Circe invites the hero Odysseus' crew to a feast of familiar food, a pottage of cheese and meal, sweetened with honey and laced with wine, but also mixed with one of her magical potions that turns them into swine. Only Eurylochus, who suspects treachery, does not go in. He escapes to warn Odysseus and the others who have remained with the ship. Before Odysseus reaches Circe's palace, Hermes, the messenger god sent by the goddess of wisdom Athena, intercepts him and reveals how he might defeat Circe in order to free his crew from their enchantment. Hermes provides Odysseus with moly to protect him from Circe's magic. He also tells Odysseus that he must then draw his sword and act as if he were going to attack her. From there, as Hermes foretold, Circe would ask Odysseus to bed, but Hermes advises caution, for the treacherous goddess could still "unman" him unless he has her swear by the names of the gods that she will not take any further action against him. Following this advice, Odysseus is able to free his men.
