a celebrated Greek architect, who flourished in the fifth century B.C. He was the contemporary of Pericles, under whose administration he planned, and built the famous Parthenon at Athens. This temple, which was of the Doric order, was completed in B.C. 438, seven years before the breaking out of the Peloponnesian War. To Ictinus was due the hardly less famous and splendid temple of Apollo Epicurus, at Phigalia in Arcadia, and the shrine of Eleusis, in which the mystic rites of Ceres were celebrated. None of the details of Ictinus' personal history are known.
