Thyone comes from the Greeks and is the goddess who presides over the Dionysian Mysteries, known in Rome as the Bacchanalia. Thyone is the name given to Semele after she was brought to Olympus from Hades by her son Dionysus. Coincidentally, when Dionysus was in hiding as an infant, one of his wet nurses was also named Thyone. It’s possible that this was Semele incognito. This is the same manner that baby Moses was secretly given to his true mother to nurse after his rescue by Pharaoh’s daughter.
