The Eumenides

Orestes, Apollo, and the Erinyes go before Athena and eleven other judges chosen by her from the Athenian citizenry at the Areopagus (Rock of Ares, a flat rocky hill by the Athenian agora where the homicide court of Athens later held its sessions), to decide whether Orestes's killing of his mother, Clytemnestra, makes him guilty of the crime of murder.
