From Quiz Divine Ladies of Greek Mythology
Answer:
Hecate
In Hesiod's "Theogony", Hecate ("the far-reaching one") is the daughter of the Titans Perses and Asteria. Other sources describe her as a daughter of Zeus and Demeter, and thus sister to Persephone, the queen of the Underworld. In various classical texts, Hecate helped Demeter in her search for her daughter, abducted by Hades, and eventually became Persephone's minister and companion. Sometimes described as a virgin goddess, Hecate shared some of the attributes of Artemis and Selene, both deities associated with the moon. She was often depicted with three joined bodies, a reference to her manifold nature, holding flaming torches, keys or daggers, or accompanied by her familiars - a black dog, a polecat or a snake, all animals connected to the underworld.
Though widely worshipped both in Greece and Rome, Hecate was more of a fringe deity than a mainstream one, particularly because of her strong association with the occult: in Euripides' tragedy "Medea", she is mentioned as the source of Medea's magical powers. However, she was also revered as a protector of households, boundaries and crossroads. Indeed, in Ancient Rome she was given the epithet of Trivia ("three ways"), on account of her triple form that allowed her to keep watch over various directions. Hecate briefly appears as a character in William Shakespeare's "Macbeth".
