After Athena announces his acquittal in the trial of the Eumenides, Orestes offers thanks to the three gods who have driven him from the house into the city to restore him once again to his house — Pallas, Loxias, and the Third Savior who accomplishes all things, Zeus Sōtēr (757-760). In the plot of the Oresteia, this triad has made Orestes the third savior for whom the Chorus of the Choephoroi pray (1073); he comes in the third generation, after Atreus and Agamemnon, to save his line from the extinction threatened by the atē working its way through the generational cycles of the House of Atreus. His trial, which establishes in the polis the precedent of Ixion (cf. 441, 717-718), brings it an unbeatable grip of salvation and victory against its opponents (776-777). The evolution he thus effects in the human ethical order is an unwitting imitation, with Orestes as a human counterpart to Zeus, of the evolution in the divine ethical order effected by the young Olympian gods in the Prometheia, for only in the third generation, after Ouranos and Kronos, does Zeus halt the lawless cycle of divine usurpation. Zeus proves triaktēr, victor in the third bout, in the struggle for control of the kosmos (cf. Ag. 168-172); likewise, Orestes overcomes the atē which Elektra describes as atriaktos (Cho. 339), and, having offered Aegisthus as a third libation (Cho. 577-578), he proves triaktēr in his agōn against the Erinyes, although they claim to have tripped him in the first of three bouts (Eum. 589). Human history is an imitation of divine history, accomplished under Zeus' command by the Olympian gods, who seek to bring man's ethical order into line with the new order of the kosmos; only by thus reconciling the Chthonic gods to the new order can the Olympians establish the harmonia necessary if Zeus' regime is to stop permanently the cycle of crime and counter-crime.
