with any other colour it will give them body. It is in fact the only one to be depended on for strength. When perfectly pure it does not alter with oil, but it is fre- quently sophisticated with chalk, which tends to render it less white and opake when oiled. OF VEGETABLE COLOURS. These in general partake of their original nature, and are very perishable : they are the most transparent of any colours, and consequently alter consider- ably in oil. For this reason, excepting the lakes which cannot be dispensed with, I do not recommend them for crayons. 110 OP RED VEGETABLE COLOURS. Madder Lakes . — These are very beau- tiful transparent colours when ground in oil, and reckoned more durable than any other of the vegetable colours. A great variety of tints are prepared from this substance ; some appear, when dry, of a pale pink, and alter in oil to a bright ruby colour. Common Red Lake — Prepared from Brasil wood. Becomes transparent in oil. Purple Lake .- — The same in every re- spect but colour. m OF YELLOW VEGETABLE COLOURS. Dutch Pink . — Is chalk tinged with the stain of French berries, or other vegeta- ble matter: very transparent, and very perishable. Yellow Lake.— A similar preparation, and of similar properties. Gamboge . — Is a gum brought from East Indies, of a very bright transpa- rent yellow. Dissolves in water or spirits of wine. I cannot speak as to its dura- bility, but if that could be sufficiently depended on it would be a very useful yellow, when mixed with masticot to give it body. 112 BLUE. Indigo . — Is a vegetable substance brought from the East and West Indies, of a dull dark blue colour. Is reckoned to stand well, but as I am not in the habit of using crayons of so dark a shade, I do not know what difference of tint is produced by oil upon this colour. Is much used in water colours. BROWNS. Terra Japonica , or Japan Earth . — A gummy substance, extracted from some vegetable. Dissolves in water. Is of a mild brown colour, and very transparent. Is not applicable to crayons, but may occasionally be useful in water colours. 113 Brown Madder . — A fine transparent brown for oil or water colours. GREEN* Sap Green . — A vegetable colour much used in water colours, and if it could be depended on for durability might be use- ful in this process. black. Blue Black *— Is a sort of charcoal, prepared from vine stalks or other vege- table substances. When mixed with flake white is a very good colour for the composition of grey crayons. Lamp Black . — The soot of oil col- lected as it is formed by burning. i 114 OF COLOURS PREPARED FROM ANIMAL SUBSTANCES. BLUE. Prussian Blue.~A preparation from animal coal. Much used in oil and water colours. Very transparent, and darkens a good deal in oil. RED* Carmine . — A most beautiful ruby co- lour prepared from cochineal: stands exceedingly well in oil or water colour, and is a valuable crayon for crimson draperies: alters very little in oil. 115 GREEN. Prussian Green . — Differs from Prus- sian blue only in colour. YELLOW. Gall Nuts . — Of a deep yellow colour, very transparent. Is used only as a water colour. BLACK. Ivory Black .— Burnt ivory. BROWN. Sepia . — The ink of the cuttle fish : a i 2 116 fine warm brown, much used in water colours. Mummy . — Prepared from the animal remains of the Egyptian mummies. — When ground in oil is perfectly trans- parent, and is a fine glazing colour. BITUMENS. Asphaltum . — Dissolves with heat in turpentine or oil: a rich transparent brown resembling pitch, and one of the best glazing colours for oil painting. Jet . — Grinds in spirits of wine to a very fine brown of the darkest shade : dries much better than asphaltum, and, I think, might prove a useful addition to the stock of glazing colours now in use. 117 VITRIFIED COLOURS. Common Blue Smalt . — Is blue glass finely pounded : not now in use, either for oil or water colour, owing to its gritty texture, but makes excellent crayons. The colour is heightened on being touched with oil, but is otherwise absolutely unalterable. Saxon Smalt . — The same substance, but of a brighter tint, and more finely prepared. Bleu de Cobalt , or French Blue . — Is a secret preparation, but is probably a vitrified colour. Heightens a little in oil. Next to ultramarine these are the finest of all blue colours. 118 INDIAN INK. The preparation unknown. Much used in water colour, and may be used in this process in common with all other water colours. INDIAN YELLOW. Preparation unknown. A very rich and beautiful colour. OF THE PREPARATION OF THE CRAYONS. Much of the effect of the picture de- pends on the crayons delivering freely, and with a fine grain. They ought to be of different degrees of hardness. — 119 Those for sketching the outlines should approach as near as possible to the tex- ture of a red chalk pencil. The neces- sity of excluding* the calcareous whiles has already been explained. Hereafter I contemplate many im- provements in the preparation of crayons adapted to this process, among which a very important one would be the use of pounded vitrified colours. Their gritty texture, which renders them quite in- applicable, either to water or oil paint- ing, would in this process prove a great advantage, as it would assist to preserve the tooth of the surface. By this means orange lead, chrome yellows, and a vast variety of metallic oxydes might be brought into use with perfect safety, the process of vitrification rendering them 120 absolutely unalterable. At present no artist that has the least regard to the durability of his colours will venture to use them, but their great force and brilliancy would make them valuable acquisitions. Another advantage would be, that the poisonous oxydes being en- cased by vitrification, would not then give out any deleterious effluvia. It strikes me, that if the oxydes or preci- pitations of lead, tin, zinc, &c. were impregnated with glass, a very beauti- ful and durable white might be obtained suitable to this process. I throw out this hint for those who may be com- petent to try the experiment. I have tried the common white enamel, but it did not appear to have been impregnated with a metallic oxyde, and consequently had not sufficient body. 121 I am inclined to think the old mas- ters occasionlly availed themselves of the use of vitrified colours, and that the bright blue which prevails so much in the old Italian pictures, will be found to be a preparation of smalt . An emi- nent chymist has assured me, that what had been subjected to his examination was not ultra-marine. It is certain that the Italian authors mention smalt as one of the colours in ordinary use, which leaves a strong inference in proof of their mode of applying it, as on account of its gritty quality it is quite unmanage- able in oil painting. It may hereafter be a subject of en- quiry worthy the attention of men of science, whether the inalterability of the colours that yet ornament the Egyptian tombs may be ascribed to their having 122 been first subjected to a process of vitri- fication, on which may be founded some plausible conjectures as to the mode of painting then in use. IMITATIONS OF THE OLD MASTERS. From what has been already detailed, it will be obvious that this process ad- mits of an infinite variety of modifica- tions, which it would be useless, if not impossible to describe. The judgment and taste of the artist will hereafter re- gulate its application, but until a per- fect mastery is attained from practice and experience, the surest course is for him to fix on some particular master as his guide and model, whose style of art 124 tnay best correspond with his own. For rural nature, and day light tones, the Flemish school offers the best models for imitation. OF THE FLEMISH SCHOOL. It appears to me that the Flemish masters almost invariably began their pictures with red chalk, upon a bright orange or amber coloured ground, a process that will be found to give re- markable brilliancy. Red chalk glazes to a very fine tint for the under tones ; when broken with yellow, it is the best combination that can be adopted for the under colour of luminous day light shadows. 125 IMITATIONS OF CUYP, PAUL, POTTER, &C, Directions . — The ground may be either white calico, or a white prepared ground. On this sketch the whole design, and shade in the masses with a red chalk pencil. It may be softened in with a leather stamp or not, as you choose. As you proceed fix the colours alternately with varnish binders and water binders, so as to keep the tints separate . Strengthen the shadows in water colour with burnt sienna : the burnt sienna is only a deeper shade of the same tint. Then go over the whole with a bright gold or amber colour so as to represent a glowing sun- shine *. After securing the under colour * It is quite immaterial whether the ground is coloured in this stage, or when the picture is first begun. 126 with a varnish binder, wash in the shadows to their full strength, with umbres, Vandyke brown, Cologne earth, &c. and tinge the trees and draperies with their local tints. The golden tones of the under colour will break finely through the foliage, and the whole pic- ture when finished and varnished will be beautifully illuminated by the ground, or what is technically called the luce di sotto. The design thus prepared, you may then crayon in the lights and local co- lours. Touch the trees lightly with greens and yellows, and take care to embody the light of the sky and the draperies with as much force as you can. When you have done all that can be done with the crayons, saturate the picture with the oil mixture. No. 6, 127 and then finish with oil colour, pencil- ling the lights of the foreground, foliage, &c. freely, and scumbling the sky and distances, wherever the harmony of the picture requires it. When thoroughly hard, glaze with any tint you like. If we consider shade, substance, and air, as the elements of painting, we shall find that in a picture executed on this plan, each has its proper repre- sentative. Thin impalpable water co- lour for shade : substance, embodied with oil colour or crayons, according to its texture : air, by the interposition of a diaphanous medium on the distances, in the operation of scumbling. On these principles the Flemish masters attained the truest imitation of the day light tones of nature. 128 Claude may be imitated exactly on the same plan. WOUVERMANS. The same, only that the ground should be finely prepared, and of a sort of tan colour. TENIERS. In the Flemish masters the main dis- tinctions that are observable in their manner, seem to arise from the degree of roughness or smoothness of their grounds. Teniers painted on finely pre- pared grounds, sufficiently porous to im- bibe the water colour, but not rough 129 enough to receive a body of dry colour. His pictures have the appearance of being done principally in water colour and red chalk, and then freely pencilled with oil colour. When the ground is well prepared, the chalk casts with great sharpness and delicacy of finish, and the whole may be very finely made out be- fore a touch of oil colour is introduced. In the management of his half tints, Teniers had a peculiar manner of sub- duing the fiery tints of the ground, by thin tones composed of the umbres, ochres, and other mild colours, which gave an extraordinary delicacy to his execution. REMBRANDT. Rembrandt may be imitated on the general principles of the Flemish school. K 130 that is, with red chalk, and water colour upon water colour , till the tones have reached their full strength. His shadows are remarkably luminous, and so trans- parent, that in many of his pictures his under-sketching is quite distinguishable : sometimes, however, he evidently began on grounds of the darkest shade. The powerful manner in which he embodied his lights, indicates that his grounds must have been prepared with an unusually rough surface. OF THE ITALIAN SCHOOL. The Italian masters painted with greater depth than the Flemish, and (with the exception of Rembrandt,) with a greater body of colour. The texture of the ground is, therefore, a 131 main consideration in imitations of the Italian school. IMITATION OF TITIAN ON A DARK FLOCK GROUND. As I think the Venetian painters made crayons the principal in their system, I prefer a flock ground for an imitation of a Venetian master, because it will take up the crayons with a richer body than any other ground. It is, however, quite at the discretion of the artist to select whatever ground he pleases. DIRECTIONS. 1st. Trace the outline with a red chalk pencil, or with crayons of some k 2 132 middle tint, as red, yellow, and brown ochre. 2d. Sketch in the lights and local colours. 3d. Fix with spirits of wine : the fixing will degrade the co- lours one or two tones. 4th. Repaint and embody the lights till the ground is quite saturated with colour. Continue to fix as occasion requires, alternate with varnish binders and water binders. Paint the flesh with its simple local tint, leaving the blues and greens, and all cold colours to be scumbled in with oil colour in the last finishing : this gives great breadth and truth to the tones. Do not rub in the crayons with your finger, as is usually done, but touch with a fine light hand, so as to preserve that porous granulated texture peculiar to the Vene- tian school. Be also careful to preserve the roundings of the forms, by always 133 touching from the focus of light. When the ground will receive no more colour, let your last fixing be with a water binder, and then the oil binder, No. 6, may with safety be applied either to the surface or the back of the picture. Till the oil is quite dry the colouring will ap- pear considerably lowered in tone ; you have then to brighten the lights with oil colour. The principles by which the Vene- tian painters regulated the application of oil colour now remain to be con- sidered. I have already noted, that they appear to have excluded it as much as possible from the masses of all soft substances, such as flesh, drapery, sky, &c. reserving it for hard shining bodies, or sharp angular figures, as in architec- 134 tural ornaments, the leaves of trees, buildings, &c. In touching the flesh with oil colour, they appear to have applied it chiefly to the bony or carti- laginous parts, or the glossy lights about the eyes, &c. A few touches on white linen gives great relief to the colouring. BASSAN. Bassan may be imitated nearly on the same plan, but his grounds are generally darker than Titian’s, and his lights more impasted with oil colour. PAULO VERONESE. Paulo Veronese usually painted on light coloured grounds, in consequence of which his tones have not the depth and richness of Titian. CORREGGIO. Correggio is said to have paid extra- ordinary attention to the preparation of his grounds, and to some particular advan- tages of this Mud lam inclined to attribute some of his most striking excellences. He appears to have frequently painted on a gold ground, coloured over with a deep shade of asphaltum or some rich trans- parent brown, and probably prepared with so fine a grain as to enable him nearly to complete his picture in cray- ons; hence the peculiar tenderness, or in the technical language, morbidezza of his colouring, and the fine roundings of his figures. His surface is less granu- 136 lated Ihan the Venetian masters, owing perhaps to his having occasionally blend- ed the crayons by rubbing them in with his finger ; a practice which materially alters the appearance of the surface. IMITATION OF THE EARLY MASTERS. Gilt grounds, prepared in a similar manner, were very commonly used by the early masters of the 14th and 15th centuries: they give a surprising lustre to the transparent colours, and I think might occasionally be adopted with great advantage. I have often detected the use of gold in the later Italian masters, and have occasionally used it myself with great advantage on dark grounds, by first painting in the lights with liquid gold, then finishing with crayons and oil colour. THE SCHOOL OF CARRACCI, ITS RISE AND GRADUAL DECLENSION. The school of Carracci established a new era in painting, which may also be regarded as the last. At the close of the sixteenth century we are told *, that a new style was introduced by these masters, compounded of the Roman and Venetian manner. Ludovico Carracci was the inventor of this style. Having conceived in his mind the idea of a more perfect style of art than any he had yet seen, he visited the different cities of * See Lanzi, Pilkington, &c. 138 Italy in order to study all the great works of art, more particularly the works of Raffaelle Correggio and the Venetian school. Collecting from each what was most excellent in their system he formed a style of his own, which attracted uni- versal admiration, and finally superseded that of every other master in Italy. On returning to Bologna, his native city, he lost no time in preparing to put a favorite and long meditated scheme into execu- tion ; the formation of an academy of painting on these new principles* In this he was joined by his two cousins, Hannibal and Agostino Carracci, and a long list of distinguished scholars, among whom were Guido and Domenichino, give abundant proof of its success. The style of Ludovico Carracci, Sir Joshua Reynolds describes as in his 139 mind approaching the nearest to per- fection. “ His unaffected breadth of light and shadow, the simplicity of co- louring, and the solemn effect of that twilight which seems diffused over his pictures, corresponds with grave and dignified subjects, rather than the more artificial brilliancy of sunshine which enlightens the pictures of Titian.” Thus recommended, it is to this school the historical painter will direct his at- tention, as affording the best models of imitation. The mechanical means by which this imitation can be accom- plished is our present consideration. HANNIBAL CARRACCI. The depth of lone and solidity of 140 effect, which distinguishes the Bologn- ese from the Venetian masters, I think arose principally from these two circum- stances. Their beginning their pic- tures on grounds of a deeper tone, and strengthening and embodying their lights more freely with oil colour than the taste of the Venetian masters admitted. The difference of process would therefore be very inconsiderable ; but the difference of surface and the general effect is very decided and striking. With respect to dry colour, the Car- racci seem to have regarded it rather as the mechanism of design than of colour ; as the best means of attaining harmony of light and shade ; and in short, as a general preparation of their whole design for a last finishing of oil colour. 141 An imitation of Hannibal Carracci is, I think, fully attainable on these princi- ples. The ground should be of a good texture, and of a very dark shade. While controuled by the judicious taste of the Carracci, the oil system was never carried beyond its just limits, so as to degenerate into coldness and opa- city ; but these limits seem gradually to have been lost sight of, and from that time the art rapidly declined. DOMENICHINO. For depth and richness of tone Dome- nichino is unrivalled. His surface has less oil colour than Hannibal Carracci, 142 and his grounds seem harder and better prepared. GUIDO. Guido’s taste led him to adopt a silvery tint in preference to the more mellow tones of Carracci and Domenichino, and this would probably oblige him to vary the tint of his ground accordingly. f i \ i ; I ' * GUERCINO. The scholar of Guido, who in imitating his manner degenerated into coldness. Is occasionally spotty and opake, so as to lead to a supposition that he had not strictly adhered to the course of prepara- tion derived from the Venetian school. 143 ALBANO. Another of Guido’s scholars, who seems to have varied the Bolognese man- ner ad libitum , as his pictures have not always the same force of colour, pro- bably owing to some difference in his grounds. CARLO CIGNIANI. Carlo Cigniani painted with great strength, and was upon the whole a suc- cessful imitator of the Carracci ; but he appears to have carried the oil system a little too far, as his colouring is occa- sionally cold and opake. He had se- veral scholars who adopted his manner, and in a greater or less degree fell into similar defects. 144 THE ROMAN SCHOOL. The Bolognese manner had been adopted into the Roman school, in com- mon with all the other schools of Italy, and produced many eminent examples of its excellence, which it is needless to par- ticularize. CARLO MARRATTI. The works of this master evidently shew an entire departure from the sys- tem of his predecessors, as respects the clair obscure. There is a mealiness* and * The change produced on certain transparent colours by the mixture of flake white or other body colours, will explain the cause of that appearance technically termed mealiness. The rich transparent browns used in the shadows, if mixed with the 145 flatness in Ins colouring, which indicates that his lights and shades were painted and blended together in oil colour, a practice that appears to have been first introduced at Rome by Vouet, a French painter, in the seventeenth century, and to which his countrymen still most religi- ously adhere. At the latter end of the seventeenth century Carlo Marratti was placed at the head of the Roman school, and under his auspices the art rapidly de- generated into mere oil painting. smallest portion of flake white, will immediately alter to a cold muddy tint, that gives a remarkable coldness and flatness to the colouring. Those who are well acquainted with the pictures of Le Soeur, and others of the French school, will easily com- prehend the effect I would describe. L MISCELLANEOUS OBSERVATIONS. By this gradual dereliction of the prin- ciples that had heretofore regulated the practice of the Italian schools, all traces of their system at last sunk into total oblivion. Italy had long been the cen- tral school, from which Europe received her instructions, and when the teacher fell into blindness, darkness spread far and wide. The brilliant tones and sun- shine of the Flemish school rapidly dis- appeared. The German, French, and Spanish schools, though they had less to lose, have the signs of similar declen- sion. England is exempt from the re- proach of losing what she never pos- l 2 148 sessed, excepting as it was practised by foreigners. Holbein and Vandyke, though they resided for a length of time in this country, do not appear to have left any inheritors of their process, what- ever it might be. That it differed from the oil painting of the present day, no one can doubt whose eye is accustomed to the mellow tones of the old masters. But let this be admitted, and it may still appear strange that no vestige of this lost art should be found to exist. If, however, they painted on a system such as I have attempted to explain, (which is my firm belief,) I am satis- fied it might easily be lost sight of from the moment that they ceased to pay the requisite attention to the preparation of their grounds, and this in all probability would occur when once the habit of painting simply in oil colour became 149 prevalent. It must also be recollected, that in these times every artist was his own colourman *. Every one had his own secret preparations, which we may naturally suppose would be guarded with some degree of jealousy, a cir- cumstance that is indeed frequently ad- verted to in the lives of the painters -f*. # The first colour shop for artists is said to have been established in London by a servant of Sir Godfrey Kneller’s, who had been in the habit of preparing- his master’s colours ; and from that time the business of a colourman has continued to be a regular trade. f An anecdote is related of Bassan that offers a remarkable instance of this jealousy. He was the disciple of Bonifazio at Venice, a master who, ac- cording to Ridolfi, was not less tenacious of his “ mystery” than Titian or Tintoret, and carefully withheld it from his pupils. It is recorded, that Bassan discovered the secret of his art hy looking through the key hole of his masters painting room while he was painting. (Vide Pilkington’s Diction- ary.) What he saiv we are not informed, but a strong inference presents itself, that what he so readily dis- 150 If ever this process comes into general use, the importance of the ground, and the great care and attention that is ne- cessary in preparing it on the principle of those used by the Old Masters, will then be thoroughly understood. All that I have had an opportunity of in- specting, appear to have been invari- ably prepared with some calcareous composition, and as far as my informa- tion goes on the subject, fritz of some sort or another is always found mixed with it, for the purpose, no doubt, of rendering the surface rough and porous . This careful preparation would naturally fall into neglect, from the time that the later masters allowed themselves to paint with an entire surface of oil colour, and covered as an object of sight was a difference in the implements of art ; in other w ords, that he saw him apply the colour with crayons instead of a brush. 151 I believe it will be found that the prac- tice of priming canvass with oil paint has for the last hundred years or more almost universally prevailed. On a ground of this kind the picture is ne- cessarily begun, and finished with a body of oil colour without discrimina- tion of substance. Whether flesh, or drapery, or stone , all are equally hard, opake, and cold, so far at least as these qualities may be regarded as the con- tradistinctions of oil painting. The sky and distances, when painted with an opake body of colour, will un- avoidably come too forward. Hence arises a necessity for that overcharged manner in which the figures of the fore- ground are occasionally embodied by modern painters, as the only means of making the more distant parts retire into 152 true keeping. In large compositions this can scarcely be avoided, but the effect is far from satisfactory, shade being em- bodied with light, the track of the brush perplexes the eye in all directions. It was not so with the Old Masters ; Rem- brandt and many others were in the habit of impasting their pictures with great force, but it was the lights only , and thus they preserved the true rela- tions of light and shade. Of late years some improvements have been attempted by introducing the use of dark absorbent grounds, but which do not appear to offer any adequate remedy for the defects of the modern system. The very first touch of oil colour chokes up and saturates the absorbent surface, and a second painting amounts to nothing more than oil colour upon oil colour , 153 Here lies one of the advantages of a system of dry colouring; not only the absorbent quality of the ground will be preserved, but the whole body of colour will be as absorbent as the ground itself till the last finishing ; and the effect will be what I have already described, as if the picture had been done at once. Among other advantages may be added one of inestimable value to the historic painter, namely, the preservation of his first thought, and conception of charac- ter in the original sketch. If it should be doubted how far the great style is dependent on the excellence of process, I would urge this in proof; — the fine freedom of outline it secures, and with it that greatness of manner that arises from well designed contours. 154 Regarding colouring as a separate end, and as such one of the lowest at- tainments of the art, has led to many erroneous opinions on the subject. Some even profess a sort of contemptuous dis- regard of all that comes under the de- scription of the mechanical part of the art, as unworthy their attention. Its real value and importance however is relative ; and as the means by which the higher objects of art are attained, it can never be a matter of indifference to the man of true genius, who is not the mere copyist of individual nature, but the transmitter of ideas pre-existing in his mind. If here he has mechanical dif- ficulties to contend with ; a slow unim- passioned process to pursue ; the imagi- nation chills in the interval, the first powerful impression is lost, and he pro- 155 ceeds on the faint traces that are left on his memory. The most powerful genius will be enfeebled by a process of this nature. The art of painting should be re- garded comprehensively. The mechanic and ideal as inseparably allied. A true imitation of nature in all her variety is its genuine object, whether in the sim- plicity of rural life, or aggrandised by the beautiful and sublime, good taste and feeling will ever recognize with de- light her genuine features. That the glow and harmony of colours is inti- mately allied with our ideas of beauty, few can hesitate to confess, after con- templating the superb colouring of a fine sun set. There are few objects that would not be rendered more beau- 156 tiful or picturesque, when tinged with the lustre of its rays. But with reference to art, it is not the mere brilliancy of local tints that charms us in a well coloured picture, but the fine harmony that pervades the whole, and which is in fact essential to the pleasure we derive from all arti- ficial combinations. Harmony, as far as mechanism is con- cerned, appears to me to arise princi- pally from a right management of the light and shade; and with respect to colouring, less on the choice and ar- rangement of the colours, than on their transparency and porosity of texture. Opposed to this is opacity of surface. 157 which shocks the eye as a discord does the ear ; and so repugnant is it to the sense, that I do not conceive it possible for a picture to please, let the ideas be ever so noble, if the eye is shocked and disturbed by crudeness and opacity. ■ ON THE MORAL CAUSES THAT INFLUENCED THE ARTS IN THE SIXTEENTH CENTURY. But though I conceive certain me- chanical facilities to be essential to a free expression of the ideas, and that the Old Masters did possess some advan- tages of this nature over the moderns, to which I have been led to ascribe, in a great degree, their comparative excel- lence, I would not be understood to have overlooked the operation of moral causes on the genius of the age. The progress of society is marked by particular pe- riods, more or less favourable to a suc- cessful cultivation of the arts : this was most propitious. 160 The revival of letters in the fourteenth century had given a powerful impulse to the different nations of Europe, and was accompanied by circumstances singularly calculated to produce that high order of genius which adorned the period that succeeded. The ordinary approaches to knowledge are slow and laborious, but the stream of intelligence rushed upon the mind with a suddenness that at once roused into action its long slum- bering faculties. The age was as it were new born. The freshness of na- ture yet bloomed upon the earth. The mind of man was yet unsated by know- ledge, it possessed the health and vigour of youth, its lively perceptions and ac- tive powers; its native energies were not broken down into dull uniformity by servile imitation. Curiosity and in- vention coursed in untrodden paths, and 161 ranged at large, unfettered by rule, over the wide field of science and art. With this freshness of the imagina- tion and feelings, was the art of painting first revived by Cimabue, a native of Florence, at the close of the thirteenth century. The liveliness of new impressions are strikingly exemplified by the enthu- siasm with which the Florentines hailed the first dawnings of art in their country- man. A picture of the Virgin, which he had painted for the church dedicated to her at Florence, excited such enthu- siastic delight in his fellow-citizens, that they treated the painter with almost di- vine honours. The picture was carried in procession, accompanied by triumphal music, from the house of the painter to the church. The day was celebrated as a public festival, and the street through M 162 which the picture passed was named, as it is to this day, II Borgo Allegri *. Cimabue had several scholars, among whom the most celebrated was Giotto. He was a shepherd’s boy, and while tending his flocks was observed by Cima- bue sketching the figures of his sheep on a stone. Struck with what he saw he immediately invited him to become his pupil; and Giotto now fully shares the fame of his master, as one of the early revivers of art. The rudest imitations of nature are, however, all that can be looked for from the art in its first infancy, nor does it appear to have advanced much beyond these limits until the latter end of the fifteenth century, when the restoration of * Vide Anecdotes of Painters. 163 the remains of ancient sculpture so long lost to the world gave to the painter that standard of beauty and grandeur which led him on to its higher attain- ments. For several succeeding ages the trea- sures of ancient Rome had laid buried under the ruins of its former grandeur. It is said, that of the innumerable works of art, which till the times of the later em- perors had decorated the palaces and vil- las of the Roman nobility, scarcely a spe- cimen or a vestige was in the beginning of the fifteenth century to be found. But the curiosity and interest that had been excited by the discovery of ancient manu- scripts, was soon after extended to every relic of antiquity in marble, gems, and other durable materials that had survived the desolation of the middle ages, and m 2 164 was followed by similar results ; for white the writings of the ancient authors re- fined the taste, and exalted the imagina- tion of the poet and the scholar, the re- mains of ancient sculpture in like man- ner awakened the genius of the artist, and were regarded not only with delight and admiration, but as instructors and models*. To facilitate the progress of * Among the discoveries of this period were the Laocoon, the Apollo, the Torso, and, I believe, the Venus de Medicis. The groupe of the Laocoon was discovered in the pontificate of Julius II. in the ruins of the baths of Titus, where most probably it stood in the time of Pliny, who has described it to be there in the reign of that emperor. The encouragement afforded to those who devoted themselves to these researches gave new vigour to their exertions. The discovery of a genuine specimen of antiquity secured to the fortunate possessor a competency for life, and the acquisition of a fine statue was almost equivalent to a bishoprick. See Duppa’s Life of Michael Angelo. The Apollo of Belvidere was found about the end of the 15th century on the sea shore, twelve leagues from Rome, among the ruins of Antium, m these studies, collections were formed in all the principal cities of Italy, and thrown open to the artists. It was then that painting rose to its higher objects — character and expression, and began to address the passions and to interest the feelings of mankind *. The sixteenth century now opened with a splendour, that fills the mind with astonishment. The arts rising from the ashes of ancient Rome, and nursed in the genial climate of Italy, advanced at once to full maturity and vigour. Protected and ennobled by the Julius II. then only cardinal, purchased it, and im- mediately placed it in the palace he then inhabited ; afterwards on his being made Pope, it was removed to the Vatican. The Torso also was found in the pontificate of Julius, and placed by him in the Va- tican. # See Roscoe’s Life of Lorenzo de Medici. 166 magnificence of its pontiffs, and inti- mately associated with the mysteries of a religion, whose empire over the imagi- nation is maintained by the grandeur and sublimity of external objects, the works of this period are characterised by a greatness of manner, for which perhaps we may vainly look under cir- cumstances less auspicious. Among the benefactors of the arts, none have a better claim to the grati- tude of posterity than Pope Julius II. and his successor, Leo X. ; but for them the stupendous powers of Raffaelle and Michael Angelo had, perhaps, never been fully developed. The character ot Julius in a remarkable manner assimilated with the genius of Michael Angelo,— grand, daring, and impetuous ; they appear to 167 have had a sort of instinctive attraction to each other, from which sprung the gigantic conceptions of the Sistine chapel. The treasures that flowed into the coffers of Pope Leo, from the sale of indulgencies, were freely expended in adorning with the choicest works of art the sanctuaries and palaces of the Holy See. Under his pontificate the church of Rome shone with a blaze of magnifi- cence that blinded by its splendour. And here we may be allowed to re- gret, as one of the consequences of these abuses, that severity of opinion in the early reformers, which in their hos- tility to the errors of the church of Rome, led them to reject the natural alliance of the grand and beautiful with devotional feeling. There is an appear- 168 ance of frugality, not to say parsimony, in some of our Protestant churches, that ill accords with those solemn impressions ; that religious awe which ought ever to in- fluence the heart in the performance of a religious rite *. * The magnificence of the Catholic worship, and the feelings it excites, are beautifully described by Madame de Stael, in Corinne. “ Ces tableaux ou les saints a genoux expriment dans leurs regards une priere continuelle ; ces statues placees sur les tombeaux comme pour se reveiller un jour avec les morts, ces Eglises et leurs voutes immenses ont un rapport intime avec les idees religieuses,* J’aime cet hommage eclatant rendu par les hommes k ce qui ne leur promet ni la fortune, ni la puissence ; a ce qui ne les punit ou ne les recompence, que par un sentiment du coeur. “ J’aime cette prodigalite des richesses, terrestres pour une autre vie, du temps pour l’eternite ! Assez de choses se font pour de- main; assez de soins se prennent pour 1’economie des affaires humaines. O ! que J’aime l’inutile ! 1’inutile si l’existence n’est quun travail penible pour un miserable gain. Mais si nous sommes sur cette terre en marche vers le ceil qu y a’-t-il de mieux 169 The spirit of Catholicism has always closely allied itself with those sympa- thies from which originate the faculty of taste ; and co-operating with the tem- perament of Italian character, as it is influenced by climate, raised the standard of taste to its highest elevation. This, in fact, appears to be the real influence of climate on the arts ; not as it creates the powers of genius, but as it gives the stirring impulse in the constitutional susceptibilities it bestows. The pleasures derived from the arts of music, painting, and sculpture, are among what may be called the necessary luxuries of an Italian ; and the enthusiasm with which a faire que delever assez notre ame pour quelle semble l’infini l’invisible et l’eternel au milieu de toutes, les bornes qui l’entourent!’ — Corinne, p. 169, vol. ii. 170 these arts are cherished, is the highest incentive to genius. The standard of taste will ever act on the mind of the artist, and exalt or subdue it to the tone of general feeling. The great style in painting demands the animating con- sciousness of kindred perceptions. Not only this, but a certain dignity of character almost invariably blends itself with the higher faculties of the mind. Could it be endured that the proud in- dependence of Michael Angelo should bend to the humiliations of patronage ! He lived in better times, and the loftiness of his genius had its proper aliment. The high courtesies of chivalry yet survived the decay of its early institu- tions, and its generous loyalties included m in its worship all that was pre-eminent in human attainments. The different governments of Europe were ruled by princes, deeply imbued with a love of the arts, who in the heroic spirit of the age vied with a generous rivalry in the dis- tinctions they lavished on the great mas- ters of this favoured period. Unlike the depressing patronage of modern times, it was the sympathetic offering of noble minds to a grandeur of spirit congenial with their own. “ But the age of chivalry is gone !” From the splendid and heroic, we must turn to the sober rationalities of English character, and the subduing influence of modern society. Can the revival of art be looked for, even were its mechanism fully regained, is a question I meet with a mixture of hope and apprehension. 172 The former however prevails ; and to excite it in others I will here extract some passages from Richardson’s cele- lebrated Essay on Painting, which under my present impressions seem to have the authority of prophecy. “ I have said it heretofore, and will venture to repeat it : if ever the great style in painting, if ever that delightful, useful, and noble art does revive in the world, it is probable it will be in Eng- land. “ Thus a thing as yet unheard of may come to be eminent in the world, I mean the English school of painting ; and whenever this happens who knows to what heights it may rise, for the English nation is not accustomed to do things by halves. 173 “ In ancient times we have been fre- quently subdued by foreigners. The Romans, Saxons, Danes, and Normans have all done it in their turns. Those days are at an end, and we are by vari- ous steps arrived at the height of mili- tary glory by sea and land ; nor are we less eminent for learning, philosophy, mathematics, poetry, strong and clear reasoning, and a greatness and delicacy of taste. “ Let us put forth our strength and employ our national virtue, that haughty impatience of inferiority which seems to be the characteristic of our nation, on this as on many other illustrious occa- sions, and the thing will be done. — The English School will rise and flourish !” 174 It is now fourteen years since tiie drop of wax fell on the crayon draw- ing . If this little incident shall have laid the foundation for the accomplish- ment of this prediction, it may hereafter be recorded in the chapter of accidents as one of the most memorable in our national history.
