Note 2377 — BOOK IV. AN ACCOUNT OF COUNTRIES, NATIONS, SEAS, TOWNS, HAVENS, MOUNTAINS, RIVERS, DISTANCES, AND PEOPLES WHO NOW EXIST OR FORMERLY EXISTED.
John Bostock translation
From τραχὺς, “narrow,” in allusion to the narrowness of the mountain passes. Brotier places it on the site of the modern Zeitoun, but he is probably in error.
