Hecate is a chthonic goddess in Greek religion and mythology, associated with crossroads, entrance-ways, dogs, light, the moon, magic, witchcraft, knowledge of herbs and poisonous plants, ghosts, necromancy, and sorcery. She reigns as goddess of the three paths, guardian of the household, protector of everything newly born, and the goddess of witchcraft. In the post-Christian writings of the Chaldean Oracles (2nd–3rd century CE) she was regarded with] rulership over earth, sea and sky, as well as a more universal role as Saviour (Soteira), Mother of Angels and the Cosmic World Soul.She was one of the main deities worshiped in Athenian households as a protective goddess and one who bestowed prosperity and daily blessings on the family.
A lover of solitude, the Greek goddess Hecate was, like her cousin Artemis, a "virgin" goddess, unwilling to sacrifice her independent nature for the sake of marriage. Walking the roads at night or visiting cemeteries during the dark phase of the moon, the goddess Hecate was described as shining or luminous.
In other legends she is invisible, perhaps only glimpsed as a light, a "will-o-the-wisp". Perhaps it was this luminous quality that marked Hecate as a "moon goddess", for she seemed quite at home on the earth.
