The Practice and Science of Drawing

If we call these variations from a common type in the features imperfections, as it is usual to do, it would seem to be the imperfections of perfection that charm and stir us; and that perfection without these so-called imperfections is a cold, dead abstraction, devoid of life: that unity without variety is lifeless and incapable of touching us. On the other hand, variety without unity to govern it is a riotous exuberance of life, lacking all power and restraint and wasting itself in a madness of excess. So that in art a balance has to be struck between these two opposing qualities. In good work unity is the dominating quality, all the variety being done in conformity to some large idea of the whole, which is never lost sight of, even in the smallest detail of the work. Good style in art has been defined as "variety in unity," and Hogarth's definition of composition as the art of "varying well" is similar. And I am not sure that "contrasts in harmony" would not be a suggestive definition of good colour. Let us consider first variety and unity as they are related to line drawing, and afterwards to mass drawing. XI RHYTHM: VARIETY OF LINE Line rhythm or music depends on the shape of your lines, their relation to each other and their relation to the boundaries of your panel. In all good work this music of line is in harmony with the subject (the artistic intention) of your picture or drawing. The two lines with the least variation are a perfectly straight line and a circle. A perfectly straight line has obviously no variety at all, while a circle, by curving at exactly the same ratio all along, has no variation of curvature, it is of all curves the one with the least possible variety. These two lines are, therefore, two of the dullest, and are seldom used in pictures except to enhance the beauty and variety of others. And even then, subtle variations, some amount of play, is introduced to relieve their baldness. But used in this way, vertical and horizontal lines are of the utmost value in rectangular pictures, uniting the composition to its bounding lines by their parallel relationship with them. And further, as a contrast to the richness and beauty of curves they are of great value, and are constantly used for this purpose. The group of mouldings cutting against the head in a portrait, or the lines of a column used to accentuate the curved forms of a face or figure, are well-known instances; and the portrait painter is always on the look out for an object in his background that will give him such straight lines. You may notice, too, how the lines drawn across a study in order to copy it (squaring it out, as it is called) improve the look of a drawing, giving a greater beauty to the variety of the curves by contrast with the variety lacking in straight lines. The perfect curve of the circle should always be avoided in the drawing of natural objects (even a full moon), and in vital drawings of any sort some variety should always be looked for. Neither should the modelling of the sphere ever occur in your work, the dullest of all curved surfaces. Although the curve of the perfect circle is dull from its lack of variety, it is not without beauty, and this is due to its perfect unity. It is of all curves the most perfect example of static unity. Without the excitement of the slightest variation it goes on and on for ever. This is, no doubt, the reason why it was early chosen as a symbol of Eternity, and certainly no more perfect symbol could be found. The circle seen in perspective assumes the more beautiful curve of the ellipse, a curve having much variety; but as its four quarters are alike, not so much as a symmetrical figure can have. Perhaps the most beautiful symmetrically curved figure of all is the so-called egg of the well-known moulding from such a temple as the Erechtheum, called the egg and dart moulding. Here we have a perfect balance between variety and unity. The curvature is varied to an infinite degree, at no point is its curving at the same ratio as at any other point; perhaps the maximum amount of variety that can be got in a symmetrical figure, preserving, as it does, its almost perfect continuity, for it approaches the circle in the even flow of its curvature. This is, roughly, the line of the contour of a face, and you may note how much painters who have excelled in grace have insisted on it in their portraits. Gainsborough and Vandyke are striking, instances. [Illustration: Diagram VII. EGG AND DART MOULDING FROM ONE OF THE CARYATIDES FROM THE ERECHTHEUM IN THE BRITISH MUSEUM] The line of a profile is often one of great beauty, only here the variety is apt to overbalance the unity or run of the line. The most beautiful profiles are usually those in which variety is subordinated to the unity of the contour. I fancy the Greeks felt this when they did away with the hollow above the nose, making the line of the forehead run, with but little interruption, to the tip of the nose. The unity of line is increased, and the variety made more interesting. The idea that this was the common Greek type is, I should imagine, untrue, for their portrait statues do not show it. It does occur in nature at rare intervals, and in most Western nationalities, but I do not think there is much evidence of its ever having been a common type anywhere. [Illustration: Diagram VIII. ILLUSTRATING VARIETY IN SYMMETRY Note how the hollows marked A are opposed by fullnesses marked B.] In drawing or painting a profile this run or unity of the line is the thing to feel, if you would express its particular beauty. This is best done in the case of a painting by finally drawing it with the brush from the background side, after having painted all the variety there is of tone and colour on the face side of the line. As the background usually varies little, the swing of the brush is not hampered on this side as it is on the other. I have seen students worried to distraction trying to paint the profile line from the face side, fearing to lose the drawing by going over the edge. With the edge blurred out from the face side, it is easy to come with a brush full of the colour the background is immediately against the face (a different colour usually from what it is further away), and draw it with some decision and conviction, care being taken to note all the variations on the edge, where the sharpnesses come and where the edge is more lost, &c. [Sidenote: Variety in Symmetry.] The contours of the limbs illustrate another form of line variety--what may be called "Variety in Symmetry." While roughly speaking the limbs are symmetrical, each side not only has variety in itself, but there is usually variety of opposition. Supposing there is a convex curve on the one side, you will often have a concave form on the other. Always look out for this in drawing limbs, and it will often improve a poorly drawn part if more of this variation on symmetry is discovered. The whole body, you may say, is symmetrical, but even here natural conditions make for variety. The body is seldom, except in soldiering, held in a symmetrical position. The slightest action produces the variety we are speaking about. The accompanying sketches will indicate what is meant. [Illustration: Diagram IX. ILLUSTRATING VARIETY IN SYMMETRY Note how the hollows marked A are opposed by the fullnesses marked B.] Of course the student, if he has any natural ability, instinctively looks out for all these variations that give the play of life to his drawing. It is not for him in the full vigour of inspiration that books such as this are written. But there may come a time when things "won't come," and it is then that it is useful to know where to look for possible weak spots in your work. [Sidenote: Variety of Thickness and Accent.] A line of equal thickness is a very dead and inexpressive thing compared with one varied and stressed at certain points. If you observe any of the boundaries in nature we use a line to express, you will notice some points are accentuated, attract the attention, more than others. The only means you have to express this in a line drawing is by darkening and sharpening the line. At other points, where the contour is almost lost, the line can be soft and blurred. It is impossible to write of the infinite qualities of variety that a fine draughtsman will get into his line work; they must be studied first hand. But on this play of thickness and quality of line much of the vitality of your drawing will depend. XII RHYTHM: UNITY OF LINE Unity of line is a bigger quality than variety, and as it requires a larger mental grasp, is more rarely met with. The bigger things in drawing and design come under its consideration, including, as it does, the relation of the parts to the whole. Its proper consideration would take us into the whole field of Composition, a subject needing far more consideration than it can be given in this book. In almost all compositions a rhythmic flow of lines can be traced. Not necessarily a flow of actual lines (although these often exist); they may be only imaginary lines linking up or massing certain parts, and bringing them into conformity with the rhythmic conception of the whole. Or again, only a certain stress and flow in the forms, suggesting line movements. But these line movements flowing through your panel are of the utmost importance; they are like the melodies and subjects of a musical symphony, weaving through and linking up the whole composition. Often, the line of a contour at one part of a picture is picked up again by the contour of some object at another part of the composition, and although no actual line connects them, a unity is thus set up between them. (See diagrams, pages 166 and 168, illustrating line compositions of pictures by Botticelli and Paolo Veronese). This imaginary following through of contours across spaces in a composition should always be looked out for and sought after, as nothing serves to unite a picture like this relationship of remote parts. The flow of these lines will depend on the nature of the subject: they will be more gracious and easy, or more vigorous and powerful, according to the demands of your subject. This linking up of the contours applies equally well to the drawing of a single figure or even a head or hand, and the student should always be on the look out for this uniting quality. It is a quality of great importance in giving unity to a composition. [Sidenote: Parallelism] When groups of lines in a picture occur parallel to each other they produce an accentuation of the particular quality the line may contain, a sort of sustained effect, like a sustained chord on an organ, the effect of which is much bigger than that of the same chord struck staccato. This sustained quality has a wonderful influence in steadying and uniting your work. This parallelism can only be used successfully with the simplest lines, such as a straight line or a simple curve; it is never advisable except in decorative patterns to be used with complicated shapes. Blake is very fond of the sustained effect parallelism gives, and uses the repetition of curved and straight lines very often in his compositions. Note in Plate I of the Job series, page 146 [Transcribers Note: Plate XXXI], the use made of this sustaining quality in the parallelism of the sheep's backs in the background and the parallel upward flow of the lines of the figures. In Plate II you see it used in the curved lines of the figures on either side of the throne above, and in the two angels with the scroll at the left-hand corner. Behind these two figures you again have its use accentuating by repetition the peaceful line of the hacks of the sheep. The same thing can be seen in Plate XXXI, B, where the parallelism of the back lines of the sheep and the legs of the seated figures gives a look of peace contrasting with the violence of the messenger come to tell of the destruction of Job's sons. The emphasis that parallelism gives to the music of particular lines is well illustrated in all Blake's work. He is a mine of information on the subject of line rhythm. Compare A with Plate XXXI, C; note how the emotional quality is dependent in both cases on the parallelism of the upward flow of the lines. How also in Plate I he has carried the vertical feeling even into the sheep in the front, introducing little bands of vertical shading to carry through the vertical lines made by the kneeling figures. And in the last plate, "So the Lord blessed the latter end of Job more than the beginning," note how the greater completeness with which the parallelism has been carried out has given a much greater emphasis to the effect, expressing a greater exaltation and peace than in Plate XXXI, A. Notice in Plate XXXI, D, where "The just, upright man is laughed to scorn," how this power of emphasis is used to increase the look of scorn hurled at Job by the pointing fingers of his three friends.
