Hermes, the god of messengers, stops Odysseus on his way to Circe. "He meets the god Hermes, who gives him a magical plant--called moly-- to protect him from Circe's power. Still, Hermes warns, Odysseus must make the goddess swear that she will play no 'witches tricks.'"
"Circe, am I a boy, that you should make me soft and doting now? Here in this house you turned my men into swine... I mount no bed of love with you upon it. Or swear me first a great oath, If I do, you'll work no more enchantment to my harm."
"Are you not sluggish with my wine? Ah, wonder! Never a mortal man that drank this cup but when it passed his lips he has succumbed...Odysseus then you are, O great contender... We two shall mingle and make love upon our bed."
Circe's maids bathe Odysseus, but his mind stays on his captive men. When Circe offered him a meal, Odysseus couldn't eat, only thinking about his men.
"Circe, where is the captain who could bear to touch this banquet, in my place? A decent man would see his company before him first. Put heart in me to eat and drink--you may, by freeing my companions. I must see them."
Circe feels bad for Odysseus and turns all of his men back into humans. Odysseus goes back to the rest of the people on the ship and tells them that they can stay at Circe's island. They end up staying for a year.
