[Footnote 108: See Fig. 15; its position is indicated in the southern doorway (2) of the outer gate-house. This was the first part of the gateway to be discovered, as it stands higher than the rest.]
[Footnote 110: The same process was employed for the Lion Frieze to the north of the gateway; see below, p. 59.]
[Footnote 111: See Fig. 18, B, B. The fortified areas to the west of the roadway, which Nebuchadnezzar built out as direct extensions of the Southern Citadel upon its north side, are still in course of excavation. They have been christened the "Principal Citadel" and the "Northern Citadel" of the Ḳaṣr. The most interesting construction yet recovered there is a broad canal (Fig. 18, J), to the north of the palace-area of the Principal Citadel; this was evidently left uncovered, and it must have drawn its water-supply from the Euphrates through grated openings in the western wall. To the east of the roadway lines of defence were thrown out corresponding to those of the two later citadels. The foundations of their eastern wall, approximately parallel to the roadway, have been uncovered; but the whole of this area was destroyed by the Euphrates when it changed its course, and only the main fortification-walls can now be traced below the deposit of silt.]
[Footnote 112: The red enamel has decomposed and is now green. All the lions, like the enamelled beasts of the Ishtar Gate, were found in fragments.]
[Footnote 113: Compare the plan on p. 30, Fig. 6, where the Procession Street, in its course past the Citadel, is lettered G.]
[Footnote 114: Cf. Koldewey, "Die Pflastersteine von Aiburschabu in Babylon," pp. 4 ff. The limestone is termed _shadâ,_ or "mountain-stone," and Koldewey suggests that it was quarried in the neighbourhood of Hit on the Euphrates. The quarries from which the _turmina-banda,_ or breccia, was obtained have not yet been identified.]
[Footnote 115: The course of the Procession Street may be followed in the plan on p. 83, Fig. 31; it is there marked A. The Temple of Ishtar of Akkad is lettered H.]
[Footnote 117: Fig. 30, E, F; compare also Fig. 27 on p. 74, with the same lettering.]
