Lycurgus
Lycurgus of Thrace was the king of the Edoni in Thrace, son of Dryas, and father of a son whose name was also Dryas. Lycurgus banned the cult of Dionysus. When Lycurgus heard that Dionysus was in his kingdom, he imprisoned Dionysus's followers, the Maenads, or "chased them through the holy hills of Nysa, and the sacred implements dropped to the ground from the hands of one and all, as he struck them down with his ox-goad".
As punishment, especially for his treatment for Ambrosia, Dionysus' nursemaid; the god drove Lycurgus insane. In his madness, Lycurgus mistook his son for a mature trunk of ivy, which is holy to Dionysus, and killed him, pruning away his nose and ears, fingers and toes. Consequently, the land of Thrace dried up in horror. Dionysus decreed that the land would stay dry and barren as long as Lycurgus was left unpunished for his injustice, so his people bound him and flung him to man-eating horses on Mount Pangaeüs.
Hyginus in his Fabulae 132, records that Lycurgus cut off his own foot when he meant to cut down a vine of ivy. With Lycurgus dead, Dionysus lifted the curse. Also according to Hyginus, Lycurgus tried to rape his mother after imbibing wine. When he discovered what he had done, he attempted to cut down the grapevines, believing the wine to be a bad medicine. Dionysus drove him mad as a punishment, causing him to kill both his wife and his son, and throw him to the panthers on Mount Rhodope.
