Nysa was a mythical place in Greek mythology where the young god Dionysus was raised. The exact location of Nysa varies in the myths; locations include Ethiopia, Anatolia, Libya, Tribalia (nowdays Serbia), and Arabia. Greek concepts of where Nysa was, are variable enough to suggest that a magical distant land was named 'Nysa' to explain the god's unreadable name, as the 'god of Nysa'. Infant Dionysus, god of the grapevine, was nursed by the rain-nymphs, the Hyades at Nysa.
