We should be in a better position to appreciate these qualities of invention and taste had time not entirely deprived us of that part of the work of the Mesopotamian architects in which they were best served by their materials. Assyria, like Egypt, practised construction "by assemblage" as well as the two methods we have already noticed. She had a light form of architecture in which wood and metal played the principal part. As might have been expected, however, all that she achieved in that direction has perished, and the only evidence upon which we can attempt a restoration is that of the sculptured monuments, and they, unhappily, are much less communicative in this respect than those of Egypt. In the paintings of the Theban tombs the kiosks and pavilions of wood and metal are figured in all the variety and vivacity derived from the brilliant colours with which they were adorned. Nothing of the kind is to be found in Mesopotamia. Our only documents are the uncoloured reliefs which, even in the matter of form, are more reticent than we could have wished. But in spite of their simplification these representations allow us to perceive clearly enough the mingled elegance and richness that characterized the structures in question. [Illustration: FIG. 67.--Interior of the Royal Tent; from Layard.] Thus in a bas-relief at Nimroud representing the interior of a fortress, a central place is occupied by a small pavilion generally supposed to represent the royal tent (Fig. 67).[243] The artist could not give a complete representation of it, with all its divisions and the people it contained. He shows only the apartment in which the high-bred horses that drew the royal chariot were groomed and fed. Before the door of the pavilion an eunuch receives a company of prisoners, their hands bound behind them, and a soldier at their elbow. Higher up on the relief the sculptor has figured the god with fish's scales whom we have already encountered (see Fig. 9). To him, perhaps, the king attributed the capture of the fortress that has just fallen into his hands. It is not, however, with an explanation of the scene that we are at present concerned; our business is with the structure of the pavilion itself, with the slender columns and the rich capitals at their summits, with the domed roof, made, no doubt, of several skins sewn together and kept in place by metal weights. The capitals and the two wild goats perched upon the shafts must have been of metal. As for the tall and slender columns themselves, they were doubtless of wood. The chevrons and vertical fillets with which they are decorated may either have been carved in the wood or inlaid in metal. [Illustration: FIG. 68.--Tabernacle; from the Balawat Gates.]
