The first sanctuary (temenos) antedated the Ionic immigration by many years, and dates to the Bronze Age. Callimachus, in his Hymn to Artemis, attributed it to the Amazons. In the 7th century BC, the old temple was destroyed by a flood. Its reconstruction began around 550 BC, under the Cretan architect Chersiphron and his son Metagenes, at the expense of Croesus of Lydia: the project took 10 years to complete, only to be destroyed in an act of arson by Herostratus. It was later rebuilt.
