The simplicity is very marked. There are three principal figures. I believe, if there were nothing else but these, the balance of the composition would be complete, and certainly the allegory would be explained. But balance is not necessarily harmony. In a school debate, for instance, ten of you on the right of the room may say “aye,” and ten on the left may say “no,” to a subject which is being discussed between you. There is a balance--ten on one side, opposed to ten on the other.
