Son of the Cursed House
Orestes was born into the most cursed family in Greek mythology — the House of Atreus, descended from Tantalus. His father was Agamemnon, the king who led the Greeks at Troy. His mother was Clytemnestra. His sister was Electra.
When Agamemnon returned from the Trojan War, Clytemnestra and her lover Aegisthus murdered him. Young Orestes was spirited away to safety, but he grew up knowing that duty demanded he avenge his father — even though that meant killing his own mother.
The Impossible Choice
Orestes faced a dilemma with no good answer. Apollo commanded him to avenge his father by killing Clytemnestra. But the ancient law of blood guilt — enforced by the Furies (Erinyes) — demanded that anyone who killed their own mother be hunted to madness and death.
He would be punished for acting. He would be punished for not acting. This is the tragic bind that makes the Oresteia one of the greatest works of Western literature.
The Matricide
Orestes returned to Argos with his cousin Pylades, entered the palace in disguise, and killed Aegisthus first. Then he confronted Clytemnestra. She bared her breast and begged him to spare the mother who nursed him. In Aeschylus's version, Orestes hesitated — then looked to Pylades, who reminded him of Apollo's command. He killed her.
Immediately, the Furies appeared — ancient goddesses of vengeance, older than the Olympians, with blood dripping from their eyes and serpents writhing in their hair. They chased Orestes across Greece, driving him to the edge of madness.
Trial at Athens
Orestes fled to Athens, where Athena established the first murder trial in history — the Areopagus court. Apollo served as Orestes' defense attorney. The Furies prosecuted. Athena presided as judge.
The jury of Athenian citizens voted — and the result was a tie. Athena cast the deciding vote in Orestes' favor, acquitting him. She then persuaded the Furies to accept a new role as the Eumenides ('Kindly Ones'), protectors of Athens, transforming the cycle of vengeance into a system of justice.
This trial represents one of the foundational myths of democratic law — the moment violence gave way to civic order.
