The Crown of Wild Olive Part 26

_December, 1870._

143. On previous occasions of addressing you, I have endeavoured to show you, first, how sculpture is distinguished from other arts; then its proper subjects, then its proper method in the realization of these subjects. To-day, we must, in the fourth place, consider the means at its command for the accomplishment of these ends; the nature of its materials; and the mechanical or other difficulties of their treatment.

And however doubtful we may have remained, as to the justice of Greek ideals, or propriety of Greek methods of representing them, we may be certain that the example of the Greeks will be instructive in all practical matters relating to this great art, peculiarly their own. I think even the evidence I have already laid before you is enough to convince you, that it was by rightness and reality, not by idealism or delightfulness only, that their minds were finally guided; and I am sure that, before closing the present course, I shall be able so far to complete that evidence, as to prove to you that the commonly received notions of cla.s.sic art are, not only unfounded, but even in many respects, directly contrary to the truth. You are constantly told that Greece idealized whatever she contemplated. She did the exact contrary: she realized and verified it. You are constantly told she sought only the beautiful. She sought, indeed, with all her heart; but she found, because she never doubted that the search was to be consistent with propriety and common sense. And the first thing you will always discern in Greek work is the first which you _ought_ to discern in all work; namely, that the object of it has been rational, and has been obtained by simple and unostentatious means.

144. "That the object of the work has been rational!" Consider how much that implies. That it should be by all means seen to have been determined upon, and carried through, with sense and discretion; these being gifts of intellect far more precious than any knowledge of mathematics, or of the mechanical resources of art. Therefore, also, that it should be a modest and temperate work, a structure fitted to the actual state of men; proportioned to their actual size, as animals,--to their average strength,--to their true necessities,--and to the degree of easy command they have over the forces and substances of nature.

145. You see how much this law excludes! All that is fondly magnificent, insolently ambitious, or vainly difficult. There is, indeed, such a thing as Magnanimity in design, but never unless it be joined also with modesty and _Equ_animity. Nothing extravagant, monstrous, strained, or singular, can be structurally beautiful. No towers of Babel envious of the skies; no pyramids in mimicry of the mountains of the earth; no streets that are a weariness to traverse, nor temples that make pigmies of the wors.h.i.+ppers.

It is one of the primal merits and decencies of Greek work that it was, on the whole, singularly small in scale, and wholly within reach of sight, to its finest details. And, indeed, the best buildings that I know are thus modest; and some of the best are minute jewel cases for sweet sculpture. The Parthenon would hardly attract notice, if it were set by the Charing Cross Railway Station: the Church of the Miracoli, at Venice, the Chapel of the Rose, at Lucca, and the Chapel of the Thorn, at Pisa, would not, I suppose, all three together, fill the tenth part, cube, of a transept of the Crystal Palace. And they are better so.

146. In the chapter on Power in the "Seven Lamps of Architecture," I have stated what seems, at first, the reverse of what I am saying now; namely, that it is better to have one grand building than any number of mean ones. And that is true, but you cannot command grandeur by size till you can command grace in minuteness; and least of all, remember, will you so command it to-day, when magnitude has become the chief exponent of folly and misery, co-ordinate in the fraternal enormities of the Factory and Poorhouse,--the Barracks and Hospital. And the final law in this matter is, that if you require edifices only for the grace and health of mankind, and build them without pretence and without chicanery, they will be sublime on a modest scale, and lovely with little decoration.

147. From these principles of simplicity and temperance, two very severely fixed laws of construction follow; namely, first, that our structure, to be beautiful, must be produced with tools of men; and secondly, that it must be composed of natural substances. First, I say, produced with tools of men. All fine art requires the application of the whole strength and subtlety of the body, so that such art is not possible to any sickly person, but involves the action and force of a strong man's arm from the shoulder, as well as the delicatest touch of his finger: and it is the evidence that this full and fine strength has been spent on it which makes the art executively n.o.ble; so that no instrument must be used, habitually, which is either too heavy to be delicately restrained, or too small and weak to transmit a vigorous impulse; much less any mechanical aid, such as would render the sensibility of the fingers ineffectual.[126]

148. Of course, any kind of work in gla.s.s, or in metal, on a large scale, involves some painful endurance of heat; and working in clay, some habitual endurance of cold; but the point beyond which the effort must not be carried is marked by loss of power of manipulation. As long as the eyes and fingers have complete command of the material (as a gla.s.s blower has, for instance, in doing fine ornamental work)--the law is not violated; but all our great engine and furnace work, in gun-making and the like, is degrading to the intellect; and no nation can long persist in it without losing many of its human faculties. Nay, even the use of machinery, other than the common rope and pully, for the lifting of weights, is degrading to architecture; the invention of expedients for the raising of enormous stones has always been a characteristic of partly savage or corrupted races. A block of marble not larger than a cart with a couple of oxen could carry, and a cross-beam, with a couple of pulleys, raise, is as large as should generally be used in any building. The employment of large ma.s.ses is sure to lead to vulgar exhibitions of geometrical arrangement,[127] and to draw away the attention from the sculpture. In general, rocks naturally break into such pieces as the human beings that have to build with them can easily lift, and no larger should be sought for.

149. In this respect, and in many other subtle ways, the law that the work is to be with tools of men is connected with the farther condition of its modesty, that it is to be wrought in substance provided by Nature, and to have a faithful respect to all the essential qualities of such substance.

And here I must ask your attention to the idea, and, more than idea,--the fact, involved in that infinitely misused term, "Providentia," when applied to the Divine Power. In its truest sense and scholarly use, it is a human virtue, [Greek: Prometheia]; the personal type of it is in Prometheus, and all the first power of [Greek: techne], is from him, as compared to the weakness of days when men without foresight "[Greek: ephyron eike panta]." But, so far as we use the word "Providence" as an attribute of the Maker and Giver of all things, it does not mean that in a s.h.i.+pwreck He takes care of the pa.s.sengers who are to be saved and takes none of those who are to be drowned; but it _does_ mean that every race of creatures is born into the world under circ.u.mstances of approximate adaptation to its necessities; and, beyond all others, the ingenious and observant race of man is surrounded with elements naturally good for his food, pleasant to his sight, and suitable for the subjects of his ingenuity;--the stone, metal, and clay of the earth he walks upon lending themselves at once to his hand, for all manner of workmans.h.i.+p.

150. Thus, his truest respect for the law of the entire creation is shown by his making the most of what he can get most easily; and there is no virtue of art, nor application of common sense, more sacredly necessary than this respect to the beauty of natural substance, and the ease of local use; neither are there any other precepts of construction so vital as these--that you show all the strength of your material, tempt none of its weaknesses, and do with it only what can be simply and permanently done.

151. Thus, all good building will be with rocks, or pebbles, or burnt clay, but with no artificial compound; all good painting, with common oils and pigments on common canvas, paper, plaster, or wood,--admitting, sometimes for precious work, precious things, but all applied in a simple and visible way. The highest imitative art should not, indeed, at first sight, call attention to the means of it; but even that, at length, should do so distinctly, and provoke the observer to take pleasure in seeing how completely the workman is master of the particular material he has used, and how beautiful and desirable a substance it was, for work of that kind. In oil painting its unctious quality is to be delighted in; in fresco, its chalky quality; in gla.s.s, its transparency; in wood, its grain; in marble, its softness; in porphyry, its hardness; in iron, its toughness. In a flint country, one should feel the delightfulness of having flints to pick up, and fasten together into rugged walls. In a marble country one should be always more and more astonished at the exquisite colour and structure of marble; in a slate country one should feel as if every rock cleft itself only for the sake of being built with conveniently.

[Ill.u.s.tration: PLATE X.--MARBLE MASONRY IN THE DUOMO OF VERONA.]

152. Now, for sculpture, there are, briefly, two materials--Clay, and Stone; for gla.s.s is only a clay that gets clear and brittle as it cools, and metal a clay that gets opaque and tough as it cools. Indeed, the true use of gold in this world is only as a very pretty and very ductile clay, which you can spread as flat as you like, spin as fine as you like, and which will neither crack, nor tarnish.

All the arts of sculpture in clay may be summed up under the word "Plastic," and all of those in stone, under the word "Glyptic."

153. Sculpture in clay will accordingly include all cast brick-work, pottery, and tile-work[128]--a somewhat important branch of human skill.

Next to the potter's work, you have all the arts in porcelain, gla.s.s, enamel, and metal; everything, that is to say, playful and familiar in design, much of what is most felicitously inventive, and, in bronze or gold, most precious and permanent.

154. Sculpture in stone, whether granite, gem, or marble, while we accurately use the general term "glyptic" for it, may be thought of with, perhaps, the most clear force under the English word "engraving."

For, from the mere angular incision which the Greek consecrated in the triglyphs of his greatest order of architecture, grow forth all the arts of bas-relief, and methods of localized groups of sculpture connected with each other and with architecture: as, in another direction, the arts of engraving and wood-cutting themselves.

155. Over all this vast field of human skill the laws which I have enunciated to you rule with inevitable authority, embracing the greatest, and consenting to the humblest, exertion; strong to repress the ambition of nations, if fantastic and vain, but gentle to approve the efforts of children, made in accordance with the visible intention of the Maker of all flesh, and the Giver of all Intelligence. These laws, therefore, I now repeat, and beg of you to observe them as irrefragable.

1. That the work is to be with tools of men.

2. That it is to be in natural materials.

3. That it is to exhibit the virtues of those materials, and aim at no quality inconsistent with them.

4. That its temper is to be quiet and gentle, in harmony with common needs, and in consent to common intelligence.

We will now observe the bearing of these laws on the elementary conditions of the art at present under discussion.

156. There is, first, work in baked clay, which contracts as it dries, and is very easily frangible. Then you must put no work into it requiring niceness in dimension, nor any so elaborate that it would be a great loss if it were broken, but as the clay yields at once to the hand, and the sculptor can do anything with it he likes, it is a material for him to sketch with and play with,--to record his fancies in, before they escape him--and to express roughly, for people who can enjoy such sketches, what he has not time to complete in marble. The clay, being ductile, lends itself to all softness of line; being easily frangible, it would be ridiculous to give it sharp edges, so that a blunt and ma.s.sive rendering of graceful gesture will be its natural function; but as it can be pinched, or pulled, or thrust in a moment into projection which it would take hours of chiselling to get in stone, it will also properly be used for all fantastic and grotesque form, not involving sharp edges. Therefore, what is true of chalk and charcoal, for painters, is equally true of clay, for sculptors; they are all most precious materials for true masters, but tempt the false ones into fatal license; and to judge rightly of terra-cotta work is a far higher reach of skill in sculpture-criticism than to distinguish the merits of a finished statue.

157. We have, secondly, work in bronze, iron, gold, and other metals; in which the laws of structure are still more definite.

All kinds of twisted and wreathen work on every scale become delightful when wrought in ductile or tenacious metal, but metal which is to be _hammered_ into form separates itself into two great divisions--solid, and flat.

[Ill.u.s.tration: PLATE XI.--THE FIRST ELEMENTS OF SCULPTURE.

Incised Outline and Opened s.p.a.ce.]

(A.) In solid metal work, _i. e._, metal cast thick enough to resist bending, whether it be hollow or not, violent and various projection may be admitted, which would be offensive in marble; but no sharp edges, because it is difficult to produce them with the hammer. But since the permanence of the material justifies exquisiteness of workmans.h.i.+p, whatever delicate ornamentation can be wrought with rounded surfaces may be advisedly introduced; and since the colour of bronze or any other metal is not so pleasantly representative of flesh as that of marble, a wise sculptor will depend less on flesh contour, and more on picturesque accessories, which, though they would be vulgar if attempted in stone, are rightly entertaining in bronze or silver. Verrochio's statue of Colleone at Venice, Cellini's Perseus at Florence, and Ghiberti's gates at Florence, are models of bronze treatment.

(B.) When metal is beaten thin, it becomes what is technically called "plate," (the _flattened_ thing) and may be treated advisably in two ways; one, by beating it out into bosses, the other by cutting it into strips and ramifications. The vast schools of goldsmith's work and of iron decoration, founded on these two principles, have had the most powerful influences over general taste in all ages and countries. One of the simplest and most interesting elementary examples of the treatment of flat metal by cutting is the common branched iron bar, Fig. 8, used to close small apertures in countries possessing any good primitive style of iron-work, formed by alternate cuts on its sides, and the bending down of the several portions. The ordinary domestic window balcony of Verona is formed by mere ribands of iron, bent into curves as studiously refined as those of a Greek vase, and decorated merely by their own terminations in spiral volutes.

[Ill.u.s.tration: FIG. 8.]

All cast work in metal, unfinished by hand, is inadmissible in any school of living art, since it cannot possess the perfection of form due to a permanent substance; and the continual sight of it is destructive of the faculty of taste: but metal stamped with precision, as in coins, is to sculpture what engraving is to painting.

158. Thirdly. Stone-sculpture divides itself into three schools: one in very hard material; one in very soft, and one in that of centrally useful consistence.

A. The virtue of work in hard material is the expression of form in shallow relief, or in broad contours; deep cutting in hard material is inadmissible, and the art, at once pompous and trivial, of gem engraving, has been in the last degree destructive of the honour and service of sculpture.

B. The virtue of work in soft material is deep cutting, with studiously graceful disposition of the ma.s.ses of light and shade. The greater number of flamboyant churches of France are cut out of an adhesive chalk; and the fantasy of their latest decoration was, in great part, induced by the facility of obtaining contrast of black s.p.a.ce, undercut, with white tracery easily left in sweeping and interwoven rods--the lavish use of wood in domestic architecture materially increasing the habit of delight in branched complexity of line. These points, however, I must reserve for ill.u.s.tration in my lectures on architecture. To-day, I shall limit myself to the ill.u.s.tration of elementary sculptural structure in the best material;--that is to say, in crystalline marble, neither soft enough to encourage the caprice of the workman, nor hard enough to resist his will.

159. C. By the true "Providence" of Nature, the rock which is thus submissive has been in some places stained with the fairest colours, and in others blanched into the fairest absence of colour, that can be found to give harmony to inlaying, or dignity to form. The possession by the Greeks of their [Greek: leukos lithos] was indeed the first circ.u.mstance regulating the development of their art; it enabled them at once to express their pa.s.sion for light by executing the faces, hands, and feet of their dark wooden statues in white marble, so that what we look upon only with pleasure for fineness of texture was to them an imitation of the luminous body of the deity s.h.i.+ning from behind its dark robes; and ivory afterwards is employed in their best statues for its yet more soft and flesh-like brightness, receptive also of the most delicate colour--(therefore to this day the favourite ground of miniature painters). In like manner, the existence of quarries of peach-coloured marble within twelve miles of Verona, and of white marble and green serpentine between Pisa and Genoa, defined the manner both of sculpture and architecture for all the Gothic buildings of Italy. No subtlety of education could have formed a high school of art without these materials.

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 draughtsmans.h.i.+p, 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 ma.s.ses 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] 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--peac.o.c.ks and kingfishers,--b.u.t.terflies and flowers, on grounds of gold, and the like, as they were in Byzantine work. I shall expect you, in right use of your aesthetic 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 s.p.a.ce 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 ma.s.s 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 s.p.a.ce 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 ma.s.ses of their building; but put their chief sculpture in the empty s.p.a.ces 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 n.o.blest rec.u.mbent 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 quant.i.ty of sculpture of all times and styles may be generally embraced under the notion of a ma.s.s 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.
