There is at the back of every artist’s mind something like a pattern or a type of architecture. The original quality in any man of imagination is imagery. It is a thing like the landscape of his dreams; the sort of world he would like to make or in which he would wish to wander; the strange flora and fauna of his own secret planet; the sort of thing he likes to think about. This general atmosphere, and pattern or structure of growth, governs all his creations, however varied.
