Ixīon, onis, m., = Ἰξίων, the son of Phlegyas (acc. to others, of Antion or of Jupiter), king of the Lapithae in Thessaly, and father of Pirithous. He murdered his father-in-law, to avoid paying the nuptial presents; and as no one would absolve him after such a deed, Jupiter took him into heaven and there purified him. When, notwithstanding this, he made an attempt on the chastity of Juno, Jupiter substituted for her an image of cloud, with which he begat the Centaurs; but having boasted of his imaginary criminal success with Juno, Jupiter hurled him into Tartarus, where he was bound fast to an ever-revolving wheel, Ov. M. 4, 465; 10, 42; Verg. A. 6, 601: Ixione natus, i. e. Pirithous, Ov. M. 12, 210: Ixione nati, the Centaurs. id. ib. 12, 504.
