We have, on the contrary, followed the wall that turns to the east up to the end (Fig. [107]). It has a length of about 250 metres, guarded by towers placed closely together, and a door in each mesopyrgion. It represents therefore a site admirably adapted for sorties. The gateway embrasures lie exclusively on the north. At the east the wall turns to the south and joins with one leading from the Procession Street that has not yet been examined in detail. All these eastern walls have been destroyed from the point where they were cut through by the Persian advanced wall down to a great depth, so that it is only with difficulty that a few brick courses could be found above water-level. Above the ruins there lies silt which was evidently formed by water passing over it at some time. On this and immediately below the present level there are remains of later houses either of mud brick or of burnt brick. A little above the ruins, in the line of the northern wall, there was an anthropoid clay coffin (see Fig. [200]), the face represented with an Egyptian beard. I believe that the Euphrates, as in Persian times it worked its channel eastwards, thus placing the Kasr on the right bank, first ruined these eastern walls and then formed a muddy peninsula with their ruins, while the actual river flowed still farther east. This is, however, not yet proved.

The position of the double walls that flanked the Procession Street is described in the inscription on a great cylinder that we found on the eastern slope of the Amran hill. It had been used there for some technical purpose, and is much worn. The part that refers to our site runs thus: “At that time I bethought myself to strengthen the stronghold of Babylon. 360 ells of the land the sides (or of the sides) of Nimitti-Bel, the šalḫû of Babylon, I built as a protection from the banks of the Euphrates to the left threshold of the Ištar Gate two mighty walls of asphalt and burnt brick for a dûru like a mountain. Between them I erected a terrace of burnt brick, and upon it a great castle (?) as a dwelling-place of my kingdom. Of asphalt and burnt brick I built high, joined (it) with the palace, which (lay) within the city, and caused the dwelling of my lordship to be glorious. Besides, from the right threshold of the Ištar Gate to the lower turru of Nimitti-Bel in the east 360 ells broadside, (measured) from Nimitti-Bel, for protection, a mighty dûru of asphalt and burnt brick I built mountain high. The stronghold I strengthened with skill. The city of Babylon I protected” (trans. by Weissbach).

As we have seen, the Ishtar Gate had a central door and two side ones. These last are evidently intended for the left- and right-hand thresholds of the Ishtar Gate. The distance from the wall at the threshold to the north side of the bastion on the eastern wall is 192 metres, and on the western wall 196 metres. This gives as measure for Nebuchadnezzar’s ells .533 or .544 metres. These measurements must, however, be taken again more accurately on the completion of the excavations. The length of 490 ells, which is quoted for the same area in the great Steinplatten inscription, includes the northern extension of the wall, to which we shall soon turn.

XXVIII
THE NORTHERN CITADEL

The Northern Citadel, as we call the part of the Kasr north of the square 6, is still in process of excavation. Various results have already been gained from it which admit of description, though with some reservations. The work has been on the eastern part, the prolongation of the Procession Street and its termination at the north.

The site, so far as it has been opened up, is on the whole a repetition of what we have seen in the previous chapter. Both the measurements and directions of the walls are entirely analogous with those of the earlier ones. Here again are the two walls flanking the Procession Street, ending in bastions, and then turning off east and west.

Here also we have followed the eastern wall to the end, where it turns southwards until it joins the corner of the earlier wall. There is some indication that the architect intended at least a continuation of this plan towards the east, and in fact at the east end of the inner and older wall there was a groove in the brickwork that points to such an intention. We, however, have not found the slightest trace of any such wall, although we have carefully searched for it both close to the angle of the wall, and also farther east. Nothing has been found in the trenches made for this purpose except the ruins of later houses above and mud with a complete absence of buildings below. Thus from ancient days till its downfall this site remained without any prolongation to the east.
