In Greek mythology, goddesses of the underworld were often used to invoke the Samhain (Samhain: A pagan holiday that is celebrated on October 31. It marks the end of Summer and the beginning of Winter).
. Popular Greek Goddess costumes portray Hecate and Medusa. Hecate was the most favored goddess by Zeus, and wandered the emptiness between the worlds of life and death looking for souls of the dead. Both were considered serpent goddesses, and their ancient dark legends spawned myths such as vampires, who fed off the living using venom and snake-like fangs. Ritualistic dress includes snake adornments and three headed masks. Today, Hecate is often referred to as the goddess of witches.
