Two hours’ ride to the south-east of Mudjḍah is the ruined caravanserai which the Arabs call ‘Aṭshân, the Thirsty--the name is well deserved, for there is no water nearer than the Hindiyyeh.[41] It is not exactly oriented, but faces approximately north (Plate 46, Fig. 2). It is built of brick tiles varying from ·31 × ·31 × ·7 metre to ·32 × ·32 × ·8 metre and sometimes as large as ·34 metre square. The walls enclose an area 29 metres square; they are 1·80 metres thick, and are strengthened at the angles by round towers, 4·10 metres in diameter, projecting 1·90 metres from the face of the walls, as well as by smaller towers 2·75 metres in diameter which are placed in the centre of the east, west, and south walls. The small towers have the same projection as the angle towers. In the centre of the north wall is the gate, which is pierced through a double tower having a projection of 3·10 metres from the face of the wall. The gate towers are preserved up to a considerably greater height than the other towers (Plate 48, Fig. 2), but the systematic levelling of the walls and towers is probably due to brick-robbers, and there is nothing to indicate their original height. Even the gate-house towers have been higher than they are at present (Plate 49, Fig. 1). The west wall has fallen, carrying with it the south-west tower and all the constructions in the interior which ran along this side. The whole edifice looks as if it had been terribly shaken by earthquake; great cracks have sprung open in the solid masonry; the north-east tower leans outward and is on the point of falling.
