The following pages have been written with immediate reference to the wants of the amateur and the professional student. To the former, it is hoped, it will give a complete insight into the nature of Perspective, and its application to objects generally, as well as afford him additional facilities in sketching from nature, and of delineating from memory any simple form ; to the latter, it will supply such a summary of the leading principles of the science, and their application, as shall prepare him at a future period of his studies for the better comprehension of the nature and laws of vision, and theory of intersecting planes, con- stituting the basis of perspective, and those details of practice essentially necessary to the completion of the studies of the pamter. Our first efforts at imitation are naturally directed to such objects as are immediately around us ; but it not unfrequently happens that the diminutive size of these in-door objects, as compared with buildings in a landscape, causes their forms or boundary lines to vary with every movement of the aye whilst sketching them, and is con- sequently productive of great perplexity to the student. Hence the necessity of a treatise, pointing out the appli- cation of rules to such objects, as also to enable him, in B 6 INTRODUCTION. the numerous cases where definite rules will not apply, to test the general truth of his outline by a knowledge of the laws governing the appearances of all bodies. It unfortunately happens that in most elementary treatises on perspective, designed for the youthful student, as well as the adult, it has been a custom with writers to introduce the subject either with a description of the perspective plane and theory of vanishing lines, the nature of which cannot at the outset be comprehended, or to encumber his subject with a multiplicity of geometrical terms and figures, of only a few of which he has any positive need in practice ; — unmindful that the ardent temperament of the votary of the Fine Arts is least of all fitted for calm reflection or patient investigation. In the outline of the science which follows, the per- spective plane is altogether omitted, as well as all theore- tical matter not absolutely essential for the comprehension of the rudiments of the science, from the writer's conviction that in the endeavour to elucidate a few simple truths by a too premature recourse to imaginary planes and systems of rays, the student wearies of the theme, and at length turns from it in distaste. On the system adopted in this treatise, mathematical accuracy in the application of the rules is not aimed at, for the simple reason that no advantage could possibly result from its observance ; for the painter, whilst sketching, can no more keep his eye rigidly confined to one spot, than he can the eye of the spectator who views his performance. Hence the futility of the artist in seeking to discover the angle of inclination of a building, the dis- tance of what is termed the picture, and the precise situa- tion of remote vanishing points. His compasses should INTRODUCTION. 7 be in his eye, and if the inteUigent spectator recognizes the truth of his representation, the end is accomplished. With the architect the case is far otherwise ; his combina- tions exist only in his plans and elevations ; every consi- deration becomes to him of paramount importance ; he has no alternative but to avail himself of all the resources of this elegant art, to give to the creations of his fancy all the truth and reality of a drawing from the actual object. The plane of the picture, and the theory of vanishing lines, will be found fully described in the Illustrations of Perspective,"* by the author of these pages, a work expressly adapted for the painter, and in which every subject needful for the student (not contained in this Guide") will be found fully treated of Technicalities, as far as practicable, have been studiously avoided ; and such objects selected for illustration as are to be met with in every dwelling, so that reference can be had to nature on the spot ; and the student cannot be too early and too frequently urged to examine, compare, and judge for himself. * Published by Messrs. Rowney and Co. 8 Chapter I. APPEARANCES of OBJECTS. On viewing any object except a sphere, we find its appearance not only differing from the actual form, but varying with every change of position. Thus we have a variety of objects represented in the following plates, in which Ave observe lines in them seemingly tending upwards, downwards, or sideways, which we know in reality to be perfectly level, others apparently converging towards cer- tain points, though parallel ; again, surfaces equi-distant in nature, approaching each other and diminishing as their distance from us encreases, and circular forms appearing as ellipses or merging into right lines ; but so familiar are their appearances as there represented, that we recognize in each one the object intended. Now the chief end of drawing is to give such a representation of an object that it may convey to the eye as nearly as possible the same appearance as that of the object itself. Accustomed, how- ever, as we are from childhood to the exercise of our sense of sight, so intuitive may be said to be its results, that we are rarely led to enquire into the differences subsisting between the forms and appearances of objects, or to acquaint ourselves with the causes of such changes. Thi^ DEFINITIONS. 9 investigation, nevertheless, constitutes the basis of all cor- rect drawing, since we are thereby enabled to deduce the rules for our guidance in the pictorial representation of objects. We shall, therefore, after a brief summary of the principal definitions, proceed to consider the circumstances under which objects are seen. Chapter II. DEFINITIONS. Frequent misconceptions having arisen in treatises on perspective, from the incompleteness of a few definitions relative to lines and angles, from the conventional terms and figures applied to them, we shall briefly enumerate, in this place the most essential points to be observed in connection with them. The positions of lines abstractedly considered are three : viz.. Horizontal, Vertical, and Oblique, as shewn in plate 1. But their positions to each other, also three in number, are distinguished by the terms. Parallel, Perpendicular, * and Inclined, — terms, it will be seen, different in their 10 PARALLEL LINES. signification from the former three, though too often con- founded with them. Parallel lines are such as are equi-distant from each other in every part, whether they be horizontal, vertical, or oblique. Lines are said to be perpendicular to each other when they meet or intersect so that the angles on either side are equal to each other, and these angles being right angles, the lines are also said to be at right angles to each other : it will be seen by the illustration that the perpendicularity of the lines is mutual, and that an oblique line may be perpendicular to another oblique line. Lines INCLINED to each other are those which meet or intersect at an angle greater or less than a right angle. In illus- tration of the above terms, the front edges of the flight of steps in the same plate would, in nature, be parallel to each other, but at right angles to the upright edges, in the same manner that the treads of each step are parallel to each other, but perpendicular or at right angles to the sides and fronts. The walls of an apartment are at right angles to the floor. In the pyramidal roof, all the lines or edges as well as the surfaces are oblique to each other. Mention being frequently made in perspective works of the position of lines and surfaces to the eye or to the spectator, to which the above terms of Parallel, Perpendicular, and Inclined, could not strictly apply (especially in reference to the former, — seeing that the eye is considered as a point,) a classification analogous to the above may be adopted in its stead. Thus, a line or surface may be said to be square to the spectator, in lieu of parallel when seen of its full size, and so situated as to preserve its true shape and * DEFINITIONS. [Plate 1. ERRATA.

Again, a line or surface is said to go direct from the spectator, or be at right angles to us, when not inclined to the horizon, or to either side Of this descrip- tion, consequently, are all level surfaces, as the Chess- board and Jig, 2 in plate 2 ; also the fronts of the buildings in the " Street View" and the walls of the Interior," which only apparently incline towards each other, they being in nature parallel. If we stand with our back against one side of a room of the ordinary form, the side opposite would be square to us, the floor, ceiling and two remaining sides going off direct. The walls of the Observatory" exhibit the most familiar example of surfaces oblique to the spectator; next to these may be instanced roofs, which are also inclined to the horizon. Horizontal Line. The Horizontal Line is a level line crossing the drawing from side to side, the exact height of the eye, and corresponding with our horizon or line of distance, and in a marine view with the junction of sky and ocean. The height of it on the drawing will depend upon the nature of the view to be represented. Prime Vertical Line. The Prime Vertical Line, occasionally used, is a line at right angles to the horizontal line, crossing it imme- diately in front of the eye. 12 VANISHING POINT. Seat of the Eye. The Seat of the Eye is a point formed upon the draw- ing hy the intersection of the above lines, and is commonly bnt erroneously called the " Point of Sight.'' In theory this Point" is designated the Centre of the Picture, whilst the Point of Sight" is the term applied to the eye of the sketcher ; it is a point, therefore, at some distance out of the drawing. Vanishing Point. A vanishing point is a point on a drawing towards which any line tends^ or into which two or more lines converge. APPEARANCES OF OBJECTS. [Plate 2. 13 Chapter III. RELATIVE SITUATION of the SPECTATOR and THE OBJECT TO BE DRAWN FROM. 1. — Height etc. of the Eye with relation to the Object — Vanishing Lines. By the above title is understood whether the object viewed is above, below, in front, or on either side of us, all of these conditions may be comprised ; as in the case of an Interior {plate 3) ; but they will apply generally to buildings in a landscape, furniture and miscellaneous arti- cles. Let us then suppose ourselves stationed upon level ground, or at a moderate elevation, and the object before us to be one of considerable height, as the view of the Royal Observatory, {plate 2), and we find the upper lines of the building tending downwards towards the horizon ; if, on the other hand, the subject be one lying below the eye, as the lines of a railway, we shall find the lines, equally the repre- sentative of horizontal lines with the fomier, tending up- wards in the drawing towards a point on the horizontal line or level of the eye, called their vanishing point. It will be seen that these lines, unlike the above, tend to the same point on the horizontal line ; for the reason that lines parallel to each other have a common point of convergence B 2 14 HEIGHT OF THE EYE ETC. or vanishing point. This important j^rinciple is most striking on viewing the Chess-board, {plate 2) which has a number of lines running parallel to each other; and as this article is usually seen upon a table, the lines going off from the spectator will, apparently, incline upwards, and meet in the same point, on the horizontal line. Again, on looking down a long straight street, (see figure 3), we see the upper lines of the houses apparently descending, and their bottom lines ascending, according to their situation above or below the eye ; the lines here being at the sides of the drawing. In all the above cases we have limited ourselves to the consideration of horizonlal lines in buildings going off direct (or at right angles) and oblique to the spectator, being those which chiefly concern the painter ; but retiring lines in objects, however situate in respect of us, have the pro- perty of invariably seeming to tend in the direction towards ivhich the eye is bent. The view of Edinburgh from the Calton Hill furnishes a striking illustration of this truth, differing from the pre- ceding from the fact of our looking on the city from an eminence, thereby causing the horizontal line to be situate high up in the drawing : this line being invariably found on a level with the eye, when we ascend it appears to rise with us. As the upper lines of the Observatory seemed to descend, from the circumstance of our being on level ground, so in the present case the corresponding lines of the buildings appear to ascend. It will be observed that in the Street View the obliquity of the lines is governed by their proximity to the horizontal line, the inclination becoming less and less as they ap- i PLACE OF THE EYE. [Plate VERTICAL LINES. 15 proacli it : this brings us to the consideration of Vanishing Lines. Vanishing Lines are the lines on which the vanishing points alluded to are situate, hence the necessity for them on the drawing ; but they are also highly important to the student, as governing the appearances of surfaces. Having spoken only of lines in buildings, our attention has now to be directed to the surfaces on which these lines appear, which, as will doubtless have been surmised, are subjected to similar changes in their appearance, and seem- ing tendency in the direction towards which the spectator is looking, as the lines themselves. Thus in the Street View, the fronts of the houses seem to approach each other as they recede, tending inwards towards the prime vertical line, whilst the ground appears to rise upwards towards the horizontal line. This tendency of the ground to in- cline apparently upwards in the drawing is very remarkable in the view of Edinburgh, owing to the great elevation given to the horizon ; but Interiors exhibit the most complete elucidation of the principle, the ceilings presenting in addi- tion a level surface above the eye, which has the semblance of inclining downwards ; (for instance, the Interior in plate 3, from Da Vinci's celebrated picture of the Last Supper.") It will be here observed, by the way, that the upper and lower side lines, uniting the walls with the floor and ceiling in this example, going off direct from the eye, are common to both surfaces. If we now select any objects nearly level witli the eye, 16 VANISHING LINES. and having a number of flat surfaces of correspondent size at various distances, {seejigure 3 plate 2), it will be seen that as these surfaces approach the horizontal line their depths apparently contract, becoming narrower and nar- rower, so that when a surface is even with the eye, (in other words coincides with the horizontal line), as the top of the desk in the same figure, it disappears, or as it is termed, vanishes, leaving only its edge visible ; hence the horizon- tal line is said to be the vanishing line of level surfaces, seeing that as they approach it they gradually seem to les- sen, and finally disappear therein. There is one important circumstance to be remarked consequent upon the above variation in the appearance of these surfaces, viz., that the inclination or obliquity of their edges (when not parallel to the horizon) necessarily varies with the height of the surface. Thus in Jig. 3 it will be seen that the inclination of the sides of the shelves is greatest when they are far- thest removed from the horizon, and vice versa. An effect analogous to what we have just described, in reference to surfaces bounded by right lines, will be observed to take place with the Flower-stand, where we have a succession of circles situated horizontally; viz., the several ellipses which represent them will be seen to contract as they approach the horizon, the lowest one being fullest and roundest, the middle one materially less so, whilst the curvature of the uppermost one, from its being even with the eye, is entirely lost. Having determined the situation of objects in reference to the horizontal line, we have next to determine their situation in reference to the prime vertical line, and thereby fix their place in respect of the seat of the eye, or DISTANCE OF THE OBJECT ETC. 17 point formed by their intersection. For this purpose the attention of the student is called to the representation of a Book and a Hoop, (see plate 3), at different distances from the eye, and he will remark the analogy which they bear to figures 3 and 4 in the preceding plate ; the prime vertical line in this case being the vanishing line for upright sur- faces at right angles to the spectator, as the horizontal line in the former for level surfaces. This will be rendered manifest if, while looking at the example in question, we turn the book half round, so that the prime vertical line is brought into the horizontal jDosition. These two vanish- ing lines, having fixed places upon the drawing, will suffice for all the ordinary purposes of the sketcher, indeed they govern all others, and are the only ones introduced into the plates ; for, owing to the predominance of level surfaces in artificial objects, and next to them of upright ones, surfaces oblique to the eye, as the roofs of buildings, are never met with but in connection with one or other of the above, consequently the lines bounding them are common to both, and will have the same vanishing points. 2. — Distance of the Object from the Eye. Daily experience has familiarised us with the fact that all objects appear to diminish according to their remoteness from the spectator ; hence the smallness of the further edge of the Chess-board, and of the distant arch of the railway, and the far side of the apartment {plate 3). Such are amongst the most obvious effects of the above principle 18 POSITIONS OF THE SIDES OF as regards lines and surfaces square with the eye. But, once admitted, its consequences take place in every degree of distance ; and to its operation is to be traced every variation in the form of a surface inclining off from the spectator, the lessening of the parts as they recede neces- sarily causing the lines to tend towards each other. The Chess-board is a remarkable illustration : here we have a number of compartments perfectly uniform in size and figure in the real object, and not only do the several transverse rows of squares diminish as they recede, from the closing in of their side lines, but each separate square exhibits variations in form corresponding with that of the board. 3. — Positions of the Sides of the Object to the Spectator. Lastly, we have to consider the positions of the sides of the object in reference to the spectator. It will, however, be necessary previously to take into account the ordinary forms of buildings and other objects. These may be classed into, 1st, buildings, &c. of the ordinary square form, having their sides at right angles to each other; 2ndly, objects having more than four sides ; 3rdly, curved- lined objects. It is scarcely necessary to observe that by far the greater number of objects fall under the first of these divisions, and as it will be seen m the sequel that the correct delineation of the objects comprised under the second division may be most easily effected by referi'ino- THE OBJECT TO THE SPECTATOR. 19 them to the square form, it is to that class our attention will be chiefly directed. It will be readily admitted that the position of an object to the eye may be varied almost to infinity, yet there are but two positions which can be considered as distinct in kind from each other. Thus, in plate 4 are represented different views of the same small object : in the two upper views, one side is square to the spectator, preserving its true form and proportions; and the adjoining side, being at right angles to the former, goes off direct from the spectator. In the lower view, an angle or corner is towards us, and both sides are oblique to the spectator. To one or other of these two positions every object we can conceive (bounded by right lines) may be referred ; either one side will be square to, or both sides oblique to the spectator. The former position of the object is termed the Parallel View, its level lines in the near side retaining their parallel position to each other and to the horizon ; while the other position is denominated the Oblique View, all the lines (not upright) being oblique. The Chess-board, the Interior and the Street View are all examples of objects in the Parallel view ; the Observatory, of one in the Oblique view. Before selecting different varieties of objects singly and combined comprehended under one or other of these two classes, it will be desirable to compare them with each other, in order to exhibit more prominently the charac- teristics of each. 20 Chapter IV. The parallel and OBLIQUE VIEWS CONSIDERED. The Tea-chest selected for the special illustration of the two positions of objects described in the preceding section is of the cubic form — the form chiefly characteristic of buildings and other right-line objects, which have for the most part their lines and surfaces at right angles to each other ; and however irregular the external forms of many objects, they are more or less referable to this simple geometrical solid. The length merely of the lines can obviously be of no moment, for if the form of the object be extended vertically, by placing one cube over another, or laterally, by placing them side by side, the relative positions of their boundary lines remain unaltered. The parallel view is distinguished from the oblique view from the circumstance of there being only one vanishing point, and that point the seat of the eye ; whereas in the oblique view there are always two vanishing points ; again, by the direction of the sides of the object to the spectator. Thus the parallel view includes two out of the three positions of surfaces to the spectator enumerated in Chapter ii., viz., those square to the eye, and those going direct from it ; in the former case the surface retains its true form and PARALLEL AND OBLIQUE VIEWS. [Plate 4. PARALLEL AND OBLIQUE VIEWS ETC. 21 proportions (and hence it is oftentimes designated the geometrical view) ; in the latter, being seen sideways, it appears greatly foreshortened. In plate 4, two represen- tations of the Chest are given in the parallel view, shewing that it is by no means necessary that the object should be opposite to or facing us ; it may be situate at either side, as when other objects occupy the central space in the drawing. It is essentially necessary to be clear on this head. In the front row of squares in the Chess-board {plate 1) each square, taken separately, is in the parallel view no less than the board itself ; yet they differ most materially in appearance solely from difference of situation, some of them fronting us, others being at the sides. Turning now our attention to the lower view of the Chest, it will be seen that in consequence of that side going off from the eye which in the preceding figure was square to it, the top and bottom lines previously represented as horizontal now become oblique, converging to a point upon the horizontal line at some distance out of the drawing ; and consequent upon this change in the position of the object, the retiring lines of the shaded side converge to a second vanishing point to the right of the seat of the eye, which last point is not now required. The student will be careful to note that the lower retiring lines in all three of the views are considerably more oblique than the upper ones, being more remote from the hori- zontal line. The true direction of the retiring lines having been found, it only remains to determine the depths of the retiring sides, in order to the completion of the form of the object ; but unfortunately the rules of perspective for 22 PARALLEL AND OBLIQUE VIEWS ETC. marking off distances on receding lines are inapplicable in sketching from nature, and the student must depend for his guide on comparing the apparent width of the receding side with the width of the side square to the eye, bearing in mind that by giving too great a depth to the upper surface, the appearance of flatness will be destroyed. The view of the building in Hyde-Park, introduced at the bottom of the plate, offers a familiar example of the oblique view. Vast as is the scale of this structure, and multi- tudinous as are its parts, there are no more than two vanishing points required for the direction of its lines. The three tiers of walls exhibit very forcibly the conver- gence of the side lines to their respective points. 23 Chapter V. PARALLEL VIEW. On glancing over the objects represented in plate 6, it will be perceived that the rules laid down in the preceding chapter for delineating the simple form of the tea-chest, in the parallel view, apply equally for the representation of the main form or body of each of them, as these consist for the most part of horizontal or vertical lines, the difference being in the addition of certain portions sloping to the horizon; and as in out-door objects, such parts are chiefly to be met with in the roofs of buildings, w^e shall proceed to consider what may be termed Roof Lines. These parts of a building are often a matter of much per- plexity to the student, but if he will only be careful to note, in the first place, the position of the body of the building to the eye, (whether in the Parallel or Oblique view) and in the second place, remember that the lines which are parallel to each other must ever have the same vanishing point or point of convergence, the difficulty will cease. In the first and second illustrations at the head of the plate, two ordi- 24 ROOF LINES. nary forms of roofs are given, and the buildings being in the parallel view, the point of convergence in the slanting lines will be on the prime vertical line. Produce, therefore, the near side until it intersects this line, and make the off side {a) tend to the same point, or simply draw the line (a) tending inwards towards the other one, the inclination increasing with that of the roof itself In the other cottage, the row of lines in the roof wOl, by the same principle, con- verge to a point on the prime vertical line, and the apex be situate upon the central one. It is seldom necessary actually to mark this point upon the drawing ; their true place being kept in view, the hand will soon acquire the power of drawing such lines, taking the true course. The articles of furniture introduced in this place are examples that, notwithstanding the irregularities in their outlines, (of constant occurrence with such objects) the observant eye will quickly perceive, that the same principles we have described are in operation for the bearing of the different points or general tendency of the lines, and for the diminu- tion of the receding parts. The dotted lines in both examples shew the method of finding the place of the feet, such imaginary lines materially assisting the eye in deter- mining such points. The Terrace steps, in so far as it regards the oblique lines, is but another variety of the two first examples in the plate, their vanishing point being situate in the prime vertical line, and the same principle applies to ascents generally when in the Parallel view. Having shewn the application of the principles of per- spective to the representation of single objects, it will be necessary in the next place to consider forms in combi- nation. PARALLEL VIEW. [Plate 5. PAEALLEL VIEW. [Plate 6. I ROOF LINES. 25 The Oblique view is generally preferred to the Parallel for buildings in a landscape, especially if detached, not only from the circumstance of the lines presenting a more pleasing contrast to the eye, but as exhibiting the propor- tions and the dispositions of their parts to greater advan- tage. When, however, the buildings are principal, and extend to the sides or front of the drawing, as in plate 6, the Parallel view is best adapted. We have seen that when any number of lines in an object are parallel to each other, they converge to the same point ; this fact is so manifest, when ( as in the Chess-board, 2:)late 1 ) the lines lie near to each other, — that the merest tyro in the art can scarcely fail to observe it, no less than with the lines of the mouldings and windows &c. in the facades of the houses in the "Street View," {plate 2.) With the Tea-chest however, where the lines parallel to each other, as the above ones, are at some distance apart, their true direction would be less apparent. But when the lines of which we have been speaking are actually at oppo- site sides of the drawing, as we find them to be in figure 1, plate 6, the apparent course they take would be as difficult for the untutored eye to discover, as their actual position to each other. But the mere fact that the buildings are all in the parallel view, relieves us at once of our diffi- culty, since the retiring lines must all tend to the seat of the eye ; as for instance, the lines of the wall to the left of the pavement in front, and of the ballustrade, in common with the lines seen within the archway. The Terrace steps fur- nish an example of a descent or lines in a drawing inclining downwards, the treatment of which would correspond to that observed with the ascending steps in the preceding 26 INTERIORS. plate, only that the point to which the slanting lines would incline on the prime vertical line would be helow the horizon. Interiors. In interiors preference is always given to the Parallel view, especially where, as in historical subjects, the back- ground is of secondary interest, and variety in the lines is less called for. In the Cartoons of Raffaelle we find the expression of the subject heightened by the simple char- acter of the architecture ; the lines of the buildings con- sisting for the most part of horizontal and vertical lines. In the class of domestic subjects, and portraiture, it is seldom that (besides the floor) more than a portion of the end of a room and of one side are introduced, rarely the ceiling : hence, as in the plate, the Seat of the Eye is the vanishing point for lines in the floor, for carpet patterns and articles of furniture against the sides, or otherwise in the parallel view. 27 Chapter VI.* OBLIQUE VIEW. The appearance of the simple cottage-roof in the Oblique view is shewn in plate 1, the course of the lines corres- ponding Avith those in the moveable part of the Embroidery- frame and the lid of the Work-box. An open writing-desk, a swing dressing-glass, and a music-stand furnish other familiar examples, the principle being the same whatever the inclination of the surface ; the top and bottom lines tending to one of the two vanishing points upon the hori- zontal line, and the others to a point at some distance directly over it. It has not been judged necessary to intro- duce in the drawing the lines in which such points would be situated, as it would necessitate the introduction of new vanishing lines solely for them ; but if the student will, as directed with figures 1 and 2 in the preceding plate, make the off-edge {a) slightly incline towards the other one, the representation will be true to the appearance in nature. The row of tiles in the cottage-roof, running parallel to each other in nature, would in the same manner require to be made slightly converging as they ascend towards the ridge. In order to determine the true situation for the ridge of the roof, diagonals may be advantageously resorted to. 28 OBLIQUE VIEW. The use of these lines in finding the apparent centre of a surface of the ordinary square form, preparatory to drawing the middle line, is shewn in the Tea-chest, [flats 4) ; and on the same principle, in the example before us, it will be seen that the place for the line passing down the middle of the end of the Cottage is obtained, upon which the point of the gable will always be found. To insure accuracy, the end of the Cottage should be completed without the roof, as from its projection it will necessarily hide from view the nearest sloping lines. The sides of the Work-box inclining inwards, the corners could not be represented by upright lines, but each of them will have a different inclination, which must be drawn by hand ; — for the lid, proceed as for the cottage-roof; the lines forming the partitions would be drawn to the vanishing points on the horizontal line with the top and bottom lines. The top of the small Cabinet being only partially open, gives a case of a descending sur- face, like the oif-side of the cottage-roof ; the lines of the sides w^ould in consequence converge to a point below the Horizontal line, directly under the vanishing point. The top and bottom line of the doors of the cabinet being level, would tend to points on the horizontal line, to be deter- mined by producing the lower ones until they intersect it : these lower lines should be carefully drawn in by the eye, and then the upper ones, tending to the point found as above. The same method would be adopted in representing the open doors of an apartment, as also a folding screen. Plate 8 represents two views of the same building, a Vil- lage Church, taken from the " Folding Drawing Models,"-^ * Sold by Messrs. Rowney and Co. OBLIQUE YIEW. [Plate 8. OBLIQUE VIEW. 29 and is one of the class of subjects so frequently selected by the amateur. The upper one exhibits the main features of the building as a preparatory sketch, without buttresses, spire and accompaniments ; and hence it is better adapted for exhibiting the course of the oblique lines. Although this portion of the building consists of three or more parts, the inclined lines, with the exception of the roof-lines, tend only to two points in the horizontal line, like the lines in the oblique view of the Tea-chest, {plate 4) ; indeed the lower ones can seldom be traced, being concealed by the broken ground, weeds, &c. The roof-lines present the chief difficulty, but if the instructions given in the fore- going page have been clearly comprehended, the opera- tion of the principle for the double roof and the roof of the porch will be easily traced : it may suffice to observe, that the two vanishing points for these lines lie imme- diately over the vanishing point for the side of the building. In the lower view, the sloping surfaces of the corner but- tresses and of the spire are oblique to the spectator, but, from their small size, their forms may be safely drawn in by the eye. c 30 Chapter VII. OBJECTS HAVING MORE THAN FOUR SIDES. In out-door objects, these consist for the most part of the towers of castles, those flanking gateways of the tudor period, church-spires, and the light ornamental structures in pleasure grounds, as summer-houses, alcoves, &c. The number of their sides generally vary from six to eight; and it has been customary in delineating them to resolve them into four-sided figures, by producing two or more of their sides, as in the following diagram; then proceeding as before OBJECTS HAVING MORE THAN FOUR SIDES. 31 But in free-hand drawing this practice may be dispensed with; it will be advantageous, however, (with the former especially) to keep in view the analogy between them and the square, as it will be seen that there are many lines common to both figures to which the same rules apply. The parallel view is usually preferred to the oblique view for single objects of this class, as offering more contrast in the lines, with greater simplicity; also as rendering their form more evident to the eye. On examining the first of the above diagrams, disposed towards the spectator as figures 1 and 2 {plate 9), it will be seen that there w^ould be three vanishing points, one being the seat of the eye, viz., that for the lines in the dark side of the Towers and edges to right and left of the Table, whilst two of the oblique sides, being opposite and parallel to the other two, would form vanishing points on the horizontal line ; also these sides being equally inclined in nature to the spectator, the points of convergence would be equally distant from the seat of the eye. In figure 2, one of these vanishing points for the sides of the table (oblique to the spectator) comes into the plate at the left-hand comer, the other one being situated at the same distance from the seat of the eye at the oppo- site side, and therefore easily found, if required for greater accuracy. The castellated building {figure 1 ) being situated considerably to the left of the spectator, and representing only a portion of the entire subject, the seat of the eye does not come within the plate. The Summer-house, another illustration selected from the " Folding Drawing Models," is an example of a six- sided building, and as on referring to the diagram there are no sides at right angles, or going direct from the spec- 32 OBJECTS HAVING MORE THAN FOUR SIDES. tator, the seat of the eye is not wanted in drawing the roof and sides of the building, but only for the lower portion or platform which is square. The lines of the receding sides would tend to points on either side of the seat of the eye, and as in the former case be equally distant therefrom. The above forms often meet the eye in the oblique view when in connection with buildings so situated, in which case some of the sides will have the same vanishing points as the building itself The " Concertina*' is in the oblique view, so that the row of parallel lines contained in it would, so situated, gradually lessen as they recede from the eye, together with the line forming the end of the object, thereby causing the diminution observable in the off side of it. 33 Chapter VIIL CURVED-LINED OBJECTS. The appearance of curved lines has been already alluded to in Chapter L, where it was shewn that they have, equally with right lines^, the property of seeming in nature to tend towards the point to which the eye of the spectator is bent ; and thus, if situated horizontally to, incline towards the horizontal line, or if vertically (-and at right angles to the spectator) towards the prime vertical line. But there is another property necessarily resulting from the above one, viz., inequality of curvature; the same curved line appearing in one point of view round and full, at another nearly straight. The curved lines we have to consider are chiefly those of the circle in the horizontal position, the sections of it occurring in arches, and the pointed arch, forming a dis- tinct class of curved lines.

CAUTION. The Public are respectfully requested to observe that the name of " George Rowney and Compy'^ is stamped on each Pencil ; as their unpre- cedented success has induced other manufacturers to imitate them in their outward appearance, as the means of selling an inferior article, to the injury of the character established by Messrs. R. and Co. for their Pencils. 6 EOYAL ACADEMY CRAYONS, MANUFACTURED ONLY BY GEO. EOWNEY & CO., The great desideratum in Black Drawing Chalks is to obtain a material that will work freely and pleasantly without coarseness or grit, having great depth of colour in the softest degree, and a more delicate shade of black for the harder degrees. The Royal Academy Crayons possess these properties to a degree far beyond any other Crayons hitherto manufactured, being perfectly free from grit, working smoothly and freely, like the Italian Chalk ; and while possessing equal depth with the Conte Crayons, have all the delicacy and fineness of a Black Lead Pencil. The Royal Academy Crayons have met with very general approval, and have been adopted by all the Schools of Design and Drawing Academies in which they have been introduced. The following Testimonials, selected from among numerous others, are respectfully submitted. Government School of Design, Somerset House, "June 1, 1850. " Mr. Herman presents his compliments to Messrs. Rowney, aud begs to thank them for the specimen sent of their Academy Crayons, which he has for some time past been in the habit of using for Sketching, for which they are particularly adapted, and has, therefore, great pleasure in testifying to their merits." "46, Great Camden Street, Camden Town, " May 11th, 1850. " Mr. R. W. Buss has tested the Black Crayons manufactured by Messrs. Rowney and Co., and can state with confidence that the preparation is a decided improvement upon the well-know French Conte Crayons, as the Black Crayons of Messrs. Rowney and Co. are deep in colour, free from grit, and work as smoothly as Black Italian Chalk, which latter quality Mr. Buss finds of great importance in liis classes for Drawing from Nature Delicate half-tints are also more easily obtained by means of these Crayons than by the Conte Chalks." From H. O'Neil's Guide to Pictorial Art. " The Royal Academy Chalk works very like the Italian, but is better in colour. This is the cheapest and best Chalk in use."
