The Choephori - The Libation Bearers - Aeschylus The Libation Bearers is the second play of the Oresteia. It deals with the reunion of Agamemnon's children, Electra and Orestes, and their revenge. Orestes kills Clytemnestra to avenge the death of Agamemnon, Orestes' father. Storyline Orestes arrives at the grave of his father, accompanied by his cousin Pylades, the son of the king of Phocis, where he has grown up in exile; he places two locks of his hair on the tomb. Orestes and Pylades hide as Electra, Orestes' sister, arrives at the grave accompanied by a chorus of elderly slave women (the libation bearers of the title) to pour libations on Agamemnon's grave; they have been sent by Clytemnestra in an effort "to ward off harm" (l.42). Just as the ritual ends, Electra spots a lock of hair on the tomb which she recognizes as similar to her own; subsequently she sees two sets of footprints, one of which has proportions similar to hers. At this point Orestes and Pylades emerge from their hiding place and Orestes gradually convinces her of his identity. Now, in the longest and most structurally complex lyric passage in extant Greek tragedy, the chorus, Orestes, and Electra, attempt to conjure the departed spirit of Agamemnon to aid them in revenging his murder. Orestes then asks "why she sent libations, what calculation led her to offer too late atonement for a hurt past cure" (l.515
