XI. But it will be said that all this want of organisation and form might be affirmed of drapery also, and that this latter is a noble subject of sculpture. By no means. When was drapery a subject of sculpture by itself, except in the form of a handkerchief on urns in the seventeenth century and in some of the baser scenic Italian decorations? Drapery, as such, is always ignoble; it becomes a subject of interest only by the colors it bears, and the impressions which it receives from some foreign form or force. All noble draperies, either in painting or sculpture (color and texture being at present out of our consideration), have, so far as they are anything more than necessities, one of two great functions; they are the exponents of motion and of gravitation. They are the most valuable means of expressing past as well as present motion in the figure, and they are almost the only means of indicating to the eye the force of gravity which resists such motion. The Greeks used drapery in sculpture for the most part as an ugly necessity, but availed themselves of it gladly in all representation of action, exaggerating the arrangements of it which express lightness in the material, and follow gesture in the person. The Christian sculptors, caring little for the body, or disliking it, and depending exclusively on the countenance, received drapery at first contentedly as a veil, but soon perceived a capacity of expression in it which the Greek had not seen or had despised. The principal element of this expression was the entire removal of agitation from what was so pre-eminently capable of being agitated. It fell from their human forms plumb down, sweeping the ground heavily, and concealing the feet; while the Greek drapery was often blown away from the thigh. The thick and coarse stuffs of the monkish dresses, so absolutely opposed to the thin and gauzy web of antique material, suggested simplicity of division as well as weight of fall. There was no crushing nor subdividing them. And thus the drapery gradually came to represent the spirit of repose as it before had of motion, repose saintly and severe. The wind had no power upon the garment, as the passion none upon the soul; and the motion of the figure only bent into a softer line the stillness of the falling veil, followed by it like a slow cloud by drooping rain: only in links of lighter undulation it followed the dances of the angels.
