Mshattâ lies a few hours to the west of Kharâneh (Plate 81).[259] It is the best known of the Syrian ḥîrahs, and its magnificent carved façade is now in the Kaiser Friedrich Museum. All that concerns me here, however, is its place in the architectural group of which Ukhaiḍir is the eastern representative. It was perhaps built by Yazîd II,[260] and it was left unfinished at his death. It may therefore be a little later than Kharâneh, for Yazîd died in A.D. 724. As at Ṭûbah and Ukhaiḍir, the materials used in it are brick and stone. It is surrounded by a wall set with towers, of which, as at Ukhaiḍir, more than the half-circle projects. The towers on either side of the main gateway are octagonal. Of the buildings immediately within the gate we have nothing but the ground-plan. Roughly speaking they correspond to the three-storied block at Ukhaiḍir, and as Dr. Herzfeld has pointed out,[261] a further correspondence lies in the fact that the oblong court to the right of the gate-house group, with a niche in the qiblah wall, was probably a mosque. The mosque at Ukhaiḍir occupies much the same position with regard to the gate, but since the orientation of the two buildings is different, the qiblah niche at Mshattâ is hollowed out of the main outer wall, while the niche at Ukhaiḍir is hollowed out of an opposite wall. (It must be noted that the big mosque in the palace of Balkuwârâ occupies the same position relatively to the gate.) The conclusion which Dr. Herzfeld reaches, namely that neither palace was a copy of the other, but that both were reproductions by different hands of the same general scheme, is borne out in all other particulars. Beyond the gate-house block lies the central court; beyond the court the hall of audience. At Mshattâ, where the lîwân was unknown, its place was taken by an aisled hall on a basilical plan. Instead of the simple apse there is a trifoliate chamber covered by a dome. The most renowned example of the trifoliate apse is in the church at Bethlehem. The learned disagree as to whether that apse was built by Constantine or by Justinian, but in either case it was earlier than Mshattâ. For the rest, the trifoliate or quadrifoliate chamber covered by a dome is a familiar Hellenistic motive which occurs frequently in palaces and in the baptisteries of early Christian churches. At Ukhaiḍir we have, in the same position as the trifoliate chamber, the quadrangular room No. 30. The throne-room, if I may so term it, at Mshattâ bears comparison with the throne-room at Qṣair ‘Amrah, where two small apsed rooms correspond to the apsed side niches. On either side of the ceremonial chambers of Mshattâ lies a bait, the unit, now complete, which was foreshadowed at Kharâneh and at Qasṭal. Such is the arrangement of the central part of the palace. The two wings (to return to Mas’ûdi’s definition) were never built. Schultz’s ingenious reconstruction gives in each wing a row of baits,
