That part of the mound in this instance which projected between the walls was a square of about 650 ft. each way, raised about 30 ft. above the level of the plain, and protected on every side by a supporting wall cased with stone of very beautiful masonry (Woodcut No. 60). Behind this, and inside the city, was a somewhat lower mound, about 300 ft. in width and 1300 or 1400 ft. in length, on which were situated the great portals of the palace, together with the stables and offices, and, outside the walls of the palace properly so called, the hareem. All the principal apartments of the palace properly so called were revêted with sculptural slabs of alabaster, generally about 9 ft. in height, like those at Nimroud; these either represent the wars or the peaceful amusements of King Sargon, commemorate his magnificence, or express his religious feelings. The great portals that gave access to the palace of Khorsabad from the city were among the most magnificent of those yet discovered. The façade in which they stood presented a frontage of 330 ft., in which were three portals; the central one flanked by great human-headed bulls 19 ft. in height, and on each side two other bulls 15 ft. high, with a giant strangling a lion between them, as shown in the woodcut (No. 62), representing what still remained of them when uncovered by M. Botta, and now forming one of the principal ornaments of the British Museum. These portals were reached from the city by a flight of steps, now entirely destroyed, but which there can be little difficulty in restoring from what we find at Persepolis and elsewhere. [Illustration: 61. Plan of Palace at Khorsabad, as completely excavated by M. Place. The parts tinted were actually found. Those in outline are conjectural.] These portals led to the great outer court of the palace, measuring 315 ft. by 280 between the buttresses with which it was adorned all round. On the right hand were six or seven smaller courts surrounded by the stables and outhouses of the palace, which were approached by a ramp on the outside, at the head of which was a block of buildings containing the cellarage, and generally the stores of eatables. On the left hand of this court were the metal stores, each room having been appropriated to iron, copper, or other such materials, and behind them, outside the palace, was the hareem.[81] In the northern angle, a rather insignificant passage formed a means of communication between this great outer court and the next, which was 360 ft. long by 200 wide, and probably open to the country, at least in front of the great portals. On the inner side of this second court a magnificent portal opened into what appears to have been the residential portion of the palace, measuring nearly 300 by 500 ft. over all. [Illustration: 62.
