Classical period the change in sculpture was embodied by one word: controposto. The most significant change in sculpture to that date, controposto was the counterbalance, or s- curve of the body. One foot came forward and the weight distribution became more naturalistic. Besides conroposto, the other characteristics of Classical sculpture were: head turned on different plain from body (aloof, representing reason controlled) and less formal hair treatment. Archaic was carving stone into body, while Classical was carving a body out of stone. The Canon, by Polyclitus, is the archetype of classical sculpture. The goal of classical sculpture was to portray a perfect balance and harmony through art. This mirrored Greek philosophy.
