Trachoni´tis was, in the days of the Herodian dynasty, the name of the country situated between the Antilibanus and the Arabian mountains south of Damascus and west of the provinces of Batanaea, Gaulonitis, Ituraea, and Auranitis, under about the thirty-third degree of northern latitude. It is at present called Ledja. The eastern range of mountains is now called Jebel Manai, and contains great caverns in chalk rocks. The southern portions of the ancient Trachonitis, or the present Ledja, consist chiefly of basalt rocks.
