Round this older Kisu, which exactly follows the outer lines of the temple with all its projections, there runs a later one, which has only large tower projections in some places. It is built with Nebuchadnezzar’s bricks, and its foundations are not so deep as those of its predecessor. Towards the south there appear to be remains of a third Kisu of still shallower foundation. In the south behind the temple, as low down as the ancient Kisu, are buildings of mud brick which we have not sought further. They show that the Citadel square was formerly occupied by buildings of a private character. To whom the two upper pavements which still remain in the entrance doorway may be ascribed cannot be stated with certainty. In this case we cannot place much reliance on the Nebuchadnezzar stamps. On the upper pavement stood an entirely unimportant construction of Nabonidus bricks. This building in later years was demolished and levelled above the upper pavement, and on it was erected a building of mud brick on the lines, however, of the ancient temple. So little of it now remains that it is impossible to make out its purpose with any certainty. In order to secure more strength for the building, wooden clamps were inserted about half-way between the bottom of the foundations and the main flooring, which reached from the outer walls to those opposite. We found the holes left by them in the walls of the north-east room, and in chamber W 2. At about each 8th course there is a thick layer of reeds laid crossways over each other, which have now rotted to a white powder. They were certainly intended in some way to strengthen the walls, but it is now difficult to estimate the length of time for which they served this purpose. The angles of the walls at the gates were secured by the insertion of pieces of wood washed over with tar. A plank of wood, the height of a brick course, lay in the jamb, and another, one course higher on each side, thus forming a frame, which probably also served as an attachment for the door or door casing.
