 Some studies of the Acropolis, including of the Parthenon and its façade, have conjectured that many of its proportions approximate the golden ratio.However, such theories have been discredited by more recent studies, which have shown that the proportions of the Parthenon do not match the golden proportion.The cella of the Parthenon housed the chryselephantine statue of Athena Parthenos sculpted by Phidias and dedicated in 439 or 438 BC.
