The Odyssey is an ancient Greek epic poem following the wanderings of Odysseus on his return from the Trojan War. As such, it is a sequel to the Iliad, although its exact relationship to the earlier poem is as controversial as the historical existence of Homer, the traditional author of both epics. As with the Iliad, the story opens 'in the middle of things' with Odysseus held captive by the goddess Calypso. His adventures in the ten years since the fall of Troy are recounted as the story advances towards his final homecoming.
