In the gateway the three upper floorings lie superimposed and separated from each other by layers of earth. They are very instructive and show that they pertain to the last three raisings of the temple-level. That the temple was raised twice previously we learn from the cella. Under each pavement at the gate there is a channel which carried off the rain-water from the building, and on each side of the entrance, also under the pavement, is one of those remarkable structures formed of six bricks placed together which we found in connection with almost every doorway of any importance in the temples. One of these was empty, but in the eastern one was deposited a bird in earthenware, and with it a fragment of pottery with an almost illegible inscription. Such deposits may probably be termed offerings, and every one of these small caskets which is now empty certainly contained gifts which in course of time have perished and disappeared. The exact significance attached to them by the Babylonians we do not know; the inscriptions found on some of the clay figures on other sites do not make this clear. The entrance was fitted with double doors. The base of the doorposts stood in a bronze ferrule (Fig. 39), and turned in stone sockets of considerable dimensions. The brick cavities in which these sockets were inserted are well preserved, the stone sockets themselves have disappeared, as in most other cases. The two blocks of brickwork by which the old pivot sockets were partially covered were in some way which cannot now be clearly recognised used as foundations for the stone sockets of the later, higher pavement. The door could be very strongly barricaded, apart from the bolts which we may safely take for granted, by a beam that was propped against it from the inside. For the admission of this beam there was a slight depression in the pavement and also a stone which rose slightly above its level exactly as at the Urash Gate, and at the Citadel gateway at Sendjirli. The usual method of fastening was undoubtedly by beams which could be drawn out of the wall, as we shall see them in the ancient gate of the Southern Citadel. The prop was intended merely to strengthen the fastenings in troubled times and enable the priests of Emach to defend their sanctuary as a stronghold. The towers and parapets of the external walls may also have helped in this case. [Illustration: FIG. 40.—Court in Ninmach Temple. ]
