Pertaining or relating to As syria or to its inhabitants. - A yrian architecture, the most im- portant branch of the architecture of Me so pot am i a, de- veloped in As syria during the period of its supremacy. Its chief monuments were the royal palaces, which were of enormous extent, and constructed of ma ive walls of sun- dried brick on great mounds of clay, of which they have now virtually become a part, owing to the disintegrating influ- ence of time and the elements upon their friable mate- rials. They were never more than one or two stories high, owing to the limited endurance of the unbaked bricks, and consisted chiefly of corridors and long, narrow halls, either arched over with brick or closed in with ceilings of wood, and surrounding open courts. The entrances were of im- posing height and width, ornamented with colo al stone figures of winged human-headed bulls or lions, or other mythological conceptions. The interior walls were com- monly lined with a revetment of soft alabaster slabs, on which were carved in low relief the remarkable series of sculptures which have preserved the record of A yrian triumphs, character, and customs. Color in somewhat subdued tints was generally employed upon the sculptures and the wall-spaces. The temple, in As syria, was sub- ordinate to the palace, the opposite being the case in Baby- lonia.- A yrian art, one of the later branches of Meso- potamian art, parallel to the later Babylonian.
