Orphism, in classical religion, mystic cult of ancient Greece, believed to have been drawn from the writings of the legendary poet and musician Orpheus. Fragmentary poetic passages, including inscriptions on gold tablets found in the graves of Orphic followers from the 6th century bc, indicate that Orphism was based on a cosmogony that centered on the myth of the god Dionysus Zagreus, the son of the deities Zeus and Persephone. Furious because Zeus wished to make his son ruler of the universe, the jealous Titans dismembered and devoured the young god. Athena, goddess of wisdom, was able to rescue his heart, which she brought to Zeus, who swallowed it and gave birth to a new Dionysus. Zeus then punished the Titans by destroying them with his lightning and from their ashes created the human race. As a result, humans had a dual nature: the earthly body was the heritage of the earth-born Titans; the soul came from the divinity of Dionysus, whose remains had been mingled with that of the Titans.

According to the tenets of Orphism, people should endeavor to rid themselves of the Titanic or evil element in their nature and should seek to preserve the Dionysiac or divine nature of their being. The triumph of the Dionysiac element would be assured by following the Orphic rites of purification and asceticism. Through a long series of reincarnated lives, people would prepare for the afterlife. If they had lived in evil, they would be punished, but if they had lived in holiness, after death their souls would be completely liberated from Titanic elements and reunited with the divinity.
