The Crown of Wild Olive

160. Next to the colour, the fineness of substance which will take a perfectly sharp edge, is essential; and this not merely to admit fine delineation in the sculpture itself, but to secure a delightful precision in placing the blocks of which it is composed. For the possession of too fine marble, as far as regards the work itself, is a temptation instead of an advantage to an inferior sculptor; and the abuse of the facility of undercutting, especially of undercutting so as to leave profiles defined by an edge against shadow, is one of the chief causes of decline of style in such encrusted bas-reliefs as those of the Certosa of Pavia and its contemporary monuments. But no undue temptation ever exists as to the fineness of block fitting; nothing contributes to give so pure and healthy a tone to sculpture as the attention of the builder to the jointing of his stones; and his having both the power to make them fit so perfectly as not to admit of the slightest portion of cement showing externally, and the skill to insure, if needful, and to suggest always, their stability in cementless construction. Plate X. represents a piece of entirely fine Lombardic building, the central portion of the arch in the Duomo of Verona, which corresponds to that of the porch of San Zenone, represented in Plate I. In both these pieces of building, the only line that traces the architrave round the arch, is that of the masonry joint; yet this line is drawn with extremest subtlety, with intention of delighting the eye by its relation of varied curvature to the arch itself; and it is just as much considered as the finest pen-line of a Raphael drawing. Every joint of the stone is used, in like manner, as a thin black line, which the slightest sign of cement would spoil like a blot. And so proud is the builder of his fine jointing, and so fearless of any distortion or strain spoiling the adjustment afterwards, that in one place he runs his joint quite gratuitously through a bas-relief, and gives the keystone its only sign of pre-eminence by the minute inlaying of the head of the Lamb, into the stone of the course above.

161. Proceeding from this fine jointing to fine draughtsmanship, you have, in the very outset and earliest stage of sculpture, your flat stone surface given you as a sheet of white paper, on which you are required to produce the utmost effect you can with the simplest means, cutting away as little of the stone as may be, to save both time and trouble; and, above all, leaving the block itself, when shaped, as solid as you can, that its surface may better resist weather, and the carved parts be as much protected as possible by the masses left around them.

162. The first thing to be done is clearly to trace the outline of subject with an incision approximating in section to that of the furrow of a plough, only more equal-sided. A fine sculptor strikes it, as his chisel leans, freely, on marble; an Egyptian, in hard rock, cuts it sharp, as in cuneiform inscriptions. In any case, you have a result somewhat like the upper figure, Plate XI., in which I show you the most elementary indication of form possible, by cutting the outline of the typical archaic Greek head with an incision like that of a Greek triglyph, only not so precise in edge or slope, as it is to be modified afterwards.

163. Now, the simplest thing we can do next, is to round off the flat surface within the incision, and put what form we can get into the feebler projection of it thus obtained. The Egyptians do this, often with exquisite skill, and then, as I showed you in a former lecture, colour the whole—using the incision as an outline. Such a method of treatment is capable of good service in representing, at little cost of pains, subjects in distant effect, and common, or merely picturesque, subjects even near. To show you what it is capable of, and what coloured sculpture would be in its rudest type, I have prepared the coloured relief of the John Dory[129 - This relief is now among the other casts which I have placed in the lower school in the University galleries.] as a natural history drawing for distant effect. You know, also, that I meant him to be ugly—as ugly as any creature can well be. In time, I hope to show you prettier things—peacocks and kingfishers,—butterflies and flowers, on grounds of gold, and the like, as they were in Byzantine work. I shall expect you, in right use of your æsthetic faculties, to like those better than what I show you to-day. But it is now a question of method only; and if you will look, after the lecture, first at the mere white relief, and then see how much may be gained by a few dashes of colour, such as a practised workman could lay in a quarter of an hour,—the whole forming, if well done, almost a deceptive image—you will, at least, have the range of power in Egyptian sculpture clearly expressed to you.

164. But for fine sculpture, we must advance by far other methods. If we carve the subject with real delicacy, the cast shadow of the incision will interfere with its outline, so that, for representation of beautiful things, you must clear away the ground about it, at all events for a little distance. As the law of work is to use the least pains possible, you clear it only just as far back as you need, and then for the sake of order and finish, you give the space a geometrical outline. By taking, in this case, the simplest I can,—a circle,—I can clear the head with little labor in the removal of surface round it; (see the lower figure in Plate XI.)

165. Now, these are the first terms of all well-constructed bas-relief. The mass you have to treat consists of a piece of stone, which, however you afterwards carve it, can but, at its most projecting point, reach the level of the external plane surface out of which it was mapped, and defined by a depression round it; that depression being at first a mere trench, then a moat of certain width, of which the outer sloping bank is in contact, as a limiting geometrical line, with the laterally salient portions of sculpture. This, I repeat, is the primal construction of good bas-relief, implying, first, perfect protection to its surface from any transverse blow, and a geometrically limited space to be occupied by the design, into which it shall pleasantly (and as you shall ultimately see, ingeniously,) contract itself: implying, secondly, a determined depth of projection, which it shall rarely reach, and never exceed: and implying, finally, the production of the whole piece with the least possible labor of chisel and loss of stone.

166. And these, which are the first, are very nearly the last constructive laws of sculpture. You will be surprised to find how much they include, and how much of minor propriety in treatment their observance involves.

In a very interesting essay on the architecture of the Parthenon, by the professor of architecture of the Ecole Polytechnique, M. Emile Boutmy, you will find it noticed that the Greeks do not usually weaken, by carving, the constructive masses of their building; but put their chief sculpture in the empty spaces between the triglyphs, or beneath the roof. This is true; but in so doing, they merely build their panel instead of carving it; they accept no less than the Goths, the laws of recess and limitation, as being vital to the safety and dignity of their design; and their noblest recumbent statues are, constructively, the fillings of the acute extremity of a panel in the form of an obtusely summitted triangle.

167. In gradual descent from that severest type, you will find that an immense quantity of sculpture of all times and styles may be generally embraced under the notion of a mass hewn out of, or, at least, placed in, a panel or recess, deepening, it may be, into a niche; the sculpture being always designed with reference to its position in such recess; and, therefore, to the effect of the building out of which the recess is hewn.

But, for the sake of simplifying our inquiry, I will at first suppose no surrounding protective ledge to exist, and that the area of stone we have to deal with is simply a flat slab, extant from a flat surface depressed all round it.

168. A flat slab, observe. The flatness of surface is essential to the problem of bas-relief. The lateral limit of the panel may, or may not, be required; but the vertical limit of surface must be expressed; and the art of bas-relief is to give the effect of true form on that condition. For observe, if nothing more were needed than to make first a cast of a solid form, then cut it in half, and apply the half of it to the flat surface;—if, for instance, to carve a bas-relief of an apple, all I had to do was to cut my sculpture of the whole apple in half, and pin it to the wall, any ordinary trained sculptor, or even a mechanical workman, could produce bas-relief; but the business is to carve a round thing out of flat thing; to carve an apple out of a biscuit!—to conquer, as a subtle Florentine has here conquered,[130 - The reference is to a cast from a small and low relief of Florentine work in the Kensington Museum.] his marble, so as not only to get motion into what is most rigidly fixed, but to get boundlessness into what is most narrowly bounded; and carve Madonna and Child, rolling clouds, flying angels, and space of heavenly air behind all, out of a film of stone not the third of an inch thick where it is thickest.

169. Carried, however, to such a degree of subtlety as this, and with so ambitious and extravagant aim, bas-relief becomes a tour-de-force; and, you know, I have just told you all tours-de-force are wrong. The true law of bas-relief is to begin with a depth of incision proportioned justly to the distance of the observer and the character of the subject, and out of that rationally determined depth, neither increased for ostentation of effect, nor diminished for ostentation of skill, to do the utmost that will be easily visible to an observer, supposing him to give an average human amount of attention, but not to peer into, or critically scrutinize the work.

170. I cannot arrest you to-day by the statement of any of the laws of sight and distance which determine the proper depth of bas-relief. Suppose that depth fixed; then observe what a pretty problem, or, rather, continually varying cluster of problems, will be offered to us. You might, at first, imagine that, given what we may call our scale of solidity, or scale of depth, the diminution from nature would be in regular proportion, as for instance, if the real depth of your subject be, suppose a foot, and the depth of your bas-relief an inch, then the parts of the real subject which were six inches round the side of it would be carved, you might imagine, at the depth of half-an-inch, and so the whole thing mechanically reduced to scale. But not a bit of it. Here is a Greek bas-relief of a chariot with two horses (upper figure, Plate XXI). Your whole subject has therefore the depth of two horses side by side, say six or eight feet. Your bas-relief has, on the scale,[131 - The actual bas-relief is on a coin, and the projection not above the twentieth of an inch, but I magnified it in photograph, for this Lecture, so as to represent a relief with about the third of an inch for maximum projection.] say the depth of the third of an inch. Now, if you gave only the sixth of an inch for the depth of the off horse, and, dividing him again, only the twelfth of an inch for that of each foreleg, you would make him look a mile away from the other, and his own forelegs a mile apart. Actually, the Greek has made the near leg of the off horse project much beyond the off leg of the near horse; and has put nearly the whole depth and power of his relief into the breast of the off horse, while for the whole distance from the head of the nearest to the neck of the other, he has allowed himself only a shallow line; knowing that, if he deepened that, he would give the nearest horse the look of having a thick nose; whereas, by keeping that line down, he has not only made the head itself more delicate, but detached it from the other by giving no cast shadow, and left the shadow below to serve for thickness of breast, cutting it as sharp down as he possibly can, to make it bolder.

171. Here is a fine piece of business we have got into!—even supposing that all this selection and adaptation were to be contrived under constant laws, and related only to the expression of given forms. But the Greek sculptor, all this while, is not only debating and deciding how to show what he wants, but, much more, debating and deciding what, as he can't show everything, he will choose to show at all. Thus, being himself interested, and supposing that you will be, in the manner of the driving, he takes great pains to carve the reins, to show you where they are knotted, and how they are fastened round the driver's waist (you recollect how Hippolytus was lost by doing that), but he does not care the least bit about the chariot, and having rather more geometry than he likes in the cross and circle of one wheel of it, entirely omits the other!

172. I think you must see by this time that the sculptor's is not quite a trade which you can teach like brickmaking; nor its produce an article of which you can supply any quantity "demanded" for the next railroad waiting-room. It may perhaps, indeed, seem to you that, in the difficulties thus presented by it, bas-relief involves more direct exertion of intellect than finished solid sculpture. It is not so, however. The questions involved by bas-relief are of a more curious and amusing kind, requiring great variety of expedients; though none except such as a true workmanly instinct delights in inventing and invents easily; but design in solid sculpture involves considerations of weight in mass, of balance, of perspective and opposition, in projecting forms, and of restraint for those which must not project, such as none but the greatest masters have ever completely solved; and they, not always; the difficulty of arranging the composition so as to be agreeable from points of view on all sides of it, being, itself, arduous enough.

173. Thus far, I have been speaking only of the laws of structure relating to the projection of the mass which becomes itself the sculpture. Another most interesting group of constructive laws governs its relation to the line that contains or defines it.

In your Standard Series I have placed a photograph of the south transept of Rouen Cathedral. Strictly speaking, all standards of Gothic are of the thirteenth century; but, in the fourteenth, certain qualities of richness are obtained by the diminution of restraint; out of which we must choose what is best in their kinds. The pedestals of the statues which once occupied the lateral recesses are, as you see, covered with groups of figures, enclosed each in a quatrefoil panel; the spaces between this panel and the enclosing square being filled with sculptures of animals.

You cannot anywhere find a more lovely piece of fancy, or more illustrative of the quantity of result that may be obtained with low and simple chiselling. The figures are all perfectly simple in drapery, the story told by lines of action only in the main group, no accessories being admitted. There is no undercutting anywhere, nor exhibition of technical skill, but the fondest and tenderest appliance of it; and one of the principal charms of the whole is the adaptation of every subject to its quaint limit. The tale must be told within the four petals of the quatrefoil, and the wildest and playfullest beasts must never come out of their narrow corners. The attention with which spaces of this kind are filled by the Gothic designers is not merely a beautiful compliance with architectural requirements, but a definite assertion of their delight in the restraint of law; for, in illuminating books, although, if they chose it, they might have designed floral ornaments, as we now usually do, rambling loosely over the leaves, and although, in later works, such license is often taken by them, in all books of the fine time the wandering tendrils are enclosed by limits approximately rectilinear, and in gracefullest branching often detach themselves from the right line only by curvature of extreme severity.

174 Since the darkness and extent of shadow by which the sculpture is relieved necessarily vary with the depth of the recess, there arise a series of problems, in deciding which the wholesome desire for emphasis by means of shadow is too often exaggerated by the ambition of the sculptor to show his skill in undercutting. The extreme of vulgarity is usually reached when the entire bas-relief is cut hollow underneath, as in much Indian and Chinese work, so as to relieve its forms against an absolute darkness; but no formal law can ever be given; for exactly the same thing may be beautifully done for a wise purpose, by one person, which is basely done, and to no purpose, or to a bad one, by another. Thus, the desire for emphasis itself may be the craving of a deadened imagination, or the passion of a vigorous one; and relief against shadow may be sought by one man only for sensation, and by another for intelligibility. John of Pisa undercuts fiercely, in order to bring out the vigour of life which no level contour could render; the Lombardi of Venice undercut delicately, in order to obtain beautiful lines, and edges of faultless precision; but the base Indian craftsmen undercut only that people may wonder how the chiselling was done through the holes, or that they may see every monster white against black.

175. Yet, here again we are met by another necessity for discrimination. There may be a true delight in the inlaying of white on dark, as there is a true delight in vigorous rounding. Nevertheless, the general law is always, that, the lighter the incisions, and the broader the surface, the grander, cæteris paribus, will be the work. Of the structural terms of that work you now know enough to understand that the schools of good sculpture, considered in relation to projection, divide themselves into four entirely distinct groups:—

1st. Flat Relief, in which the surface is, in many places, absolutely flat; and the expression depends greatly on the lines of its outer contour, and on fine incisions within them.

2nd. Round Relief, in which, as in the best coins, the sculptured mass projects so as to be capable of complete modulation into form, but is not anywhere undercut. The formation of a coin by the blow of a die necessitates, of course, the severest obedience to this law.

3rd. Edged Relief. Undercutting admitted, so as to throw out the forms against a background of shadow.

4th. Full Relief. The statue completely solid in form, and unreduced in retreating depth of it, yet connected locally with some definite part of the building, so as to be still dependent on the shadow of its background and direction of protective line.

176. Let me recommend you at once to take what pains may be needful to enable you to distinguish these four kinds of sculpture, for the distinctions between them are not founded on mere differences in gradation of depth. They are truly four species, or orders, of sculpture, separated from each other by determined characters. I have used, you may have noted, hitherto in my Lectures, the word "bas-relief" almost indiscriminately for all, because the degree of lowness or highness of relief is not the question, but the method of relief. Observe again, therefore—

A. If a portion of the surface is absolutely flat, you have the first order—Flat Relief.

B. If every portion of the surface is rounded, but none undercut, you have Round Relief—essentially that of seals and coins.

C. If any part of the edges be undercut, but the general projection of solid form reduced, you have what I think you may conveniently call Foliate Relief,—the parts of the design overlapping each other in places, like edges of leaves.

D. If the undercutting is bold and deep, and the projection of solid form unreduced, you have full relief.

Learn these four names at once by heart:—

Flat Relief.
Round Relief.
Foliate Relief.
Full Relief.

And whenever you look at any piece of sculpture, determine first to which of these classes it belongs; and then consider how the sculptor has treated it with reference to the necessary structure—that reference, remember, being partly to the mechanical conditions of the material, partly to the means of light and shade at his command.

Plate XII.—Branch of Phillyrea. Dark Purple

177. To take a single instance. You know, for these many years, I have been telling our architects with all the force of voice I had in me, that they could design nothing until they could carve natural forms rightly. Many imagine that work was easy; but judge for yourselves whether it be or not. In Plate XII., I have drawn, with approximate accuracy, a cluster of Phillyrea leaves as they grow. Now, if we wanted to cut them in bas-relief, the first thing we should have to consider would be the position of their outline on the marble;—here it is, as far down as the spring of the leaves. But do you suppose that is what an ordinary sculptor could either lay for his first sketch, or contemplate as a limit to be worked down to? Then consider how the interlacing and springing of the leaves can be expressed within this outline. It must be done by leaving such projection in the marble as will take the light in the same proportion as the drawing does;—and a Florentine workman could do it, for close sight, without driving one incision deeper, or raising a single surface higher, than the eighth of an inch. Indeed, no sculptor of the finest time would design such a complex cluster of leaves as this, except for bronze or iron work; they would take simpler contours for marble; but the laws of treatment would, under these conditions, remain just as strict: and you may, perhaps, believe me now when I tell you that, in any piece of fine structural sculpture by the great masters, there is more subtlety and noble obedience to lovely laws than could be explained to you if I took twenty lectures to do it in, instead of one.

Fig. 9.

178. There remains yet a point of mechanical treatment, on which I have not yet touched at all; nor that the least important,—namely, the actual method and style of handling. A great sculptor uses his tools exactly as a painter his pencil, and you may recognize the decision of his thought, and glow of his temper, no less in the workmanship than the design. The modern system of modelling the work in clay, getting it into form by machinery, and by the hands of subordinates, and touching it at last, if indeed the (so called) sculptor touch it at all, only to correct their inefficiencies, renders the production of good work in marble a physical impossibility. The first result of it is that the sculptor thinks in clay instead of marble, and loses his instinctive sense of the proper treatment of a brittle substance. The second is that neither he nor the public recognize the touch of the chisel as expressive of personal feeling or power, and that nothing is looked for except mechanical polish.

179. The perfectly simple piece of Greek relief represented in Plate XIII., will enable you to understand at once,—examination of the original, at your leisure, will prevent you, I trust, from ever forgetting—what is meant by the virtue of handling in sculpture.

Plate XIII.—Greek Flat Relief and Sculpture by Edged Incision.

The projection of the heads of the four horses, one behind the other, is certainly not more, altogether, than three-quarters of an inch from the flat ground, and the one in front does not in reality project more than the one behind it, yet, by mere drawing,[132 - This plate has been executed from a drawing by Mr. Burgess, in which he has followed the curves of incision with exquisite care, and preserved the effect of the surface of the stone, where a photograph would have lost it by exaggerating accidental stains.] you see the sculptor has got them to appear to recede in due order, and by the soft rounding of the flesh surfaces, and modulation of the veins, he has taken away all look of flatness from the necks. He has drawn the eyes and nostrils with dark incision, careful as the finest touches of a painter's pencil: and then, at last, when he comes to the manes, he has let fly hand and chisel with their full force, and where a base workman, (above all, if he had modelled the thing in clay first,) would have lost himself in laborious imitation of hair, the Greek has struck the tresses out with angular incisions, deep driven, every one in appointed place and deliberate curve, yet flowing so free under his noble hand that you cannot alter, without harm, the bending of any single ridge, nor contract, nor extend, a point of them. And if you will look back to Plate IX. you will see the difference between this sharp incision, used to express horse-hair, and the soft incision with intervening rounded ridge, used to express the hair of Apollo Chrysocomes; and, beneath, the obliquely ridged incision used to express the plumes of his swan; in both these cases the handling being much more slow, because the engraving is in metal; but the structural importance of incision, as the means of effect, never lost sight of. Finally, here are two actual examples of the work in marble of the two great schools of the world; one, a little Fortune, standing tiptoe on the globe of the Earth, its surface traced with lines in hexagons; not chaotic under Fortune's feet; Greek, this, and by a trained workman;—dug up in the temple of Neptune at Corfu;—and here, a Florentine portrait-marble, found in the recent alterations, face downwards, under the pavement of St

Maria Novella;[133 - These two marbles will always, henceforward, be sufficiently accessible for reference in my room at Corpus Christi College.] both of them first-rate of their kind; and both of them, while exquisitely finished at the telling points, showing, on all their unregarded surfaces, the rough furrow of the fast-driven chisel, as distinctly as the edge of a common paving-stone.

180. Let me suggest to you, in conclusion, one most interesting point of mental expression in these necessary aspects of finely executed sculpture. I have already again and again pressed on your attention the beginning of the arts of men in the make and use of the ploughshare. Read more carefully—you might indeed do well to learn at once by heart,—the twenty-seven lines of the Fourth Pythian, which describe the ploughing of Jason. There is nothing grander extant in human fancy, nor set down in human words: but this great mythical expression of the conquest of the earth-clay, and brute-force, by vital human energy, will become yet more interesting to you when you reflect what enchantment has been cut, on whiter clay, by the tracing of finer furrows;—what the delicate and consummate arts of man have done by the ploughing of marble, and granite, and iron. You will learn daily more and more, as you advance in actual practice, how the primary manual art of engraving, in the steadiness, clearness, and irrevocableness of it, is the best art-discipline that can be given either to mind or hand;[134 - That it was also, in, some cases, the earliest that the Greeks gave, is proved by Lucian's account of his first lesson at his uncle's; the ενκοπευς, literally "in-cutter"—being the first tool put into his hand, and an earthenware tablet to cut upon, which the boy pressing too hard, presently breaks;—gets beaten—goes home crying, and becomes, after his dream above quoted, a philosopher instead of a sculptor.] you will recognize one law of right, pronouncing itself in the well-resolved work of every age; you will see the firmly traced and irrevocable incision determining not only the forms, but, in great part, the moral temper, of all vitally progressive art; you will trace the same principle and power in the furrows which the oblique sun shows on the granite of his own Egyptian city,—in the white scratch of the stylus through the colour on a Greek vase—in the first delineation, on the wet wall, of the groups of an Italian fresco; in the unerring and unalterable touch of the great engraver of Nüremberg,—and in the deep driven and deep bitten ravines of metal by which Turner closed, in embossed limits, the shadows of the Liber Studiorum.

Learn, therefore, in its full extent, the force of the great Greek word, χαρασσω;—and, give me pardon—if you think pardon needed, that I ask you also to learn the full meaning of the English word derived from it. Here, at the Ford of the Oxen of Jason, are other furrows to be driven than these in the marble of Pentelicus. The fruitfullest, or the fatallest of all ploughing is that by the thoughts of your youth, on the white field of its imagination. For by these, either down to the disturbed spirit, "κεκοπται και χαρασσεται πεδον;" or around the quiet spirit, and on all the laws of conduct that hold it, as a fair vase its frankincense, are ordained the pure colours, and engraved the just Characters, of Æonian life.

LECTURE VI

THE SCHOOL OF ATHENS

December, 1870

181. It can scarcely be needful for me to tell even the younger members of my present audience, that the conditions necessary for the production of a perfect school of sculpture have only twice been met in the history of the world, and then for a short time; nor for short time only, but also in narrow districts, namely, in the valleys and islands of Ionian Greece, and in the strip of land deposited by the Arno, between the Apennine crests and the sea.

All other schools, except these two, led severally by Athens in the fifth century before Christ, and by Florence in the fifteenth of our own era, are imperfect; and the best of them are derivative: these two are consummate in themselves, and the origin of what is best in others.

182. And observe, these Athenian and Florentine schools are both of equal rank, as essentially original and independent. The Florentine, being subsequent to the Greek, borrowed much from it; but it would have existed just as strongly—and, perhaps, in some respects, more nobly—had it been the first, instead of the latter of the two. The task set to each of these mightiest of the nations was, indeed, practically the same, and as hard to the one as to the other. The Greeks found Phœnician and Etruscan art monstrous, and had to make them human. The Italians found Byzantine and Norman art monstrous, and had to make them human. The original power in the one case is easily traced; in the other it has partly to be unmasked, because the change at Florence was, in many points, suggested and stimulated by the former school. But we mistake in supposing that Athens taught Florence the laws of design; she taught her, in reality, only the duty of truth.

183. You remember that I told you the highest art could do no more than rightly represent the human form. This is the simple test, then, of a perfect school,—that it has represented the human form, so that it is impossible to conceive of its being better done. And that, I repeat, has been accomplished twice only: once in Athens, once in Florence. And so narrow is the excellence even of these two exclusive schools, that it cannot be said of either of them that they represented the entire human form. The Greeks perfectly drew, and perfectly moulded the body and limbs; but there is, so far as I am aware, no instance of their representing the face as well as any great Italian. On the other hand, the Italian painted and carved the face insuperably; but I believe there is no instance of his having perfectly represented the body, which, by command of his religion, it became his pride to despise, and his safety to mortify.
