In Greek legend, sorceress Circe (pronounced Kirke) is the daughter of Helios, the sun god, and Perse, an ocean nymph. She is said to have been surrounded by beasts that could not be seen elsewhere. When others came to her palace, they saw the beasts, but only what they recognized, like lions, bears and wolves. The beasts acted as domesticated animals, showing their kindness by wagging their tails. Some say they were actually drugged victims of Circe.
