It is in the neighbourhood of Zaffran (if the measurements of Edrisi be correct) that we must look for the remains of the city of Sort or Sert. They are placed by this geographer at two hundred and thirty Arabic, or two hundred and forty-six geographic, miles from Tripoly: at least such is the distance given in the gross; for the detail (as Major Rennell has already observed) allows no more than two hundred and ten Arabic miles, or two hundred and twenty-two geographic. The first distance, of two hundred and forty-six geographic miles, would carry us seven miles beyond Zaffran, and within three of Jedeed, which is ten miles to the eastward of Zaffran. The distance in detail, or two hundred and twenty-two geographical miles, would bring us within two miles of Jiraff, and fourteen beyond Mahad Hassan; while the number of days allotted by Edrisi, for the journey in question from Tripoly to Sort, which is eleven, would give a distance (on the computation of Major Rennell) of two hundred geographic miles only; and this would bring us within six miles of Mahad Hassan, that is, six miles to the westward of that place. These measurements, considered with reference to the places enumerated, would induce us to place the city of Sort either at Mahad Hassan, or at Zaffran, or perhaps in the neighbourhood of Jedeed; for it is at these places that the greatest assemblage of ruins may be observed. To the westward of Mahad Hassan is the marsh, and at Jiraff there are nothing but sand-hills. Between Jedeed and Shuaisha[1] there are a good many scattered ground-plans, apparently of slightly-built dwelling-houses (which seem to be those pointed out by Signor Della Cella as the remains of the Charax of Strabo,) and many insulated forts, and other scattered remains of building, may be observed on the road from Jedeed to Medīnét Sultàn. It appears, on the authority of Leo Africanus, that there was nothing more remaining, in his time, of the city of Sort (or, as he writes it, Sert,) than a few inconsiderable vestiges of the walls[2]; and, if this statement is to be taken literally, it will scarcely be possible to fix the site of the town with any accuracy in a tract of country where ruins abound. We will content ourselves with repeating, that it may either be placed (upon the authority of the measurements stated above) at Mahad Hassan, at Zaffran, or in the neighbourhood of Jedeed; but if we are to fix it on the authority of Abulfeda, we must remove it further eastward, to the neighbourhood of Medīnét Sultàn, which is the spot we should ourselves prefer for it. Abulfeda, in mentioning the remains of the city of Sort, informs us that on the _west_ of them is a Gulf called Rodaik, or Rodakiah, (apparently the same) says Major Rennell (with the Zadic Sinus of Edrisi) near which stands the town of Asna, one hundred and two Arabic miles, or one hundred and eight geographic, to the south-east of the Promontory of Kanem.
