According to legend, the city of Mycenae was founded by Perseus, the slayer of Medusa the Gorgon, before it fell into the bloodied hands of the House of Atreus. Atreus, in an act of vengeance for his wife’s seduction by his brother Thyestes, murdered Thyestes’ sons, and fed them to their father. Not surprisingly, this incurred the wrath of the gods: Thyestes’ daughter, Pelopia, subsequently bore her father a son, Aegisthus, who later murdered Atreus and restored Thyestes to the throne.
The next generation saw the gods’ curse fall upon Atreus’ son Agamemnon. On his return to Mycenae after commanding the Greek forces in the Trojan War – a role in which he had earlier consented to the sacrifice of his own daughter, Iphigeneia – he was killed in his bath by his wife Klytemnestra and her lover, Aegisthus, who had also killed his father. The tragic cycle was completed by Agamemnon’s son, Orestes, who, egged on by his sister Elektra, took revenge by murdering his mother, Klytemnestra, and was pursued by the Furies until Athena finally lifted the curse on the dynasty.
