The Chaldæan palace, like the Egyptian temple, sought mainly for lateral development. Its extent far surpassed its elevation, and horizontal lines predominated in its general physiognomy. There was here a latent harmony between the architecture of nature and that of man, between the great plains of Mesopotamia, with their distant horizons, and the long walls, broken only by their crenellated summits, of the temples and palaces. There must, however, have been a certain want of relief, of visibility, in edifices conceived on such lines and built in such a country.
This latter defect was obvious to the Mesopotamians themselves, who raised the dwellings of their gods and kings upon an artificial mound with a carefully paved summit.[148] Upon this summit the structure properly speaking rested, so that, in Chaldæa, the foundations of a great building instead of being, as elsewhere, sunk beneath the soil, stand so high above it that the ground line of the palace or temple to which they belong rises above the plain to a height that leaves the roofs of ordinary houses and even the summits of the tallest palms far below. This arrangement gave a clearer salience and a more imposing mass to structures which would otherwise, on account of their monotony of line and the vast excess of their horizontal over their vertical development, have had but little effect.

Such an arrangement would appear superfluous in the case of those towers in the shape of stepped pyramids, whose summits could be carried above the plain to any fanciful height by the simple process of adding story to story. But the Mesopotamian constructor went upon the same system as in the case of his palaces. It was well in any case to interpose a dense, firm, and dry mass between the wet and often shifting soil and the building, and to afford a base which by its size and solidity should protect the great accumulation of material that was to be placed upon it from injury through any settling in the foundations. Moreover, the paved esplanade had its place in the general economy. It formed a spacious court about the temple, a sacred temenos as the Greeks would have called it, a haram as a modern Oriental would say. It could be peopled with statues and decorated with mystic emblems; religious processions could be marshalled within its bounds.

The general, we may almost say the invariable, rule in Mesopotamia was that every structure of a certain importance should be thus borne on an artificial hill. An examination of the ruins themselves and of the monuments figured upon the bas-reliefs shows us that these substructures did not always have the same form. Their faces were sometimes vertical, sometimes inclined; sometimes again they presented a gentle outward curve (see [Fig. 34]); but these purely external differences did not affect the principle. In all the river basins of Mesopotamia, whether of the Euphrates, the Tigris, or the smallest affluents of the Persian Gulf, whenever you see one of these tells, or isolated mounds, standing above the general surface of the plain, you may be sure that if you drive a trench into it you will come upon those courses of crude brick that proclaim its artificial origin. Rounded by natural disintegration and scarred by the rain torrents, such a hillock is apt to deceive the thoughtless or ignorant traveller, but an instructed explorer knows at a glance that many centuries ago it bore on its summit a temple, a fortress, or some royal or lordly habitation ([Fig. 35]).
