Letters 65.3

All art is but imitation of nature; therefore, let me apply these statements of general principles to the things which have to be made by man. A statue, for example, has afforded matter which was to undergo treatment at the hands of the artist, and has had an artist who was to give form to the matter. Hence, in the case of the statue, the material was bronze, the cause was the workman. And so it goes with all things,—they consist of that which is made, and of the maker.
