Scion of the Pelopid house (son of the scion Atreus by the mortal Aerope). King of Mycenae and supreme commander of the Greek coalition at Troy — Homer's 'lord of men.' Sacrificed his daughter Iphigenia at Aulis for sailing wind; his quarrel with Achilles over Briseis drives the Iliad. Murdered at his homecoming by his wife Clytemnestra and her lover Aegisthus — snared in a robe and axed in the bath in Aeschylus — the killing that the Odyssey contrasts with Odysseus's safe return and that the Oresteia builds upon. Brother of Menelaus and Anaxibia; father of Iphigenia, Electra, Chrysothemis, and Orestes.
