Hecate

Hekate is a goddess who was capable of both good and evil. She was especially associated with witchcraft, magic, the Moon, doorways, and creatures of the night such as hell-hounds and ghosts. She is often depicted carrying a torch to remind of her connection with the night and in sculpture with three faces, representing her role as the guardian of crossroads.
Genealogy
According to Hesiod in his Theogony, Hecate is the daughter of Perses and Asteria, making her the granddaughter of the Titans Phoebe and Coeus. Other writers claim her as the daughter of Zeus and Demeter.
Known as Aristaion or Night. The goddess was frequently associated with Demeter and even assimilated to her in some cults.
Associations & Rituals
the goddess is associated with the darker side of the human experience, that is death, witchcraft, magic, the Moon, dreams, fierce hounds and creatures which roam the darkness of night.
…outlandish in her infernal aspects, she is more at home on the fringes. Intrinsically ambivalent and polymorphous, she straddles conventional boundaries and eludes definition.
Hesiod describes the goddess in the following glowing terms:
Zeus, Cronus’ son, honoured [Hecate] above all others: he gave her splendid gifts - to have a share of the earth and of the barren sea, and from the starry sky as well she has a share in honour, and is honoured most of all by the immortal gods. For even now, whenever any human on the earth seeks propitiation by performing fine sacrifices according to custom, he invokes Hecate; and much honour very easily stays with that man whose prayers the goddess accepts with gladness, and she bestows happiness upon him.
Hesiod goes on to say that the goddess supports warriors, athletes, hunters, horsemen, herdsmen, shepherds, fishermen, and children.
Her companions are the Furies (Erinyes), the winged creatures who punished wrong-doing, and her children are the Empusae, female demons partial to seducing travellers.
The Temple of Hecate in Lagina, Caria
The goddess had unusual rituals performed in her honour, which include the offerings of food - given at crossroads, road junctions, and any other sort of boundary or threshold - known as 'the supper of Hecate'. These took the form of small cakes of eggs, cheese, bread, and dog meat, which were lit with miniature torches or, alternatively, a dish of red mullet, which was usually prohibited from offerings to the other gods. Hecate was also offered the sacrifice of dogs, especially puppies. The dog connection may be the fact that dogs were known to eat the dead if left unburied; they also howl at the moon, of course. A further canine connection may be with the Egyptian god Anubis who guided souls to the underworld, and the Greek three-headed hound of Hades, Cerberus, may be an earlier form of Hecate. The offerings to the goddess were made each month during the night of a new moon. The goddess was especially appealed to by sorceresses for aid in their magic and spells and appears on surviving examples of curse tablets.
IT WAS A COMMON PRACTICE TO PLACE IMAGES OF HECATE AT CITY GATES & THE DOORWAYS OF PRIVATE HOMES AS SHE COULD WARD OFF EVIL SPIRITS.
According to Pausanias, the traveller, the island of Aegina had a mystery cult dedicated to the goddess where it was believed those suffering mental illness could o worshipped the goddess, with the latter having a CE circular altar for sacrifices to be made in her honour (the earliest archaeological evidence of her worship). The worship of Hecate continues in hidden places.
