How does Odysseus get away from the Circe?

Odysseus escapes from Circe with the help of the god Hermes, who provides him with a magical herb called moly to protect him from her sorcery. After staying with Circe for a year, he convinces her to let him leave by appealing to her desire for him to return home safely. She ultimately assists him by providing guidance on how to navigate the challenges he will face on his journey, including advice about the Sirens and the underworld. With this newfound knowledge, Odysseus sets sail once more, continuing his quest to return to Ithaca.
