The plot of "Posthomerica" begins where Homer's "Iliad" ends, immediately after Hector's body was regained by the Trojans. Penthesileia, a daughter of Ares, arrives at Troy with a group of Amazon warriors. They arrive from the Thermodon River. She has come to share the hardships of war and to escape her people after accidentally killing her sister; she was aiming for a stag. Priam thinks she will save Troy and kill Achilles. Andromache doesn't think Penthesileia is capable. Priam prayed to Zeus to let Penthesileia return, but he sees an eagle holding a dove, a sign that she will die. Ajax and Achilles are in the city resting. Hippoclameia tries to convince the Trojan women to fight, but Theano convinces them it is a suicidal idea. Penthesileia kills Podarces in battle. Ajax convinces Achilles that it is time to fight: Achilles kills Penthesileia by impaling her and her horse, but Achilles notices her beauty and realizes that he should have made her his wife. Thersites tells Achilles not to worry about women, Achilles eventually kills him and upsets Diomedes.
