The term 'Goddess of the Underworld' refers to two deities in Greek and Roman mythology: Proserpina (also known as Persephone) and Hecate. Proserpina was the daughter of Zeus and Demeter, and was abducted by Hades, the god of the underworld, to be his wife. Hecate was a goddess associated with magic, crossroads, and the underworld. She was often depicted as a three-headed figure, and was sometimes referred to as the Queen of the Night. Both Proserpina and Hecate were associated with the underworld and the afterlife, and were worshipped by those seeking protection from evil spirits.
