A sort of canon of cosmic architecture. And in the architecture of human hands it makes more for the beauty of a frieze to have a procession of various figures, like the procession of Athenian knights in the frieze of the Parthenon, than to have one cast reproduced all round, suggestive of so much a foot. It makes for the beauty, and adds to the expense, but with the Creator there is no question of expense. But is not every human character the presentation of a distinct history, and every human face and form expressive of an individuality all its own?
