§ 41 The Small Sketch-Model in Wax or Clay
Sculptors, when they wish to work a figure in marble, are accustomed to make what is called a model for it in clay or wax or plaster; that is, a pattern, about a foot high, more or less, according as is found convenient, because they can exhibit in it the attitude and proportion of the figure that they wish to make, endeavouring to adapt themselves to the height and breadth of the stone quarried for their statue.
