The Odyssey opens years after the Trojan War, with every surviving Greek leader home except Ulysses, who is held on a distant island by the goddess Calypso. In Ithaca his house is besieged by suitors who feast on his wealth and press his wife Penelope to remarry. The first books follow his son Telemachus, prompted by the goddess Minerva, as he sets out to seek news of whether his father is alive.
Released at last by the will of the gods, Ulysses is shipwrecked and washes up among the Phaeacians, who receive him kindly. At their feast he reveals his name and tells the long story of his wanderings: the Lotus-eaters, the blinding of the Cyclops Polyphemus, the wind-bag of Aeolus, the enchantress Circe, the descent to the land of the dead, the Sirens, and the deadly strait of Scylla and Charybdis.
The most costly episode is the island of the Sun-god. Warned not to touch the sacred cattle, Ulysses' starving men kill them anyway while he sleeps, and for that folly the god destroys the ship and every man but Ulysses himself. He drifts alone to Calypso, where the tale rejoins the present. The Phaeacians, moved by his story, give him gifts and carry him home to Ithaca at last.
Back on his own soil, Ulysses works in disguise as a ragged stranger. He is sheltered by the faithful swineherd Eumaeus, reunites secretly with Telemachus, and studies his enemies inside his own hall. Patiently he endures insult from the suitors and gathers proof of who has stayed loyal and who has betrayed him, biding his time for the moment to strike.
The climax comes through Penelope's contest of the great bow, which only Ulysses can string. He turns the trial into a slaughter, killing the suitors with his son and loyal herdsmen, and the treacherous maids are punished. A final, quieter test follows: Penelope proves his identity by the secret of their immovable marriage-bed, and the long-delayed reunion restores husband, wife, son, and kingdom.
