We should, of course, wish to give a clearer explanation of the object and use of the various parts of the building, but this is a difficult matter. We have very little information as to the usages of the cult connected with the temple. It is therefore of great importance that in Babylon we have not only one, but a series of four temples, in which the arrangement of the chambers is clearly repeated. From these we can conclude with certainty that for a temple the towered façade, the vestibule, the court, the cella with its postament in the shallow niche, were regarded as indispensable. It is not difficult to recognise the small side-chamber near the cella as the store-place for the various requirements of the cult. The chamber next the vestibule can be identified with some certainty as either a waiting-room or the porter’s lodge. The long narrow passages near the cella are remarkable; others exactly similar have been found in other temples. They would be well adapted to enclose the ramps or staircases that led to the flat roof, and some part of them may, in fact, have been used for that purpose. But it is by no means easy to understand why two such arrangements so completely alike as G 1, G 2, G 3 and O 3, G 4, G 5 should have been placed close together. I might provisionally suppose that these passages represent the remains of a more ancient and certainly an unknown type of ground-plan. The whole arrangement gives an impression that the original Babylonian house was essentially a four-sided walled enclosure, inside which opposite the entrance, separated from the enclosing wall by a narrow intermediate space, stood a detached house of one room. In course of its development other single chambers were added, which were built near the other sides of the enclosing wall. The intermediate space would make it possible to guard the main house from any danger from robbers who might break through the outer walls. But this, as we have said, is all hypothetical, and entirely depends on the result of further research.
