of the buildings of this period were covered with elaborate plaster ornaments, and that a lavish use was made of colour in their decoration. Of the later Assyrian period several ruins of buildings believed to be palaces have been excavated, of which the large palace at Khorsabad, the old name of which was Hisir-Sargon, now a small village between 10 and 11 miles north-east of Nineveh, has been the most completely explored, and this consequently is the best adapted to explain the general plan of an Assyrian edifice. M. Botta, when French Consul at Mosul, and M. Victor Place conducted these explorations, and the following details are taken from their works. Like all other Assyrian palaces, this was reared on a huge artificial mound, the labour of forming which must have been enormous. The reason for the construction of these mounds is not far to seek. Just as the chiefs of a mountainous country choose the loftiest peaks for their castles, so in Assyria, which was a very flat country, the extra defensive strength of elevated buildings was clearly appreciated; and as these absolute monarchs ruled over a teeming population and had a very large number of slaves, and only had to direct their taskmasters to impress labour whenever they wanted it, no difficulty existed in forming elevated platforms for their palaces. These were frequently close to a river, and it is by no means improbable that this was turned into the excavation from which the earth for the mound was taken, and thus formed a lake or moat as an additional defence. A further reason for these terraces may be found in the fact that in a hot climate buildings erected some 20 or 30 ft. above the level of the plain catch the breezes much more quickly than lower edifices. In the case of Khorsabad the terrace was made of sun-dried bricks, about 15·7 in. square and 2 in. thick. These bricks were made of the most carefully prepared clay. The terrace was faced by a retaining wall of coursed masonry, nearly 10 ft. in thickness. On this terrace the palace was built, and it consisted of a series of open courts arranged unsymmetrically, surrounded by state or private apartments, storehouses, stables, &c. Great care seems to have been exercised in the accurate orientation of the building, but in rather a peculiar manner. Instead of any one façade of the building facing due north, the corners face exactly towards the four points of the compass. The courts were all entered by magnificent portals flanked by gigantic figures, and were approached by flights of steps. Fig. 32 is a plan of the palace of Khorsabad, which was placed close to the boundary of the city; in fact it was partly outside the city wall proper, though surrounded by a wall of its own. The grand south-east portals or propylæa were adorned with huge human-headed bulls and gigantic figures, and gave access to a large court, 315 ft. by 280 ft., on the east side of which are the stables and out-houses, and on the west side the metal stores.
