The difficulties attaching to every theory of roofing and lighting which places the whole of an Assyrian palace under covert, has led some to suggest that the system actually adopted in the larger apartments was that _hypoethral_ one which is generally believed to have prevailed in the Greek temples, and which was undoubtedly followed in the ordinary Roman house. Mr. Layard was the first to post forward the view that the larger halls, at any rate, were uncovered, a projecting ledge, sufficiently wide to afford shelter and shade, being carried round the four sides of the apartment while the centre remained open to the sky. The objections taken to this view are--first, that far too much heat and light would thereby have been admitted into the palace; secondly, that in the rainy season far too much rain would have come in for comfort; and, thirdly, that the pavement of the halls, being mere sun-dried brick, would, under such circumstances, have been turned into mud. If these objections are not removed, they would be, at any rate, greatly lessened by supposing the roofing to have extended to two-thirds or three-fourths of the apartment, and the opening to have been comparatively narrow. We may also suppose that on very bright and on very rainy days carpets or other awnings were stretched across the opening, which furnished a tolerable defence against the weather. On the whole, our choice seems to lie--so far as the great halls are concerned--between this theory of the mode in which they were roofed and lighted, and a supposition from which archaeologists have hitherto shrunk, namely, that they were actually spanned from side to side by beams. If we remember that the Assyrians did not content themselves with the woods produced in their own country, but habitually cut timber in the forests of distant regions, as, for instance, of Amanus, Hermon, and Lebanon, which they conveyed to Nineveh, we shall perhaps not think it impassible that they may have been able to accomplish the feat of roofing in this simple fashion even chambers of thirteen or fourteen yards in width. Mr. Layard observes that rooms of almost equal width with the Assyrian halls are to this day covered in with beams laid horizontally from side to side in many parts of Mesopotamia, although the only timber used is that furnished by the indigenous palms and poplars. May not more have been accomplished in this way by the Assyrain architects, who had at their disposal the lofty firs and cedars of the above mentioned regions? If the halls were roofed in this way, they may have been lighted by _louvres_; or the upper portion of the walls, which is now destroyed, may have been pierced by windows, which are of frequent occurrence, and seem generally to be some-what high placed, in the representations of buildings upon the sculptures.
