Clytemnestra

Clytemnestra was the wife of Agamemnon, the king of of Mycenae and leader of the Greek forces in the Trojan War. When the winds prevented the Greek ships from sailing. Agamemnon was told that the winds would return if he sacrificed his daughter Iphigeneia. Knowing that Clytemnestra never would permit this, he asked her to send Iphigeneia because he wanted to marry her to Achilles. When Iphigeneia arrived, she was sacrificed, which caused a lot of griev to her mother.

During the siege of Troja the horny Agamemnon quarrelled with Achilles for the posession of the female booty they made in the war, and nearly ruined the Greek cause by his greed. After the war he returned with Cassandra princess of Troy as his concubine.

In the meantime Clytemnestra had began a love affair with Aegisthus, her husband's cousin. When Agamemnon arrived in Mycenae she waited until he was taking a bath and then she slaughtered him. Liberating herself and Greece of an egoistic horny old king.

This interesting interpretation is by the British painter John Collier (1850–1934), and its called "After the murder" (1882). It depicts Clytemnestra bloody and with an hevy axe like a butcher, but she is looking proud and content.
