'' (RRC 486/1) depicting the head of Diana and her triple cult statue The Roman goddess
Diana was venerated from the late sixth century BC as
diva triformis, "three-form goddess", and early on was conflated with the similarly depicted Greek goddess
Hekate.
Andreas Alföldi interpreted a late Republican numismatic image as Diana "conceived as a threefold unity of the divine huntress, the Moon goddess and the goddess of the nether world,
Hekate". This coin shows that the triple goddess cult image still stood in the
lucus of Nemi in 43 BC. The
Lake of Nemi was
Triviae lacus for Virgil (
Aeneid 7.516), while
Horace called Diana
montium custos nemoremque virgo ("keeper of the mountains and virgin of Nemi") and
diva triformis ("three-form goddess"). Spells and hymns in
Greek magical papyri refer to the goddess (called
Hecate,
Persephone, and
Selene, among other names) as "triple-sounding, triple-headed, triple-voiced..., triple-pointed, triple-faced, triple-necked". In one hymn, for instance, the "Three-faced Selene" is simultaneously identified as the three
Charites, the three
Moirai, and the three
Erinyes; she is further addressed by the titles of several goddesses. Translation editor
Hans Dieter Betz notes: "The goddess Hekate, identical with Persephone, Selene, Artemis, and the old Babylonian goddess
Ereschigal, is one of the deities most often invoked in the papyri."
E. Cobham Brewer's 1894
Dictionary of Phrase & Fable contained the entry, "
Hecate: A triple deity, called
Phoebe or the Moon in heaven,
Diana on the earth, and Hecate or
Proserpine in hell," and noted that "Chinese have the triple goddess Pussa". The Roman poet
Ovid, through the character of the Greek woman
Medea, refers to Hecate as "the triple Goddess"; the earlier Greek poet
Hesiod represents her as a threefold goddess, with a share in earth, sea, and starry heavens. Hecate was depicted variously as a single womanly form; as three women back-to-back; as a three-headed woman, sometimes with the heads of animals; or as three upper bodies of women springing from a single lower body ("we see three heads and shoulders and six hands, but the lower part of her body is single, and closely resembles that of the Ephesian Artemis".) The Olympian
demiurgic triad in
platonic philosophy was made up of Zeus (considered the Zeus [king of the gods] of the
Heavens),
Poseidon (Zeus of the
seas) and
Pluto/
Hades (Zeus of the
underworld). All were considered to be ultimately a
monad; the same Zeus who gave rise to the
Titanic demiurgic triad of
Helios (the sun when in the sky), Apollo (the sun seen in the world of humankind), and
Dionysus (god of
mysteries, or the "sun" of the underworld), as in
Plato's
Phaedrus, concerning the myth of Dionysus and the Titans) ==Ancient Celtic cultures==
