In architecture, one of the orders of ancient Greece and also found in cities of western Turkey and the islands of the eastern Aegean. The elegantly designed column has a capital formed by two sets of volutes, which looked like a pair of formalized ram's horns. In between the volutes is an echinus decorated with an egg-and-dart pattern. The entablature allowed for a continuous frieze, which could be decorated in relief. The diameter-to-height ratio of between one-to-eight and one-to-ten. In classical architecture, the Ionic order emerged after Doric, perhaps from about 570 BC. Unlike the Doric, the Ionic capital has four distinct sides, only two of which are intended to be conspicuous.
