There are two mounts of ruins near the Eastern extremity of the town, on the most Northern of which is a piece of brick wall remarkably strong, which is reported to have been part of an ancient castle. From this elevation is seen the field of battle between the Christians and Saracens, in which St. Louis was, according to the Arabs, taken prisoner. It is called the _field of blood_, as the conflict is represented as having been so obstinate, that the earth and water were stained with blood for a considerable time after. There is nothing farther worthy of remark in this town, except two mosques. One of them is a rich foundation of the same nature as the _Jama-el-Azher_, which it is said maintains five or six hundred poor shechs, many of whom are blind or paralytic. The other is an old and famous mosque, which has been raised, as is said, on the ruins of a Christian church, part of which is reported to exist under the building. Even the mosque itself is now deserted, and in a great measure fallen to ruin; the door which leads to the passage below is bricked up, so that I could make no observations on that part. The mosque is spacious, and contains a great number of marble columns. I observed, however, only one of porphyry, and one of red granite. The rest are of common blue and white, and yellow and white marble; one of the latter is reported to have the virtue of curing the jaundice; and for this purpose the poor people affected with this disorder scrape it and drink the powder, which is in such repute that a considerable cavity may be observed in the column. Another fine porphyry column I was told was lately carried away by a Mokaddem of the Bey, employed in collecting his rents here, for the purpose of forming a tomb for himself. The population of Damiatt may be partly conceived from the number of its mosques, which are supposed to be fourteen. There is also a Greek convent, in which strangers are lodged, there being no caravanserai in the place. The lake _Manzalé_ is of very considerable extent, being somewhat more than thirty miles in length, and is navigated by a number of small vessels employed in fishing, and in carrying the people to and from the islands. The fish called _Bûri_, a kind of mullet, particularly abounds; it is salted and dried at Damiatt, whence it is conveyed through the Lower Egypt and Syria, and even to Cyprus. It affords an insipid and insalubrious meal; yet is much used by the common people, especially by the Christians in their frequent fasts. The desert islands interspersed in the lake are haunted by numbers of aquatic birds, which migrate thither in autumn and winter: they are ensnared in nets, and furnish a livelihood to many of the lower class of the people, who sell them in the markets. The water of this lake is brackish, but not very salt. Where the most easterly branch of the Nile fell into it, still remain some ruins of the antient city of Tanis, which I had not an opportunity of visiting.
