I ordered tunnels to be carried along the basement wall in both directions, hoping to reach some doorway or entrance, but it was found to consist of solid masonry, extending nearly the whole length of the mound. Its height was exactly twenty feet, which, singularly enough, coincides with that assigned by Xenophon to the stone basement of the wall of the city (Larissa).[45] The stones in this structure were carefully fitted together, though not united with mortar, unless the earth which filled the crevices was the remains of mud, used, as it still is in the country, as a cement. They were bevelled with a slanting bevel, and in the face of the wall were eight recesses or false windows, four on each side of a square projecting block between gradines.

The basement, of which this wall proved to be only one face, was not excavated on the northern and eastern side until a later period, but I will describe all the discoveries connected with this singular building at once. The northern side was of the same height as, and resembled in its masonry, the western. It had a semicircular hollow projection in the centre, sixteen feet in diameter, on the east side of which were two recesses, and on the west four, so that the two ends of the wall were not uniform. That part of the basement against which the great artificial mound or platform abutted, and which was consequently concealed by it, that is, the eastern and southern sides, was of simple stone masonry without recesses or ornament. The upper part of the edifice, resting on the stone substructure, consisted of compact masonry of burnt bricks, which were mostly inscribed with the name of the founder of the centre palace (the obelisk king), the inscription being in many instances turned outwards.

It was thus evident that the high conical mound forming the north-west corner of the ruins of Nimroud, was the remains of a square tower, and not of a pyramid, as had previously been conjectured. The lower part, built of solid stone masonry, had withstood the wreck of ages, but the upper walls of burnt brick, and the inner mass of sun-dried brick which they encased, falling outwards, and having been subsequently covered with earth and vegetation, the ruin had taken the pyramidal form that loose materials falling in this manner would naturally assume.

It is very probable that this ruin represents the tomb of Sardanapalus, which, according to the Greek geographers, stood at the entrance of the city of Nineveh. It will hereafter be seen that it is not impossible the builder of the north-west palace of Nimroud was a king of that name, although it is doubtful whether he can be identified with the historical Sardanapalus. Subsequent discoveries proved that he must himself have raised the stone substructure, although his son, whose name is found upon the bricks, completed the building. It was, of course, natural to conjecture that some traces of the chamber in which the royal remains were deposited, were to be found in the ruin, and I determined to examine it as fully as I was able. Having first ascertained the exact centre of the western stone basement, I there forced a passage through it. This was a work of some difficulty, as the wall was 8 ft. 9 in. thick, and strongly built of large rough stones. Having, however, accomplished this step, I carried a tunnel completely through the mound, at its very base, and on a level with the natural rock, until we reached the opposite basement wall, at a distance of 150 feet. Nothing having been discovered by this cutting, I directed a second to be made at right angles to it, crossing it exactly in the centre, and reaching from the northern to the southern basement; but without any discovery.

The next cutting was made in the centre of the mound, on a line with the top of the stone basement wall, which was also the level of the platform of the north-west palace. The workmen soon came to a narrow gallery, about 100 feet long, 12 feet high, and 6 feet broad, which was blocked up at the two ends without any entrance being left into it. It was vaulted with sun-dried bricks, a further proof of the use of the arch at a very early period, and the vault had in one or two places fallen in. No remains whatever were found in it, neither fragments of sculpture or inscription, nor any smaller relic. There were, however, undoubted traces of its having once been broken into on the western side, by digging into the face of the mound after the edifice was in ruins, and consequently, therefore, long after the fall of the Assyrian empire. The remains which it may have contained, probably the embalmed body of the king, with vessels of precious metals and other objects of value buried with it, had been carried off by those who had opened the tomb at some remote period, in search of treasure. They must have had some clue to the precise position of the chamber, or how could they have dug into the mound exactly at the right spot? Had this depositary of the dead escaped earlier violation, who can tell with what valuable and important relics of Assyrian art or Assyrian history it might have furnished us? I explored, with feelings of great disappointment, the empty chamber, and then opened other tunnels, without further results, in the upper parts of the mound.

It was evident that the long gallery or chamber I have described was the place of deposit for the body of the king, if this were really his tomb. The tunnels and cuttings in other parts of the mound only exposed a compact and solid mass of sun-dried brick masonry. I much doubt, for many reasons, whether any sepulchre exists in the rock beneath the foundations of the tower, though, of course, it is not impossible that such may be the case.[46]

From the present state of the ruin it is difficult to conjecture the exact original form and height of this edifice. There can be no doubt that it was a vast square tower, and it is not improbable that it may have terminated in a series of three or more gradines, like the obelisk of black marble from the centre palace now in the British Museum. Like the palaces, too, it was probably painted on the outside with various mythic figures and devices, and its summit may have been crowned by an altar, on which the Assyrian king offered up his great sacrifices, or on which was fed the ever-burning sacred fire. But I will defer any further remarks upon this subject until I treat of the architecture of the Assyrians.

As the ruin is 140 feet high, the building could scarcely have been much less than 200, whilst the immense mass of rubbish surrounding and covering the base shows that it might have been considerably more.

During the two months in which the greater part of the discoveries described in this chapter were made, I was occupied almost entirely with the excavations, my time being spent between Nimroud and Kouyunjik.

Wishing to visit Baasheikhah, Khorsabad, and other ruins at the foot of the range of low hills of the Gebel Makloub, I left Nimroud on the 26th of November with Hormuzd and the Bairakdar. Four hours’ ride brought us to some small artificial mounds near the village of Lak, about three miles to the east of the high road to Mosul. Here we found a party of workmen excavating under one of the Christian superintendents. Nothing had been discovered except fragments of pottery and a few bricks bearing the name of the Kouyunjik king. As the ruins, from their size, did not promise other results, I sent the men back to Mosul. We reached Khorsabad after riding for nearly eight hours over a rich plain, capable of very high cultivation, though wanting in water, and still well stocked with villages, between which we startled large flocks of gazelles and bustards. I had sent one of my overseers there some days before to uncover the platform to the west of the principal edifice, a part of the building I was desirous of examining. Whilst clearing away the rubbish, he had discovered two bas-reliefs sculptured in black stone. They represented a hunting scene, and were executed with much truth and spirit. They belonged to a small building, believed to be a temple, entirely constructed of black marble, and attached to the palace. It stood upon a platform 165 feet in length and 100 in width, raised about six feet above the level of the flooring of the chambers, and ascended from the main building by a flight of broad steps. This platform, or stylobate, is remarkable for a cornice in grey limestone carried round the four sides,—one of the few remains of exterior decoration in Assyrian architecture, with which we are acquainted. It is carefully built of separate stones, placed side by side, each forming part of the section of the cornice. Mr. Fergusson observes,[47] with reference to it, “at first sight it seems almost purely Egyptian; but there are peculiarities in which it differs from any found in that country, especially in the curve being continued beyond the vertical tangent, and the consequent projection of the torus giving a second shadow. Whether the effect of this would be pleasant or not in a cornice placed so high that we must look up to it, is not quite clear; but below the level of the eye, or slightly above it, the result must have been more pleasing than any form found in Egypt, and where sculpture is not added might be used with effect anywhere.”
