The Orphic theogonies are genealogical works similar to the Theogony of Hesiod, but the details are different.
There are two Orphic stories of the rebirth of Dionysus: in one it is the heart of Dionysus that is implanted into the thigh of Zeus; in the other Zeus has impregnated the mortal woman Semele, resulting in Dionysus's literal rebirth.
