    Clytamenestra told Electra and other slave women to come to the tomb of Agamemnon to pour libation bearer on it. Later, Orestes comes out and faces Electra. They discuss the plan of avenging their father's death.

    Orestes and Pylades pretend as strangers from Delphi to inform the Clytamenestra and Aegisthus about the death of Orestes. Shortly after they enter the palace, Orestes founds Aegisthus and kills him. Then, he found Clytamenestra and hesitates to kill her. Pylades, also a representation of Apollo, removes Orestes' hesitation. Orestes kills Clytamenestra. Clytamenestra tells Orestes that the fury will go after him before she dies.
