Hecate is an ancient goddess who is sometimes depicted as being a triple formed goddess. She has rulership over earth, sea and sky, and is variously associated with crossroads, entrance-ways, fire, light, the Moon, magic, as well as a more universal role as Saviour (Soteira), Mother of Angels and the Cosmic World Soul.
In late Egyptian thought, the righteous dead were sometimes said to become the stars, and hence, the moon was occasionally seen as having a connection to Osiris, lord of the dead. As a death and resurrection legend, in which evil seeks to destroy a deity, thus bringing darkness, it developed an association with the lunar cycle, in which the moon appears to be destroyed by darkness, and is then brought back to life. It also became said that Osiris had been killed by being dismembered into 14 parts, though one piece went missing as it was eaten by a fish, leaving each remaining part to represent one of the 13 full moons seen each year (there are roughly 13 lunar months per year)
