Oresteia instance of theatrical trilogy
The Oresteia (Ancient Greek: Ὀρέστεια) is a trilogy of Greek tragedies written by Aeschylus in the 5th century BCE, concerning the murder of Agamemnon by Clytemnestra, the murder of Clytemnestra by Orestes, the trial of Orestes, the end of the curse on the House of Atreus and the pacification of the Furies (also called Erinyes or Eumenides).
The trilogy—consisting of Agamemnon (Ἀγαμέμνων), The Libation Bearers (Χοηφόροι), and The Eumenides (Εὐμενίδες)—also shows how the Greek gods interacted with the characters and influenced their decisions pertaining to events and disputes. The only extant example of an ancient Greek theatre trilogy, the Oresteia won first prize at the Dionysia festival in 458 BCE. The principal themes of the trilogy include the contrast between revenge and justice, as well as the transition from personal vendetta to organized litigation.  Oresteia originally included a satyr play, Proteus (Πρωτεύς), following the tragic trilogy, but all except a single line of Proteus has been lost.Agamemnon
Agamemnon (Ἀγαμέμνων, Agamémnōn) is the first of the three plays within the Oresteia trilogy. It details the homecoming of Agamemnon, King of Mycenae, from the Trojan War. After ten years of warfare, Troy had fallen and all of Greece could lay claim to victory. Waiting at home for Agamemnon is his wife, Queen Clytemnestra, who has been planning his murder. She desires his death to avenge the sacrifice of her daughter Iphigenia, to exterminate the only thing hindering her from commandeering the crown, and to finally be able to publicly embrace her long-time lover Aegisthus.The play opens to a watchman looking down and over the sea, reporting that he has been lying restless "like a dog" for a year, waiting to see some sort of signal confirming a Greek victory in Troy. He laments the fortunes of the house, but promises to keep silent: "A huge ox has stepped onto my tongue." The watchman sees a light far off in the distance—a bonfire signaling Troy's fall—and is overjoyed at the victory and hopes for the hasty return of his King, as the house has "wallowed" in his absence. Clytemnestra is introduced to the audience and she declares that there will be celebrations and sacrifices throughout the city as Agamemnon and his army return.Upon the return of Agamemnon, his wife laments in full view of Argos how horrible the wait for her husband, and King, has been. After her soliloquy, Clytemnestra pleads with and persuades Agamemnon to walk on the robes laid out for him. This is a very ominous moment in the play as loyalties and motives are questioned. The King's new concubine, Cassandra, is now introduced and this immediately spawns hatred from the queen, Clytemnestra. Cassandra is ordered out of her chariot and to the altar where, once she is alone, she is heard crying out insane prophecies to Apollo about the death of Agamemnon and her own shared fate.The Eumenides
The final play of the Oresteia, called The Eumenides (Εὐμενίδες, Eumenídes), illustrates how the sequence of events in the trilogy ends up in the development of social order or a proper judicial system in Athenian society. In this play, Orestes is hunted and tormented by the Furies, a trio of goddesses known to be the instruments of justice, who are also referred to as the "Gracious Ones" (Eumenides). They relentlessly pursue Orestes for the killing of his mother. Through the intervention of Apollo, Orestes is able to escape them for a brief moment while they are asleep and head to Athens under the protection of Hermes. Seeing the Furies asleep, Clytemnestra's ghost comes to wake them up to obtain justice on her son Orestes for killing her.After waking up, the Furies hunt Orestes again and when they find him, Orestes pleads to the goddess Athena for help. She responds by setting up a trial for him in Athens on the Areopagus. This trial is made up of a group of twelve Athenian citizens and is supervised by Athena. Here Orestes is used as a trial dummy by Athena to set-up the first courtroom trial. He is also the object of the Furies, Apollo, and Athena. After the trial comes to an end, the votes are tied. Athena casts the deciding vote and determines that Orestes will not be killed. This does not sit well with the Furies but Athena eventually persuades them to accept the decision; instead of violently retaliating against wrongdoers, become a constructive force of vigilance in Athens. She then changes their names from the Furies to "the Eumenides" which means "the Gracious Ones". Athena then ultimately rules that all trials must henceforth be settled in court rather than being carried out personally.Mother-right and father-right
To the anthropologist Johann Jakob Bachofen (Das Mutterrecht, 1861), the Oresteia shows Ancient Greece's transition from "hetaerism" (polyamory) to monogamy; and from "mother-right" (matriarchal lineage) to "father-right" (patriarchal lineage). According to Bachofen, religious laws changed in this period: the Apollo and Athena of The Eumenides present the patriarchal view. The Furies contrast what they call "gods of new descent" with the view that matricide is more serious than the killing of men. With Athena acquitting Orestes, and the Furies working for the new gods, The Eumenides shows the newfound dominance of father-right over mother-right.Bachofen's interpretation was influential among Marxists and feminists. Feminist Simone de Beauvoir wrote in The Second Sex (1949) that the tribunal saw Orestes as son of Agamemnon before being son of Clytemnestra. In The Origin of the Family, Private Property and the State (1884), Marxist Friedrich Engels praises Bachofen's "correct interpretation". Nonetheless, he sees it as "pure mysticism" by Bachofen to see the change in divine perspectives as the cause of the change in Greek society. Instead, Engels considers economic factors—the creation of private property—and the "natural sexual behaviour" of men and women. For the feminist Kate Millet, the latter factor is mistaken, and The Eumenides is important in documenting the state's arguments for repression of women.
