in Greek legend, son either of the god Ares or of Phlegyas, king of the Lapiths in Thessaly. He murdered his father-in-law and could find no one to purify him until Zeus did so and admitted him as a guest to Olympus. Ixion abused his pardon by trying to seduce Zeus's wife, Hera. Zeus substituted for her a cloud, by which Ixion became the father of Centaurus, who fathered the Centaurs by the mares of Mount Pelion. Zeus, to punish him, bound him on a fiery wheel, which rolled unceasingly through the air or, according to the more common tradition, in the underworld.
