Though practically absent from the great brick palaces, the column here played an important and conspicuous part. It furnished elegant and richly decorated supports for canopies of wool that softly rose and fell with the passing breeze. Fair carpets were spread upon the ground beneath, others were suspended to cross beams painted with lively colours, and swept the earth with the long and feathered fringes sewn upon their borders. [Illustration: FIG. 69.--The Seal of Sennacherib. Cylinder of green feldspar in the British Museum.] The difference was great between the massive buildings by which the Mesopotamian plains were dominated, and these light, airy structures which must have risen in great numbers in Chaldaea and Assyria, here on the banks of canals and rivers or in the glades of shady parks, there on the broad esplanades of a temple or in the courts of a royal palace. Between the mountains of clay on the one hand and these graceful tabernacles with their slender supports and gay coverings on the other, the contrast must have been both charming and piquant. Nowhere else do we find the distinction between the house and the tent so strongly marked. The latter must have held, too, a much more important place in the national life than it did either in Egypt or Greece. The monarch spent most of his time either in hunting or fighting, and his court must have followed him to the field. Moreover, when spring covers every meadow with deep herbage and brilliant flowers, an irresistible desire comes over the inhabitants of such countries as Mesopotamia to fly from cities and set up their dwellings amid the scents and verdure of the fields. Again, when the summer heats have dried up the plains and made the streets of a town unbearable, an exodus takes place to the nearest mountains, and life is only to be prized when it can be passed among the breezes from their valleys and the shadows of their forest trees.

At certain seasons some of the nomad tribes betake themselves within the walls of Bagdad and Mossoul and there set up their long black tents of goats' hair.[247] Judging from the bas-reliefs they did the same even in ancient Assyria; in some of these a few tents may be seen sprinkled over a space inclosed by a line of walls and towers.[248] Abraham and Lot slept in their tents even when they dwelt within the walls of a city.[249] Lot had both his tent and a house at Sodom.[250] Every year the inhabitants of Mossoul and the neighbouring villages turn out in large numbers into the neighbouring country, and, during April and May, re-taste for a time that pastoral life to which a roof is unknown.
