After the murder of Agamemnon, Klitaimnistra and Aigisthos marry Electra with a poor peasant so as to send her away from the palace. Orestis, the son of Agamemnon is exiled and after many years returns to his country obeying the exhortation of Apollo to revenge the death of his father and with his sister Electra organizes the plan of revenge. This murder causes the mental collapse of the heroes although the deus ex machina appearance of the Dioskouri gives solution to the drama. Euripides places the problem in a human context and presents the matricide as a family matter of Atreides. The curse of the family is not inspired by God but it emanates from their insatiable thirst for power.
