402 A History of Art in Ancient Egypt. inside. Of this the temple of Amenophis III. at Eilithyla, a plan and section of which we take from Lepsius (Figs. 232 and 233),^ is an instance. It is prefaced by a chamber, very ruinous, and wider than it is deep. It is now difficult to say whether this was an uncovered court or a hypostyle hall.^ Immediately abut- ting upon it comes the naos, a rectangular chamber measuring internally 28 feet by 22 feet 6 inches. The roof might very pos- sibly have been supported by the four columns, as their bases were 4 feet in diameter. A niche contrived in the further wall of the naos acted the part of a secos. Here too we find a very simple form of temple, but the naos being large enough to admit, and even to demand, the use of internal columns, it never entered the architect's head to surround it with a portico externally. Thus arranged, the chapel, as we have called these buildings, was nothing more than an epitome of the temple, and there is no need for insistance upon the variations which it presents upon a single theme, upon a first principle which sometimes was developed into a colossal structure like that at Karnak, sometimes reduced until it resulted in buildings where a few paces carry the visitor from one extremity to the other. We may say the same of those subterranean temples which are called speos or hemi-speos, grotto, or half -grot to, according to whether they are entirely rock cut, or prefaced by architectural constructions. They are chiefly found in Lower Nubia, a fact which has sometimes been explained by the natural configuration of the soil. Tn that portion of the Nile Valley the river is embraced so closely by the rocks between which it flows that it would, we are told, have been difficult to find a site for a con- structed temple. In this, however, there is some exaggeration. If we examine a map of Nubia we shall find many places where either one or the other of the two chains of hills fall back from the river far enouQrh to allow a considerable intervening fringe of level ground. This is cropped and tilled by little groups of natives, who live, as a rule, at the mouth of those wadis, or dry torrent beds, which intersect the mountains.
