These Copheral Turks invaded Persia about fifteen years ago, about 1145, with a great army, and destroyed the metropolitan city of Rei[18], and carried off vast spoil into the desert. Enraged at this insult, the king of Persia endeavoured to pursue them with a powerful army, that he might extirpate these destroyers from the earth, and procured a guide who undertook to conduct him to their dwellings, and recommended to him to take bread and water for fifteen days along with the army, as it would occupy that time to pass the deserts. After marching these fifteen days, the army was without subsistence for man and beast, and no signs could be perceived of any habitation of mankind. On being interrogated, the guide pretended to have lost his way, and was put to death as a traitor. After marching for thirteen days more, in prodigious distress, during which they had to eat up all the beasts that carried their baggage, they arrived at the mountains of Nisbor, inhabited by the Jews, and incamped among gardens and orchards, watered by canals drawn from the river Gozan; and being then the season of ripe fruits, they eat what they pleased, no one appearing to oppose them. At a distance among the mountains, they observed some hamlets and forts, and two scouts were sent to discover what manner of people inhabited the mountains. After proceeding a short way, they found a well built bridge, with a strong barrier, and a very large city at the farther end of the bridge. They here learned, by an interpreter, that the city belonged to an independent nation of Jews, who had a prince of their own, and were in alliance with the Copheral Turks.
