§47 Because beauty accompanied with grace is the principal object of sculpture, it loves nakedness, and allows clothing only so far as it does not conceal the form. It makes use of drapery, not as a covering, but as a means of exhibiting the form, a method of exposition that gives much exercise to the understanding, for it can only arrive at a perception of the cause, the form of the body, through the only directly given effect, the drapery. Thus to a certain extent drapery is in sculpture what fore-shortening is in painting. Both are suggestions, yet not symbolical, but such that, if they are successful, they force the understanding directly to perceive what is suggested, just as if it were actually given.
