Another Assyrian palace, of which considerable remains still exist, is that of Esarhaddon, commonly known as the South-west Palace at Nimroud. Like the others, this too has been destroyed by fire, and the only part that remains sufficiently entire to be described is the entrance or southern hall. Its general dimensions are 165 ft. in length by 62 ft. in width, and it consequently is the largest hall yet found in Assyria. The architects, however, either from constructive necessities or for purposes of state, divided it down the centre by a wall supporting dwarf columns,[85] forming a central gallery, to which access was had by bridge galleries at both ends, a mode of arrangement capable of great variety and picturesqueness of effect, and of which there is little doubt that the builders availed themselves to the fullest extent. This led into a courtyard of considerable dimensions, surrounded by apartments, but they are all too much destroyed by fire to be intelligible. [Illustration: 69. Hall of South-West Palace. Scale 100 ft. to 1 in.] Another great palace, built, as appears from the inscriptions, by a son of Esarhaddon, has been discovered nearly in the centre of the mound at Koyunjik. Its terrace-wall has been explored for nearly 300 ft. in two directions from the angle near which the principal entrance is placed. This is on a level 20 ft. lower than the palace itself, which is reached by an inclined passage nearly 200 ft. in length, adorned with sculpture on both sides. The palace itself, as far as its exploration has been carried, appears similar in its arrangements to those already described; but the sculptures with which it is adorned are more minute and delicate, and show a more perfect imitation of nature, than the earlier examples, though inferior to them in grandeur of conception and breadth of design. [Illustration: 70. Central Palace, Koyunjik. Scale 100 ft. to 1 in.] The architectural details also display a degree of elegance and an amount of elaborate finish not usually found in the earlier examples, as is well illustrated by the Woodcut No. 71, representing one of the pavement slabs of the palace. It is of the same design, and similarly ornamented, but the finish is better, and the execution more elaborate, than in any of the more ancient examples we are acquainted with.
