In attempting a reconstruction of the Ukhaiḍir façade (Plate 85) I have sought some guidance from the representation of a Sasanian fortress which is to be seen upon a silver dish, now in the possession of the Kais. Archäol. Kommission of St. Petersburg[336] (Plate 86, Fig. 2). It has been assigned to the beginning of the Sasanian period. The façade depicted bears some interesting analogies to that of Ukhaiḍir. It is divided into two stories. In the lower story the lower zone consists of eight arched niches, the arches borne on tall engaged columns without capitals. The archivolts are decorated with three fillets and a small oval motive is placed in the spandrels. Above the arches there is a cornice composed of two simple horizontal mouldings with a band of spirals between them. I surmise that these spirals, which seem to be singularly out of place in a monumental façade, were put in to fill up the space and have no warrant in any actual building. The gateway occupies the centre of this zone. A wide archway, set in a rectangular frame, covers two narrow arched doors. Within the semicircle of the embracing arch there is a shallow calotte decorated with broken concentric rings. The archivolt is outlined by a moulding which is carried up continuously round the rectangular frame. Within this frame a horizontal moulding is laid above the arch. This scheme of archivolt and rectangular frame with a continuous moulding is common in Syria and Mesopotamia.[337] The crowning member of the portal breaks the line of the cornice. It consists of a frieze carved in relief with a human (or divine?) head and bust, and a cornice bearing a row of cusps. The upper zone of the lower story is less easy to describe in terms of architecture. There is a frieze (or dwarf order?) decorated with four groups of six flutings or engaged colonnettes and five groups of four circles, each circle containing a quatrefoil. The cornice is composed of two bands, the first decorated with alternate circles and rhomboids, the second with diagonal brickwork. A projecting hourd is placed at either end of the building, and between the hourds the top of the wall is battlemented. These crenellations form a parapet to the gangway which runs along the base of the second tower-like story. Upon the gangway stand eight figures, seven of whom are blowing trumpets. Behind them the wall is plain, but the upper part is decorated first with a band of half-florettes, then with a row of arched niches, each niche being set within a rectangular frame, and finally with a band of diagonal brickwork. The summit of the wall is battlemented and a wooden hourd projects from either side. The lower zone of the lower story corresponds very fairly with the lowest zone at Ukhaiḍir. The schematized horizontal bands of the second zone bear little or no relation to real architecture, but the upper story is set back, as at Ukhaiḍir, and the battlemented parapet of the gangway is a very probable solution for the
