He is Second in Command of Odysseus Legion. He is also the one who led some men into Circes Palace when they were turned to swine. He was the only one in that group that was not turned to swine because he feared a trap.
Circe wasn't a goddess she was a sorceress who lived on the island Aeaea and turned any men who came to her island into pigs until Odysseus stopped her with the help of the god Hermes.
Hermes warns Odysseus before his encounter with the enchantress Circe, and gives Odysseus a magical herb to protect him from Circes' spells, as well as exact advice as to what to do. Circe tries to turn Odysseus into a pig but fails. Odysseus rushes Circe with his sword, but she acquiesces, and tries to bed Odysseus. Odysseus commands her to swear an oath to do him no further harm, and after she has, he beds her. Afterwards he refuses to eat, and explains he cannot until he sees his men. Circe retrieves them (as animals), and administers a drug to turn them back into normal. Odysseus tells his men to return to the ship.
