with a recessed diamond, within the diamond is a recessed square, within the square a second recessed diamond, in the centre of which is a rosette. In the western compartment two of the motives consist of squares sunk within one another, a third of a doubly sunk square containing a triply sunk rosette, while the fourth is obliterated. Finally high up in the east and west walls under the vault is placed a small niche whereof the arch springs from engaged colonnettes. No. 31 is connected with No. 32 by a door opposite to the door in the central court. The construction of the roof in No. 32 is different from any other example of roofing in the palace. It is divided into three compartments by four heavy transverse arches which spring at a height of 2·85 metres from the floor, level and are set forward twice from the face of the wall (Plate 31, Fig. 1). Between the arches small barrel vaults are stretched across the chamber from north to south. In the eastern compartment the north and south head walls are carried up to the height of the vault. Immediately below the spring of the vault there is a sunk band in the head walls decorated with three recessed circles or rosettes. In the central and western compartment the vault terminates against a semi-dome, set over the angles in one case horizontally, in the other (the western compartment) by means of small recessed squinches (compare the west end of the ḥaram). Below the semi-domes there are a couple of narrow fillets, and below the sunk band of the eastern compartment a single wide fillet. Below these, at the same level in all the compartments, the head wall is decorated with pairs of arched niches, the arches being supported by engaged colonnettes. The colonnettes have no bases; a narrow impost serves them as capital. The face of the arches is decorated in two of the compartments by fillets and in the third (the western) by a zigzag motive. Within each niche there is a spear-shaped ornament sunk in the wall. In the spandrel between the arches there lies a recessed rosette. At a height of ·35 metre above the springing point of the transverse arches the head wall is set very slightly forward, in imitation of the outset of an oversailing vault. The arches of the doors rise higher than the level of this outset, which is lifted in a rectangular label over them. The barrel vaults between the transverse arches are variously treated. The eastern vault is divided into sections by three short transverse arches, each of which is decorated by a square sunk motive. The central vault has the same number of short transverse arches, but these are undecorated. The western vault is provided with a transverse arch against the semi-dome at either end, while the remainder of its length is decorated with stucco ridges. A pair of niches, smaller than those upon the side walls, is placed in the east and in the west wall under the transverse arches, but the spear-shaped ornament and the recessed
