With respect to the shrine which was emplaced upon the topmost, or silver stage, little is definitely known. It appears to have been of brick; and we may perhaps conclude from the analogy of the old Chaldaean shrines at the summits of towers, as well as from that of the Belus shrine at Babylon, that it was richly ornamented both within and without; but it is impossible to state anything as to the exact character of the ornamentation. The tower is to be regarded as fronting to the north-east, the coolest side and that least exposed to the sun’s rays from the time that they become oppressive in Babylonia. On this side was the ascent, which consisted probably of abroad staircase extending along the whole front of the building. The side platforms (those towards the south-east and north-west)--at any rate of the first and second stages, probably of all--were occupied by a series of chambers abutting upon the perpendicular wall, as the priests’ chambers of Solomon’s temple abutted upon the side walls of that building. In these were doubtless lodged the priests and other attendants upon the temple service. The side chambers seem sometimes to have communicated with vaulted apartments within the solid mass of the structure, like those of which we hear in the structure supporting the “hanging gardens.” It is possible that there may have been internal stair-cases, connecting the vaulted apartments of one stage with those of another; but the ruin has not yet been sufficiently explored for us to determine whether or not there was such communication. The great Tower is thought to have been approached through a vestibule of considerable size. Towards the north-east the existing ruin is prolonged in an irregular manner and it is imagined that this prolongation marks the site of a vestibule or propylaeum, originally distinct from the tower, but now, through the crumbling down of both buildings, confused with its ruins. As no scientific examination has been made of this part of the mound, the above supposition can only be regarded as a conjecture. Possibly the excrescence does not so much mark a vestibule as a second shrine, like that which is said to have existed at the foot of the Belus Tower at Babylon. Till, however, additional researches have been made, it is in vain to think of restoring the plan or elevation of this part of the temple.
