The donjon or body is defended by an enceinte, opening northwards upon a large yard, where, doubtless, the garrison mustered, and whence a flight of steps leads to the wicket. The inside of the works shows the roofless party-walls still standing; and the ground is scattered over with the remains of many different races: there are drums of columns and fragments of marble pillars, but no sign of an inscription. Even in the upper ramparts two epochs are distinctly traceable, the mediæval and the modern. The lower ashlar, mostly yellow grit, is cut and carefully cemented; the upper part is generally of rough dry stone, the plutonic formations of the islet heaped up with scanty care. The embrasures are framed with decaying palm-trunks; the loop-holes belong partly to the age of archery; and nothing can be ruder than the battlements placed close together, as if to be manned by bowmen, while in not a few places there are the remains of matting between the courses. At the highest part we found another carefully cemented Sehrij, or underground cistern, with two sharp-topped arches divided by a tall column, Saracenic certainly and not Doric:[EN#125] above it a circular aperture, arched round with the finest bricks, serves to lighten the superstructure. It communicates to the north with a Hammám, whose plan is easily traced by the double flues and earthenware tubes, well made and mortared together. Here we found inscribed on the plaster, "Arona Linant 22 Mars 1846." The southern knob of the islet supports similar but inferior constructions, still more ruinous withal: its quarry is on the lower slopes, and its granitic base has also been scarped seawards. Two stout walls, twelve feet thick below and six above, crossing the length of the rock from north to south, here meet in a Burj which shows signs of fine tiles on an upper floor; whilst a third wall forms a southern spine bisecting the tail of the "Jezírat." The castle is much more dilapidated than when sketched by Ruppell, the first Frank who visited El-'Akabah, in 1826. His illustration (p. 214) of Ruinen auf der Insel Emrag shows a single compact building in good preservation, the towers being round, when all are square; and it is garnished with the impossible foreground and background of his epoch; the former, enlivened with a Noah's-Ark camel, being placed quite close, when it is distant some ten miles. In the German naturalist's time, the now desolate island was occupied by die Emradi, a tribe which he suspected to be Jewish, and of which he told the queerest tales: I presume they are the 'Imrám-Huwaytát of El-Hakl and the Hismá. Wellsted's short description (II. ix) is still correct as in 1838.
