The Ionic order originated in the mid-6th century BC in Ionia (broadly equivalent to modern day İzmir Province), as well as the southwestern coastland and islands of Asia Minor settled by Ionians, where Ionic Greek was spoken. The Ionic order column was being practiced in mainland Greece in the 5th century BC. It was most popular in the Archaic Period (750-480 BC) in Ionia. The first of the great Ionic temples was the Temple of Hera on Samos, built about 570-560 BC by the architect Rhoikos. It stood for only a decade before it was leveled by an earthquake. A longer-lasting 6th century Ionic temple was the Temple of Artemis at Ephesus, one of the Seven Wonders of the Ancient World. The Parthenon, although it conforms mainly to the Doric order, also has some Ionic elements. A more purely Ionic mode to be seen on the Athenian Acropolis is exemplified in the Erechtheum.
