Hecate

Greek goddess of magic and spells. She probably originated in Asia Minor.

Hesiod held her to be the daughter of the Titan Perses and represented her as the bestower of wealth and the blessings of daily life. She witnessed the abduction of Persephone by Hades and assisted in the search for her. Pillars called Hecataea were erected at doorways and crossroads to ward off evil spirits. She was sometimes depicted as three bodies back to back, so that she could look in all directions at a crossroads.
