When Mr. Buckingham reached the mounds of Ctesiphon, he found them to be of a moderate height, of a light colour, and strewed over with fragments of those invariable remarks of former population, broken pottery. The outer surface of the mounds made them appear as mere heaps of earth, long exposed to the atmosphere; but he was assured by several well acquainted with the true features of the place, that on digging into the mounds, a masonry of unburnt bricks was found, with layers of reed between them, as in the ruins at Akkerhoof and the mounds of Meklooba at Babylon. The extent of the semicircle formed by these heaps, appears to be nearly two miles. The area of the city, however, had but few mounds throughout its whole extent, and those were small and isolated; the space was chiefly covered with thick heath, sending forth, as in the days of Xenophon, a highly aromatic odour, which formed a cover for partridges, hares, and gazelles, of each of which the traveller saw considerable numbers. After traversing a space within the walls, strewed with fragments of burnt bricks and pottery, he came to the tomb of Selman Pauk. "This Selman Pauk[210]," says Mr. Buckingham, "was a Persian barber, who, from the fire-worship of his ancestors, became a convert to Islam, under the persuasive eloquence of the great prophet of Modain himself; and, after a life of fidelity to the cause he had embraced, was buried here in his native city of Modain. The memory of this beloved companion of the great head of their faith is held in great respect by all the Mahometans of the country; for, besides the annual feast of the barbers of Bagdad, who in the month of April visit his tomb as that of a patron saint, there are others who come to it on pilgrimage at all seasons of the year."
