3. A son of Creon of Thebes, perished, according to some accounts, by the sphinx. (Apollod. 3.5.8; Schol. ad Eurip. Phoen. 1760.) But, according to other traditions, he survived the war of the Seven against Thebes, and he is said to have been in love with Antigone, and to have made away with himself on hearing that she was condemned by his father to be entombed alive. (Soph. Antig. 627, &c.; Eur. Phoen. 757, 1587; Hyg. Fab. 72.) In the Iliad (4.394) Macon is called a son of Haemon.
