The town is some two miles in length and perhaps half a mile in width, and is reputed to contain about 80,000 inhabitants. It is built of a warm-coloured stone similar to that employed at Urfa; and, like Urfa, is largely composed of good substantial buildings, which can sustain a certain amount of dilapidation without lapsing altogether into squalor. The streets are narrow and tortuous, and run for the most part longitudinally; thus it is evident that the cliff which overhangs them cannot (like the Amadia cliff) be in the habit of dropping fragments down the slope beneath it; otherwise the lanes would run vertically, and be a good deal wider than they are! Some of the principal mosques possess considerable architectural pretensions, with Arabesque stalactite corbelling inserted in the coves over the doorways, and a certain amount of good carving introduced here and there on the facades. They are generally covered with fluted domes--a rather unusual feature, but one which is very conducive to the general effectiveness of the design. Mardin is a walled city, but its walls were never very formidable and are now mostly ruinous. They consist but of broken fragments even on the citadel rock. The place was no Roman fortalice like Urfa or Diarbekr, and the part that it played in history was not of any great note. For some time it was the capital city of a petty dynasty of little independent Sultans; and the tomb of one of the most powerful of these forms a graceful adjunct to one of the chief mosques. One unique distinction, however, belongs to its rock-perched citadel. This is said to have held out successfully against the invincible Timour himself. Mardin is in these days best known to us as the residence of the Patriarch of the Jacobites--Mar Ignatius, the modern inheritor of the throne of Antioch, that earliest of all Metropolitan sees. He resides at Deir el Za'aferan, the "Monastery of the Yellow Rocks," which is situated about five miles eastward upon the southern slope of the mountains, in a position very similar to that of the town itself but on a separate hill. Deir el Za'aferan is a very ancient foundation dating from the fifth or sixth century; and certain fragments of its original structure still survive to this day, incorporated in the existing buildings. They are of pronouncedly classical character, and display a strong similarity to the admittedly Roman work in the Church of St. James at Nisibin: but the major part of the monastery is of much more modern construction; for it has been almost constantly occupied ever since the date of its erection, and subjected to many vicissitudes, being frequently ruined and rebuilt. The Syrian "Jacobite" Christians are a poor remnant now, but they were once the dominant Church in that group of old Roman provinces that we style loosely, "Syria and Palestine," but which Romans called "The Orient," _Praefactura Orientalis_.
