or Nyssa, in Ancient Geography, a town of Ethiopia, at the south of Egypt. Some place it in Arabia. This city, with another of the same name in India, was sacred to the god Bacchus, who was educated there by the nymphs of the place, and who received the name of Dionysus, which seems to be compounded of Διος and Νύσσα, the name of his father, and that of the place of his education. The god made this place the seat of his empire, and the capital of the conquered nations of the east. According to some geographers, there were no less than ten places of this name. One of these was famous on the coast of Euboea, for its vines, which grew in such a uncommon manner, that if a twig was planted in the ground in the morning, it immediately produced grapes which were full ripe in the evening. A city of Thrace: another seated on the top of Mount Parnassus, and sacred to Bacchus.
