 Clytemnestra

Clytemnestra (; , "Klytaimnḗstra", ), in Greek mythology, was the wife of Agamemnon, king of Mycenae, and the sister of Helen of Troy.In Aeschylus' "Oresteia", she murders Agamemnon – said by Euripides to be her second husband – and the Trojan princess Cassandra, whom Agamemnon had taken as a war prize following the sack of Troy; however, in Homer's "Odyssey", her role in Agamemnon's death is unclear and her character is significantly more subdued.
