Greek Ionic Order
The Ionic order column originated in the mid-6th century BC in Ionia. The Ionic order column was being practiced in mainland Greece in the 5th century BC. The first of the great Ionic temples was the Temple of Hera on Samos, built about 570 BC–560 BC by the architect Rhoikos. It stood for only a decade before it was leveled by an earthquake. It was in the great sanctuary of the goddess: it could scarcely have been in a more prominent location for its brief lifetime. A longer-lasting 6th century Ionic temple was the Temple of Artemis at Ephesus, one of the Seven Wonders of the Ancient World.
