Having viewed all the architectural chambers in those few crags of the plain; my companions led me to see the Diwàn, which only of all the Héjr monuments is in the mount Ethlib, in a passage beyond a white sand-drift in face of the kella. Only this Liwàn or Diwàn, ‘hall or council chamber,’ of all the hewn monuments at el-Héjr, (besides some few and obscure caverns,) is plainly not sepulchral. The Diwán alone is lofty and large, well hewn within, with cornice and pilasters, and dressed to the square and plummet, yet a little obliquely. The Diwán alone is an open chamber: the front is of excellent simplicity, a pair of pilasters to the width of the hewn chamber, open as the nomad tent. The architrave is fallen with the forepart of the flat ceiling. The hall, which is ten paces large and deep eleven, and high as half the depth; looks northward. In the passage, which is fifty paces long, the sun never shines, a wind breathes there continually, even in summer: this was a cool site to be chosen in a sultry country. Deep sand lies drifted in the Diwan floor: the Aarab digging under the walls for “gun-salt,” (the cavern is a noon shelter of the nomad flocks,) find no bones, neither is there any appearance of burials.
