In Greek mythology, Circe was a goddess of magic who lived alone on an island named Aeaea in the Mediterranean Sea. Her father was Helios, the god of the sun; her mother was Perse. She was the sister of Colchis, Aetes, Perses, and Pasiphae (the mother of the Minotaur on Crete.) She could change her enemies into animals by using various potions, and was knowledgeable about drugs and herbs. She purified the Argonauts. She was also described as a witch or enchantress. In the Odyssey by the Greek poet Homer, Odysseus and his warriors stayed on her island for a year, and by getting advice from Hermes, Odysseus was able to have sex with her while avoiding the danger of her treachery by following instructions from the messenger god.
