Hecate.
A daughter of Perses and Asteria, Hecate is often linked with Artemis (Diana) and Selene (Luna) as a triple goddess representing the netherworld, the earth, and the moon. She is particularly confused with Artemis, and their roles do overlap. She was a goddess of fertility, women, and the moon, but she also had powers in courts of law and assemblies and could grant victory in war and athletics. She nurtured children as well, but her main powers lay in the occult and sorcery. Like the Roman Diana, she was known as goddess of the crossroads, with the epithet “trivia” (“three roads”), haunting crossroads and graveyards by night, seen only by barking dogs. Attendant on Persephone (Proserpine), she aided Demeter in the search for her daughter.
       In artistic representations, Hecate is usually depicted as one of the triple deities or as goddess of the crossroads.
