Zareth-shahar
the splendour of the dawn, a city "in the mount of the valley"
(Josh. 13:19). It is identified with the ruins of Zara, near the
mouth of the Wady Zerka Main, on the eastern shore of the Dead
Sea, some 3 miles south of the Callirrhoe. Of this town but
little remains. "A few broken basaltic columns and pieces of
wall about 200 yards back from the shore, and a ruined fort
rather nearer the sea, about the middle of the coast line of the
plain, are all that are left" (Tristram's Land of Moab).
