A second instance of Odysseus' heroic character occurs in Book 11, when Circe instructs Odysseus to travel to the underworld, Hades, to confront the dead prophet, Teiresias, about Odysseus' fate. If Odysseus succeeds in this task, he will be able to learn how he can return home. Circe has been manipulating both men all along in an attempt to get her own way. When Odysseus refuses to help her seduce Zeus, she casts a spell on him that makes him fall in love with her. Once he is dependent on her for food and shelter, she tells him they will have to leave Greece because someone has accused him of murder. He does as he is told without question, until they reach Sicily where he fights Calypso once more for possession of his soul. This time, though, she doesn't win because it is clear that he still loves Athena and would do anything for home and family. So, Circe tricks Calypso into giving up Odysseus by telling her that if he goes home, he will never come back. After this success, she tells him they must travel to the underworld so she can ask Hades about his fate.
