Not far from the Southern Citadel the trench brought to light two walls, of which the thicker one on the west replaced the older and narrower one (ÄG) (Fig. [81]); they cannot therefore both have been standing at the same time. In the upper courses of the thicker wall (GI, cf. fig. 82) there is a large number of bricks placed closely together, all of which bear the following inscription (Fig. [83]): “Nebuchadnezzar, King of Babylon, the exalted prince, the nourisher of Esagila and Ezida, son of Nabopolassar, King of Babylon, am I. Since Nabopolassar, my father, my begetter, made Imgur-Bel the great Dûr of Babylon, I, the fervent suppliant, worshipper of the Lord of lords, dug its fosses and raised its banks of asphalt and baked bricks mountain high. Marduk, great Lord, behold with contentment the costly work of my hands, mayest thou be my helper, my standbye! Length of days send as a gift” (trans. by Delitzsch). Here then we have the slope, the escarpment of the most celebrated and earliest fortification of Babylon that bore the name of Imgur-Bel, “grace of Bel.” Nebuchadnezzar explicitly refers to an Imgur-Bel that was built by Nabopolassar. This Imgur-Bel of Nabopolassar no longer exists, with the exception possibly of some fragmentary remains, but we have a foundation record of Nabopolassar that concerns it. The cylinder, which is small and in excellent condition, was found in the Southern Citadel (u 22) close to the Citadel wall, in rubbish south of the Vaulted Building, and therefore not in situ. The text on it runs: “Nabopolassar, King of Babylon, the chosen of Nabu and Marduk, am I. Imgur-Bel, the great Dûr of Babylon, which before me had become weak and fallen, I founded in the primeval abyss. I built it anew with the help of the hosts, the levies of my land. I caused Babylon to be enclosed by it towards the four winds of heaven. I set up its top as in the former time. Dûr, speak to Marduk my Lord on my behalf” (trans. by Delitzsch). From this it appears that the Imgur-Bel of Nabopolassar formed a quadrilateral, closed on all sides, and that it was constructed of burnt brick, as the deep foundations would be neither necessary nor possible for crude brick. The old part of the eastern city wall may thus have formed a portion of the Imgur-Bel of Nabopolassar. The wall of the moat unites on the south with the Citadel wall by a grooved expansion joint, but the groove is cut in the moat wall, which originally extended farther to the south and is older than the Citadel wall at this point. In the north it turns in an easterly direction, and the corner is marked by an immense bastion. On the outer side in the angle of the bastion there are two well shafts hewn out of the brickwork, the openings closed with a grating of pierced stone slabs.
Farther to the north the wall is still buried under the rubbish as far as its eastern termination, where it starts again from another great outstanding bastion to the north of the Ishtar Gate, and there rests against the exactly similarly constructed bastion of the older moat wall.
This older moat wall runs on almost the same lines as the later one, but somewhat within it. Like the latter it is laid with asphalt and reeds, but has smaller unstamped bricks, measuring 32 × 32 centimetres. In the trench near the Persian building we found it at a great depth, and excavated the northern portion of it with the corner bastion, in the angle of which is a well, this time a walled one. A tablet that referred to the construction of this well was found close by. The wall rests on a broad foundation banquette, and stretches in an easterly direction, ending with a substantial tower at the Arachtu wall of Nabopolassar, and reappearing at the Ishtar Gate with the above-mentioned outstanding bastion. Here we can recognise a later addition, a raising of the wall, for the strengthening of which powerful beams are jointed in. The lower part has a slight batter, and was later washed over with asphalt, like the walls of Nabopolassar’s palace, which we have already described.
In the well-built but not deeply-founded cross wall, between the bastion and the Ishtar Gate, a broad doorway with a flight of steps led down westward from the level of the earlier Procession Street.
