If the nature of the soil forced the Mesopotamian architect to build with bricks, the neighbourhood of rivers and canals for irrigation and the want of outlet for the water obliged him at the same time to have recourse to an expedient peculiar to Chaldæo-Assyrian architecture. He had to raise the actual dwelling on an artificial terrace removed from the level of a soil impregnated with unwholesome damp. This platform or basement of unbaked brick on which the building was placed is met with everywhere, not only at Nineveh and Babylon, but from the beginning in the substructures of Mugheir, Tello, Warka, and Abu Shahrein. In the palace of the patesi Gudea, the mass forms a sort of immense pedestal 39 ft. high, and nearly 655 ft. at the base; at the present day the sides form in relation to the plain a slope of 164 ft. Formerly the platform was mounted by a gentle slope intended for horses and chariots, and by one or more flights of steps which broke the outline of the terrace. The stone staircases by which the terrace of the palaces of Persepolis is ascended, are still in place; in Chaldæa and Assyria, where they were built of brick, they have almost everywhere disappeared. However, Taylor discovered two on the side of the platform of the palace of Abu Shahrein; one has only twelve steps 2 ft. broad; but the other was a monumental staircase of stone, 16 ft. broad, with a slope of more than 65 ft.
The edifice which surmounts the platform at Tello is of bricks cemented together with bitumen; its exterior walls are 5 ft. 10 in. thick, and form a parallelogram 173 ft. long and 101 ft. broad. Like the palaces of Warka and Mugheir, its orientation is according to the Assyrian custom—that is to say, the angles are turned towards the cardinal points, not the sides as in the Egyptian monuments. The two longer sides bulge slightly towards the middle, thus describing two opposite elliptical curves—a peculiarity which gives to the plan of the edifice something of the appearance of

a barrel, or of two trapeziums joined at the base. The outer surface of the walls is not everywhere uniform and flat; the adjacent sides of the northern angle are ornamented by projections alternately curved and rectilineal—a system of decoration which has also been observed at Warka, among the ruins of the temple called Wuswas, and is found later in the Assyrian monuments. The great north-eastern façade exhibits in the middle, besides the outward swell of which we have spoken, a projection 3 ft. 3 in. thick and 18 ft. long. The wings of this projection are formed of square pilasters and half-columns 1 ft. 7 in. in diameter, which recall the clustered pillars of our cathedrals, and form one of the most interesting peculiarities of the primitive architecture of Chaldæa.
