Other orders

Most Greek temple are classed into the Ionic or Doric order, there are, however, some exceptions. Aeolic order, developed in Aeolian regions, though some temples in Sicily have this style, has almost same structure as Ionic, except for the capital, on which a palmette emerges from between two volutes.

Corinthian order, which has also similar features as Ionic, was invented in the fifth century and became the most favoured order in Roman Period. The capital has a long echinos with two or three leveled leaves of Acansas emerged and some coiled tendrils supporting Abacus. In the classical period, this order was used only for a part of columns such as the temple of Apollon at Bassai or the temple of Athena at Tegea. It was popularized in Roman era and the temple of Zeus at Athens is largest one in Greek mainland.
