Eurycleia goes upstairs to call Penelope, who has slept through the entire fight. Penelope doesn’t believe anything that Eurycleia says, and she remains in disbelief even when she comes downstairs and sees her husband with her own eyes. Telemachus rebukes her for not greeting Odysseus more lovingly after his long absence, but Odysseus has other problems to worry about. He has just killed all of the noble young men of Ithaca—their parents will surely be greatly distressed. He decides that he and his family will need to lay low at their farm for a while. In the meantime, a minstrel strikes up a happy song so that no passers-by will suspect what has taken place in the palace.
Penelope remains wary, afraid that a god is playing a trick on her. She orders Eurycleia to move her bridal bed, and Odysseus suddenly flares up at her that their bed is immovable, explaining how it is built from the trunk of an olive tree around which the house had been constructed. Hearing him recount these details, she knows that this man must be her husband. They get reacquainted and, afterward, Odysseus gives his wife a brief account of his wanderings. He also tells her about the trip that he must make to fulfill the prophecy of Tiresias in Book 11. The next day, he leaves with Telemachus for Laertes’ orchard. He gives Penelope instructions not to leave her room or receive any visitors. Athena cloaks Odysseus and Telemachus in darkness so that no one will see them as they walk through the town.
The scene changes abruptly. Hermes leads the souls of the suitors, crying like bats, into Hades. Agamemnon and Achilles argue over who had the better death. Agamemnon describes Achilles’ funeral in detail. They see the suitors coming in and ask how so many noble young men met their end. The suitor Amphimedon, whom Agamemnon knew in life, gives a brief account of their ruin, pinning most of the blame on Penelope and her indecision. Agamemnon contrasts the constancy of Penelope with the treachery of Clytemnestra.
Back in Ithaca, Odysseus travels to Laertes’ farm. He sends his servants into the house so that he can be alone with his father in the gardens. Odysseus finds that Laertes has aged prematurely out of grief for his son and wife. He doesn’t recognize Odysseus, and Odysseus doesn’t immediately reveal himself, pretending instead that he is someone who once knew and befriended Odysseus. But when Laertes begins to cry at the memory of Odysseus, Odysseus throws his arms around Laertes and kisses him. He proves his identity with the scar and with his memories of the fruit trees that Laertes gave him when he was a little boy. He tells Laertes how he has avenged himself upon the suitors.
Laertes and Odysseus have lunch together. Dolius, the father of Melanthius and Melantho, joins them. While they eat, the goddess Rumor flies through the city spreading the news of the massacre at the palace. The parents of the suitors hold an assembly at which they assess how to respond. Halitherses, the elder prophet, argues that the suitors merely got what they deserved for their wickedness, but Eupithes, Antinous’s father, encourages the parents to seek revenge on Odysseus. Their small army tracks Odysseus to Laertes’ house, but Athena, disguised again as Mentor, decides to put a stop to the violence. Antinous’s father is the only one killed, felled by one of Laertes’ spears. Athena makes the Ithacans forget the massacre of their children and recognize Odysseus as king. Peace is thus restored.
The scene in which Penelope tests her husband’s knowledge of the bed neatly brings together several ideas that the epic has touched on before. This subtle test reveals Penelope’s clever side—the side we have seen in her ploy to use a never-to-be-finished burial shroud to put off remarriage for four years. This test not only admits Odysseus to Penelope’s arms but also sheds some light on why their love for each other is so natural in the first place. They are united by the commonality of their minds, by their love of scheming, testing, and outmaneuvering. They are kindred spirits because they are kindred wits. None of the suitors could ever replace Odysseus, just as Circe or Calypso could never replace Penelope. Literally and metaphorically, no one can move their wedding bed.
