There is a slight error here in Dr. Reuther’s reconstruction, an error to which he himself called my attention. He has placed only one small niche in the upper register instead of three. The side niches can be seen in Plate 27. He suggests that in the middle of the façade one or more of these small niches must have contained windows in order to give additional light to room 101, since it was from room 101 that most of the light in the great hall was derived. Beyond the arcading on either side of the façade the wall was finished by a solid pier, the surface of which was broken by three projecting horizontal bars. The cornices are not preserved, but, as I shall show later, they cannot have been very important. The decoration of the façade ends on the level of the second floor and forms a narrow balcony a little over 1 metre wide which runs along the face of the building. The wall of the second floor is recessed a few centimetres to give additional width to this balcony. On to it open the doors of Nos. 123 and 127. These doors are not placed symmetrically with respect to the façade; the west door is nearer the centre than is the east door. The plain wall is carried up to the top of the door arches; above that level there is a band of shallow arched niches which appear to have been divided from one another by engaged columns, probably carrying an architrave, like the niches on the summit of the outer north wall of the palace. To return to the central court. On the east side there is a doorway in the third intercolumniation from the south end (Plate 26, Fig. 2). It leads into corridor 28. The arch of this door is set back from the jambs, but the upper part is ruined. The corresponding door on the west side has disappeared, together with most of the south-west end of the wall. On the east side the arcading is not carried into the angle of the court. The southernmost archivolt ends against a quarter-column, beyond which space is provided for the entrance of a stair which leads down to a vaulted chamber below the level of the ground (Plate 28, Fig. 1). Above this entrance there is a fluted semi-dome finished by a fillet (Plate 28, Fig. 2). The semi-dome is set horizontally over the angles of the niche in the accustomed manner. The actual entrance to the stair is covered not by an arch but by a masonry lintel (compare the door between 20 and 21).
