Megăcles in Harpers Dictionary of Classical Antiquities

1. A name borne by several of the Athenian family of the Alcmaeonidae. The most important of these was the Megacles who put to death Cylon and his adherents after they had taken refuge at the altar of Athené, B.C. 612. (See Cylon.) 2. Son of Alcmaeon , son-inlaw of Clisthenes, leader of the Alcmaeonidae in the time of Solon. At first he was opposed to Pisistratus, and expelled him from Athens; but afterwards he became reconciled to him, gave him his daughter Coesyra in marriage, and assisted in his restoration to Athens. Pisistratus not having treated his wife in a proper manner, Megacles resented the affront, and again drove the former out of Athens; with the aid of large sums from the Thebans and other States, Pisistratus again raised an army, defeated his opponents, and drove Megacles and the partisans of the Alcmaeonidae into exile. 3. A Syracusan, brother of Dion, and brother-in-law of the elder Dionysius. He accompanied Dion in his flight from Syracuse, B.C. 358, and afterwards returned with him to Sicily.
