Fifteen fragments of dolerite with inscriptions belong to stelae of the same kind as one that was found by brick robbers shortly before the beginning of our excavations, in the north-east corner of the Principal Citadel. It is an upright semi-cylindrical block inscribed on both sides, on which Nabonidus reports in detail on his endowment of temples in Babylon and other places (see Scheil, “Inscription de Nabonide,” in the _Recueil de travaux rel. à la philologie_, etc., xviii. p. 15). A block of dolerite which formed part of a thick large stela was found in _r_ 9 of the Kasr plan. It contains in Neo-Babylonian writing a duplicate of the famous inscription which Darius Hystaspes (521–485) engraved on the rocks of Bagistana in Persian, Susian, and Babylonian. The numerous fragments of building cylinders which have been found on the Kasr, naturally refer principally to the building of the palace, the Ishtar Gate, and the fortification walls. The greater number are Nebuchadnezzar’s, but there are a few of Sardanapalus, Nabopolassar, Nabonidus, and Neriglissar. A number that were found actually in the Principal Citadel are of buildings outside the Kasr, such as Etemenanki, and of buildings outside Babylon. Thus we have an inscription of Nabonidus of E-ḫul-ḫul in Haran, one of E-bar-ra in Sippara, and one of Nebuchadnezzar from E-ul-la in Sippara, and also an E-an-na of Sardanapalus and others. It appears therefore that such documents were systematically collected and preserved in the Principal Citadel. Any one who compares the comparatively small area that is excavated with the extent of that which is yet untouched, and realises how much has already been found, will see how much yet remains to be done and acquired in the Principal Citadel, apart from the gain to science that would ensue from laying open the palace buildings. The palace did not extend quite as far as the fortification wall on the north. The foundations of the front consist of excellent brickwork laid in asphalt and reeds, while in the foundations behind broken brick laid in lime mortar is employed throughout.
