 Every statue on the west pediment has a fully completed back, which would have been impossible to see when the sculpture was on the temple; this indicates that the sculptors put great effort into accurately portraying the human body.The only piece of sculpture from the Parthenon known to be from the hand of Phidias was the statue of Athena housed in the "naos".This massive chryselephantine sculpture is now lost and known only from copies, vase painting, gems, literary descriptions and coins.
