Penelope gets Odysseus’s bow out of the storeroom and announces that she will marry the suitor who can string it and then shoot an arrow through a line of twelve axes. Telemachus sets up the axes and then tries his own hand at the bow, but fails in his attempt to string it. The suitors warm and grease the bow to make it supple, but one by one they all try and fail.
Meanwhile, Odysseus follows Eumaeus and Philoetius outside. He assures himself of their loyalty and then reveals his identity to them by means of the scar on his foot. He promises to treat them as Telemachus’s brothers if they fight by his side against the suitors.
When Odysseus returns, Eurymachus has the bow. He feels disgraced that he cannot string it, because he knows that this failure proves his inferiority to Odysseus. Antinous suggests that they adjourn until the next day, when they can sacrifice to Apollo, the archer god, before trying again. Odysseus, still disguised, then asks for the bow. All of the suitors complain, fearing that he will succeed. Antinous ridicules Odysseus, saying that the wine has gone to his head and that he will bring disaster upon himself, just like the legendary drunken centaur Eurytion. Telemachus takes control and orders Eumaeus to give Odysseus the bow. Needless to say, Odysseus easily strings it and sends the first arrow he grabs whistling through all twelve axes.
Before the suitors realize what is happening, Odysseus shoots a second arrow through the throat of Antinous. The suitors are confused and believe this shooting to be an accident. Odysseus finally reveals himself, and the suitors become terrified. They have no way out, since Philoetius has locked the front door and Eumaeus has locked the doors to the women’s quarters. Eurymachus tries to calm Odysseus down, insisting that Antinous was the only bad apple among them, but Odysseus announces that he will spare none of them. Eurymachus then charges Odysseus, but he is cut down by another arrow. Amphinomus is the next to fall, at the spear of Telemachus.
Telemachus gets more shields and swords from the storeroom to arm Eumaeus and Philoetius, but he forgets to lock it on his way out. Melanthius soon reaches the storeroom and gets out fresh arms for the suitors. He isn’t so lucky on his second trip to the storeroom, however, as Eumaeus and Philoetius find him there, tie him up, and lock him in.
A full battle now rages in the palace hall. Athena appears disguised as Mentor and encourages Odysseus but doesn’t participate immediately, preferring instead to test Odysseus’s strength. Volleys of spears are exchanged, and Odysseus and his men kill several suitors while receiving only superficial wounds themselves. Finally, Athena joins the battle, which then ends swiftly. Odysseus spares only the minstrel Phemius and the herald Medon, unwilling participants in the suitors’ profligacy. The priest Leodes begs unsuccessfully for mercy.
