CLITERMYSTRA. Clytemnestra was the wife of Agamemnon, high king of Mycenae. While her husband was fighting the Trojan War, Clytemnestra took his brother Aegistus as her lover. When her husband returned with Cassandra as his concubine, Clytemnestra and Aegistus murdered them both. Jerome cites her as an evil wife, Epistola adversus Jovinianum (Letter Against Jovinian) I.48 (PL 23: 280).
