), the central portion of the great chain of mountains which, extending in a direction nearly N. and S. with an inclination to the W. at the upper end, connects the mountains of Armenia and the Caucasus with those of Susiana and Persis.
It separates Assyria from Media, and is now represented by the middle and southern portion of the mountains of Kurdistán,
the highest of which is the well known Rowandíz.
Near this latter mountain was the great highroad which led from Assyria and its capital Nineveh into Media, and, at its base, was in all probability the site of the pass through the mountains, called by Ptolemy αἱ τοῦ Ζάγρου πύλαι
(6.2.7), and by Strabo, ἡ Μηδικὴ πύλη
(xi. p. 525). Polybius notices the difficulty and danger of this pass (5.44), which, from Colonel Rawlinson's narrative, would seem to have lost none of its dangers (Rawlinson, in Trans. Geogr. Soc.
