Oresteia has part(s) Eumenides
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.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.
