The Triple Goddess is a deity or deity archetype revered in many Neopagan religious and spiritual traditions. In common Neopagan usage, the Triple Goddess is viewed as a triunity of three distinct aspects or figures united in one being. These three figures are often described as the Maiden, the Mother, and the Crone, each of which symbolizes both a separate stage in the female life cycle and a phase of the Moon, and often rules one of the realms of heavens, earth, and underworld. In various forms of Wicca, her masculine consort is the Horned God.
The Triple Goddess was the subject of much of the writing of early and middle 20th-century poet, novelist and mythographer Robert Graves, in his books The White Goddess and The Greek Myths as well as in his poetry and novels. Modern neopagan conceptions of the Triple Goddess have been heavily influenced by Graves, who regarded her as the continuing muse of all true poetry, and who speculatively imagined her ancient worship, drawing on the scholarship, fiction and mythology of his time, in particular the work of Jane Ellen Harrison and other Cambridge Ritualists. Hungarian scholar of Greek mythology Karl Kerenyi likewise perceived an underlying triple moon goddess in Greek mythology. Archaeologist Marija Gimbutas also argued for the ancient worship of a universal Triple Goddess in European cultures but, as with Graves, her generalization of these theories to multiple unrelated cultures, and the unsourced homogenization of diverse cultures into one unified cultural and religious figure, has attracted much controversy. Many neopagan belief systems follow Graves' and Gimbutas' proposed figure of a universal, cross-cultural Triple Goddess, and these ideas continue to be an influence on feminism, literature, Jungian psychology and literary criticism.
Various triune or triple goddesses, or deities who appeared in groupings of three, were known to ancient religion. Well-known examples include Tridevi (Saraswati, Lakshmi, Kali), the Charites (Graces), the Horae (Seasons, of which there were three in the ancient Hellenistic reckoning), and the Moirai (Fates).
