Clytemnestra

Clytemnestra or Clytaemnestra (pronounced /ˌklaɪtəmˈniːstrə/; Greek: Κλυταιμνήστρα, ), in ancient Greek legend, was the wife of Agamemnon, king of the Ancient Greek kingdom of Mycenae or Argos. In the Oresteia by Aeschylus, she was a femme fatale who murdered her husband, Agamemnon – said by Euripides to be her second husband – and the Trojan princess Cassandra, whom he had taken as 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.
