Sculpture might be the most severe test in art. Michelangelo could not go back. Once he cut the stone, the shape was there. The vision has to be clear and complete in order for Michelangelo to bring the sculptured piece out of the stone. In every other art you are adding on, in sculpture you are detracting. And if you keep taking away the stone and changing your mind you end up with no stone.
