§ XLI. Consider, then, first, what marble seems to have been made for. Over the greater part of the surface of the world, we find that a rock has been providentially distributed, in a manner particularly pointing it out as intended for the service of man. Not altogether a common rock, it is yet rare enough to command a certain degree of interest and attention wherever it is found; but not so rare as to preclude its use for any purpose to which it is fitted. It is exactly of the consistence which is best adapted for sculpture: that is to say, neither hard nor brittle, nor flaky nor splintery, but uniform, and delicately, yet not ignobly, soft,--exactly soft enough to allow the sculptor to work it without force, and trace on it the finest lines of finished form; and yet so hard as never to betray the touch or moulder away beneath the steel; and so admirably crystallized, and of such permanent elements, that no rains dissolve it, no time changes it, no atmosphere decomposes it: once shaped, it is shaped for ever, unless subjected to actual violence or attrition. This rock, then, is prepared by Nature for the sculptor and architect, just as paper is prepared by the manufacturer for the artist, with as great--nay, with greater--care, and more perfect adaptation of the material to the requirements. And of this marble paper, some is white and some colored; but more is colored than white, because the white is evidently meant for sculpture, and the colored for the covering of large surfaces. § XLII. Now, if we would take Nature at her word, and use this precious paper which she has taken so much care to provide for us (it is a long process, the making of that paper; the pulp of it needing the subtlest possible solution, and the pressing of it--for it is all hot-pressed--having to be done under the saw, or under something at least as heavy); if, I say, we use it as Nature would have us, consider what advantages would follow. The colors of marble are mingled for us just as if on a prepared palette. They are of all shades and hues (except bad ones), some being united and even, some broken, mixed, and interrupted, in order to supply, as far as possible, the want of the painter's power of breaking and mingling the color with the brush. But there is more in the colors than this delicacy of adaptation. There is history in them. By the manner in which they are arranged in every piece of marble, they record the means by which that marble has been produced, and the successive changes through which it has passed. And in all their veins and zones, and flame-like stainings, or broken and disconnected lines, they write various legends, never untrue, of the former political state of the mountain kingdom to which they belonged, of its infirmities and fortitudes, convulsions and consolidations, from the beginning of time.
