 This reference, as well as a structure listed in an inscription, has been interpreted as evidence that the Opisthodomus of the Old Temple remained in place through the fifth century.Xenophon states that the Old Temple of Athena burned down in 406/405 BC, but this might also refer to the Erechtheion, which had taken over the functions of the Old Temple and housed the Xoanon.From the 4th century BC onwards, there are no possible references to the Old Temple; Pausanias was not aware of its existence.
