A Greek hero in the Trojan War. Odysseus helped bring about the fall of Troy by conceiving the ruse of the Trojan horse. After Troy was ruined, Odysseus wandered for ten years trying to return home, having many adventures along the way. (See Circe, Cyclops, Penelope, Scylla and Charybdis, and Sirens.)
