Odysseus' return from Troy, chronicled in the Odyssey, took ten years and was beset by perils and misfortune. He freed his men from the pleasure-giving drugs of the Lotus-Eaters, rescued them from the cannibalism of the Cyclopes and the enchantments of Circe. He braved the terrors of the underworld with them, and while in the land of the dead Hades allowed Thiresias, Odysseus' mother, Ajax and others to give him adivice on his next journey. They gave him important advice about the cattle of the sun (which Apollo herds), Scylla and Charybdis and the Sirens. From there on the travels were harder for Odysseus, but they would have been much worse of it wasn't for the help of the dead.
