The sacred site at Ephesus was far older than the Artemision (Temple of Artemis). Pausanias understood the shrine of Artemis there to be very ancient. He states with certainty that it antedated the Ionic Immigration by many years, being older even than the oracular shrine of Apollo at Didyma. He said that the pre-Ionic inhabitants of the city were Leleges and Lydians. Callimachus, in his Hymn to Artemis, attributed the origin of the temenos at Ephesus to the Amazons, whose worship he imagines already centered upon an image (bretas).
