When Odysseus and his men landed in Aeaea, his crew later met with Circe and were turned into pigs. Circe's spells however had no effect on Odysseus who earlier was given an herb by Hermes to resist her power. Circe realizing she was powerless over him lifted the spell from the crew and welcomed them in her home. After about a year when Odysseus leaves she warns them of the sirens they will encounter on their journey. Circe and Odysseus also bore a child together named Telegonus who later ruled over the Tyrsenians.
Circe also has the powers for spiritual purification as she purifies the Argonauts for the murder of Apsyrtus.
