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.

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.
