A small fortress, "little stronghold" near Jericho (1 Macc 16:15), built by Ptolemy, son of Abubus, where he entertained and murdered his father-in-lawand his two sons. Josephus (Ant., XIII, viii, 1; BJ, I, ii, 3) calls the place Dagon and places it above Jericho. The name persists in Ain Duk with its copious springs of excellent water about 4 miles Northwest of Jericho. Some ancient foundations in the neighborhood are possibly those of Ptolemy’s fortress, but more probably of a Templars’ station which is known to have stood there as late as the end of the 13th century. For its importance in earlier Jewish history, see Smith, HGHL, 250, 251.
