(anc. geog.), a citadel on the other side Jordan, near the mountains of Moab, not far from and to the north of the Lacus Asphaltites. It was the south boundary of the Perga: situated on a mountain encompassed round with deep and broad valleys; built by Alexander king of the Jews, destroyed by Gabinius in the war with Aristobulus, and rebuilt by Herod with a cognominal town round it. Here John the Baptist was beheaded (Josephus).
