Hecate is the daughter of the Titans Perses and Asteria. She is the Greek goddess of magic, sorcery, witchcraft, crossroads, trivial knowledge, and necromancy. She was associated with things including childbirth, nurturing the young, gates, walls, doorways, and sometimes even change. She resided on Olympus, in the deep sea, in the Underworld, and also on the Earth.
Hecate was the daughter of Perses and "gold-wreathed" Asteria (the starry night). Her sway extended over earth, heaven, and the Underworld. For this reason she is represented in works of art as a triple divinity, having three female bodies, all young and beautiful, and united together.
Hecate was among the few Titans who supported Zeus and the Olympians in the Titanomachy and thus was allowed to retain her authority once the Olympians came into power. For her support, Zeus gave Hecate a share in all three realms of the cosmos, for which she was known as the goddess of crossroads.
Hecate had little organized worship, as she was more commonly found on the outskirts of the old myths rather than playing an active part in it. However, Hecate did play a major role in the abduction of Persephone. After the abduction, it was Hecate who told the frantic Demeter what had become of her daughter. After the dispute between her mother and husband was settled, Hecate became Persephone's confidante when she was in the Underworld. Thankful for their friendship, Hades honored Hecate as a prominent and permanent guest in the Underworld. She now presides over all practices connected with witchcraft and enchantments, haunts sepulchers, at crossroads, and lonely spots where murders have been committed. She is connected with the appearance of ghosts and specters, to possess unlimited influence over the powers of the lower world, and to be able to lay to rest unearthly apparitions by her magic spells and incantations.
She also participated in the war between the Olympians and the Titans, immolating a giant named Clytius, with her torches.
Devotion to Hecate was especially favored by the Byzantines for her aid in having protected them from the incursions of Philip of Macedon. Her symbols were the crescent and star, and the walls of her city were her provenance.
