 Caryatids, draped female figures used as supporting members to carry the entablature, were a feature of the Ionic order, occurring at several buildings including the Siphnian Treasury at Delphi in 525 BC and at the Erechtheion, about 410 BC.The Corinthian order does not have its origin in wooden architecture.It grew directly out of the Ionic in the mid 5th century BC, and was initially of much the same style and proportion, but distinguished by its more ornate capitals.
