In so far as it has been explored, the lower storey forms a perfect square, 272 feet each way. Above this are six storeys, each 42 feet less in horizontal dimensions. These are not placed concentrically on those below them, but at a distance of only 12 feet from the south-eastern edge, and consequently 30 feet from the N.W., and 21 feet from the two other sides. [Illustration: 50. Diagram Elevation of Birs Nimroud. Scale 100 ft. to 4 in.] [Illustration: 51. Diagram Plan of Birs Nimroud. Scale 100 ft. to 1 in.] The height of the three upper storeys seems to have been ascertained with sufficient correctness to be 15 feet each, or 45 feet together. Unfortunately no excavation was undertaken to ascertain the height of the lowest and most important storey. Sir Henry Rawlinson assumes it at 26; and I have ventured to make it 45, from the analogy of the tomb of Cyrus and the temple at Mugheyr. The height of the two intermediate storeys, instead of being 22 feet 6 inches, as we might expect, was 26, which seems to have resulted from some adjustment due to the chambers which ranged along their walls on two sides. The exact form and dimensions of these chambers were not ascertained, which is very much to be regretted, as they seem the counterpart of those which surrounded Solomon’s Temple and the Viharas in India, and are consequently among the most interesting peculiarities of this building. No attempt was made to investigate the design of the upper storey, though it does not seem that it would be difficult to do so, as fragments of its vaulted roof are strewed about the base of the tower-like fragment that remains, from which a restoration might be effected by any one accustomed to such investigations.[71] What we do know is that it was the cella or sanctuary of the temple.[72] There probably also was a shrine on the third platform. This temple, as we know from the decipherment of the cylinders which were found on its angles, was dedicated to the seven planets or heavenly spheres, and we find it consequently adorned with the colours of each. The lower, which was also richly panelled, was black, the colour of Saturn; the next, orange, the colour of Jupiter; the third, red, emblematic of Mars; the fourth, yellow, belonging to the sun; the fifth and sixth, green and blue respectively, as dedicated to Venus and Mercury; and the upper probably white, that being the colour belonging to the Moon, whose place in the Chaldean system would be uppermost. Access to each of these storeys was obtained by stairs, probably arranged as shown in the plan; these have crumbled away or been removed, though probably traces of them might still have been found if the explorations had been more complete.
