The Oresteian Trilogy ( Aeschylus)

After the Fall of Troy, King Agamemnon returns to Argos, a victor in war. Agamemnon depicts the hero's discovery that his family has been destroyed by his wife's infidelity and ends with his death at her callous hand. Clytemnestra's crime is repaid in The Choephori when her outraged son Orestes kills both her and her lover.
