Temple of Nebo, rebuilt by Nebuchadnezzar at Borsippa. Only four stages of the latter survive, but a record discovered in the ruins shows that the original number was seven, dedicated to the seven planets and decorated with the colours sacred to each. The ground story of this temple was 272 feet square and 45 feet high, while the total height of the structure was about 160 feet. It is noteworthy that the tomb-pyramid of Medum also consisted of seven stories.

In a ziggurat at Tello, opened up by the French savant, de Sarzac, was discovered a magnificent collection of statues of diorite—a mixture of granite, felspar and hornblende—dark grey in colour—which is now in the Louvre. One of these, which has lost its head, represents a certain Gudea, priest-king and architect of Lagash. He is seated and carries on his lap a tablet, on which a fortified enclosure is engraved, while in the corner appear a dividing scale and a stylos.

Sargon’s Castle.—The oldest palace remains have been discovered at Nimroud, the ancient Calah. They belong to the palace of Assur-nazar-pal (885-860 B.C.). Ten miles to the northeast, at Khorsabad, the French explorer P. E. Botta, discovered in 1843 the remains of a tower and palace, which subsequent excavations have proved to be the ruins of Dur-Sharrukim, “Sargon’s Castle,” built by Sargon as a royal residence (705-702 B.C.). The remains of the palace, being the most extensive of those hitherto explored, can be studied as a type of Assyrian palace architecture.

The platform on which the palace stood, constructed of sun-dried bricks and faced with cut stone, reaches the immense size of nearly a million square feet, raised forty-eight feet above the surrounding level country. The total platform, therefore, measured about 23 acres, as compared with the 3½ acres occupied by the Capitol at Washington, or the 8 acres occupied by the Houses of Parliament in London. Making allowance for the fact that the Assyrian Palace did not extend over the whole of the platform space, its actual dimensions must have been approximately twice as large as the Houses of Parliament and four and a half times those of the Capitol.

Leading up from the level on the northeast side appears to have been a double ramp, for the use of chariots and for general service, while the state entrance was at the southeast by a double flight of steps. These mounted to a terrace that extended the whole length of the palace front, some 900 feet. In the centre of this façade was the principal gate, which was small in actual size, but flanked by two tower-like projections of masonry. These, for the moment, may recall the pylons that flanked the entrance to an Egyptian temple. But the latter stately structures, built with a batter and crowned with a cavetto cornice, were designed for monumental dignity. On the other hand, the towers of Sargon’s Castle were pierced near the top with loop-holes and surmounted by battlements. They were designed to serve the purpose of warlike defence and suggest appropriately that the entrance is not only to a palace but also to the castle or stronghold of a feudal chieftain. The same suggestion is prolonged in the battlemented walls, free of windows and only occasionally pierced with loopholes, which seem to have surrounded the entire structure.

Gateway.—The towers were embellished with a notably structural decoration, a system of rectangular panelling, filled with semi-circular shafts. The ornamental details were derived from the Chaldæan use of glazed tiles, decorated with rosettes, palmettes, lotus-flowers and the guilloche or repeat of intertwined bands, arching round a central button. Similarly decorated is the archivolt which surrounds the arch of the entrance, the latter being a barrel- or semi-circular-vaulted passageway, carried right through the thickness of the walls.

Colossal Bulls.—In Egypt the entrance to the temples was made solemn and magnificent by colossal statues of the monarch. Here, the beholder must have been filled with awe by the colossal monsters that stood as guardians of the portal, projecting from the side-posts of the gateway and ranged in pairs at the foot of each tower. These monsters, which are now in the British Museum, fitly embody the warlike ideals of the Assyrian nation. They loom up in height to twelve feet. Their bodies are those of bulls, mighty in bulk and thews; yet they are quick to attack, having eagle’s wings, while dominating them is the head of a man, large-eyed, thick-lipped, square of jaw and hairy, implacably sensual and cruel.

The modeling of these monsters is for the most part as broad as a Barye bronze; though minute detail is attained in the sculpturing of the beards, hair and head-dresses. But, while their treatment is in the main naturalistic, their motive is not representation of nature, but the representation of an idea through natural suggestion. Accordingly, each embodiment has five legs; the two forelegs, planted side by side, being supplemented by another in the act of walking; so that whether the monster be viewed from the front or the side, the full significance of the legs is emphasised—the forelegs representing firmly established power; the side view showing the legs in free and powerful movement.

No Columns.—The arched entrance leads into a large open court that corresponds to the great court of an Egyptian temple, although here the sides are not embellished with colonnades. For, nowhere in Assyrian architecture has the column been found as a structural member. The single example which has been excavated, measured only three feet four inches in height and, it is conjectured, was used for a pavilion, possibly to support an awning. The absence of columnar construction in the early buildings of the Lower Kingdom is easily accounted for by the scarcity of stone; and the northern builders in dispensing with columns were only following their usual habit of imitation.

No Windows.—Meanwhile, another reason for the absence of columns may be found in the fierce heat of Mesopotamia, against which colonnades would prove no protection. The same cause explains the absence of windows in Assyrian palaces, for none have been found or shown in any of the bas-reliefs. It has been considered possible that such light as was needed was admitted through terra-cotta pipes or cylinders, for many of the latter have been come upon in the ruins and this method is still employed in the East for the lighting of domes.

?Barrel Vaults?—Another feature of the interior construction was the immense thickness of the walls, which varied from nine to twenty-five feet in solid brickwork. The object may have been to secure additional coolness, but this reason will scarcely afford a complete explanation of the extreme measurement. It is significant that the latter occurs in the halls of state which are also distinguished by their great length of 150 feet as compared with the width, 30 feet. When the narrow width of the halls is considered in relation to the immense thickness of the walls, it seems reasonable to conclude that the latter were intended to support the downward strain of barrel-vaulted ceilings. Additional probability is given to this conclusion by La Place’s discovery of great blocks, curved like the soffits of a vault, which had apparently fallen from a height. Moreover, in a bas-relief found by Layard in Koyunjik some of the buildings are shown to be roofed on the outside by domes. Accordingly, it is now the generally accepted belief that the usual style of ceiling employed by the Assyrians, was the barrel-vault.

The origin of the latter may be found in the culverts by which the mounds were drained; but how, considering the scarcity of timber, it was possible to construct vaults of thirty feet span, is purely a matter of conjecture. It has been suggested that, while timber was costly, slave-labour was cheap, and it is possible that temporary structures of brick were erected as an underpinning to support the vault while in process of construction. On the other hand, we shall note later on that the architects of Gothic cathedrals, in countries where timber was scarce, adopted the method of rib-vaulting. Can it be possible that this invention was anticipated by the Assyrians?

Decorations.—The walls of these halls of state were decorated up to a height of nine feet with sculptured slabs of delicate white alabaster or brilliantly yellow limestone, on which traces of paint have been discovered. As in the case of the Egyptian temples, scenes of everyday life, as well as of war or hunting, are represented, with a vividness that shows how closely nature had been studied by the sculptors, who, however, were more intent upon representing the spirit of the scene and preserving the feeling of decoration than in imitating nature.

Thus, when they represented an archer, stretching his bow, neither the string nor the arrow was allowed to cut the lines of the figure. Both were shown as if the hand which held them were on the opposite side of the body. It is needless to say that this could not have been due to ignorance or negligence on the part of the sculptor, who otherwise proved his knowledge and observation of nature; but was a deliberate kind of conventionalisation, adopted, like the five legs of the colossal bulls, for a well-considered purpose—perhaps, not to interfere with the action of the figure.

Above the dado of sculpture the walls were embellished with glazed tiles, decorated with winged figures of the King, and occasionally with animals, especially lions, framed with borders of rosettes. The usual colours were yellow, blue, green, and black. Coloured tiles also, as well as slabs of alabaster, formed the paving of the floors, which, in the case of smaller rooms, were formed merely of stamped clay, covered, no doubt, while in use, with mats or rugs.

Wall paintings of figures and arabesques seem to have been an exceptional form of decoration, found at Khorsabad only in the larger rooms of the harem.

Yet for all this brilliance of decoration, the effect of the interiors must have been one of subdued richness. The imagination, indeed, pictures the vast palace with its labyrinth of seven hundred rooms, surrounding three sides of the entrance court, where the glare of sunshine would be pitiless, as a sort of subterranean arrangement of tunnel-like passages and chambers.

Their distribution can be studied in the ground plan restoration. There were three groups, each disposed around its own central court. On the left of the main court lay the harem, with its separate provision for four wives, while on the opposite side was accommodation for the service, including kitchen, bakery, wine cellars, and stables. Fronting the main entrance were the King’s suite of rooms and the quarters of his official staff, beyond which were the halls of state. In the open space, adjoining the royal rooms, rose the ziggurat, or terraced temple, the three lower stories of which still exist, connected by a winding ramp.

The conception that one gathers of this huge pile is, externally, of a stronghold, somewhat forbidding; internally, of a crypt-like maze, offering perhaps comfort, but little beauty—the lair of the absolute monarch of a race to whom the market-place and fields of battle and hunting represented the chief ideals of existence.
