The cella is an oblong square; its walls are covered with hieroglyphics and sculptures: on one side of it is a dark apartment, opening into the pronaos, and on the other side is a staircase leading up to the top of the temple: below the staircase are several small rooms. The adytum, which is entered through a narrow chamber, three paces in breadth, is ten feet in length by nine in breadth; in its posterior wall are two fine monolith temples of granite, the largest of which is eight feet in height by three in breadth; the winged globe is sculptured over each of them. They appear to have been receptacles for some small sacred animals, perhaps beetles. The places are yet visible where turned the hinges of the door, which shut up whatever was contained within. These monolith temples are similar to those at Philæ; but differ in their construction from that at Gaou (_Antæopolis_), which is much larger:[59] nor are there any hieroglyphics in the interior, whereas that at Gaou is covered on the inside with inscriptions and sculptures, some of the latter representing scarabæi. On each side of the adytum at Debot is a small room, communicating with the narrow chamber behind the cella; the walls of both are without sculptures, but contain some secret recesses, similar to those at Kalabshe, and which were destined, probably, for the same purposes. One of these rooms had an upper story, like the one at Kalabshe, but it is now ruined; the other apartments of the temple are in good preservation. The sculptures on the inside walls are much defaced; but some faint remains of their colouring are yet visible. There are no sculptures whatever on the exterior walls. A wall, now in ruins, had encompassed the whole of this temple, including the three gateways in front of it. I observed in the broken-up floor of the pronaos deep stone foundations, upon which the temple is built. I should not be surprised if subterraneous rooms were discovered here, as well as in other Egyptian temples: they would be quite in the spirit of the Egyptian hierarchy. The temple of Debot appeared to me to have been built at an epoch when the arts had begun to decline in Egypt. Its columns and sculptures are imitations of those at Philæ, but far inferior in beauty, to their models: the small temple at Merowau seemed to be about the same age, though of more careful execution. We thus find in Nubia specimens of all the different æras of Egyptian architecture, the history of which indeed can only be traced in Nubia; for all the remaining temples in Egypt (that of Gorne, perhaps, excepted) appear to have been erected in an age when the science of architecture had nearly attained to perfection. If I were to class the Nubian temples according to the probable order of their erection, it would be as follows: 1, Ebsambal. 2, Gyrshe. 3, Derr. 4, Samne. 5, Ballyane. 6, Hassaya. 7, Seboua. 8, Aamara, and Kalabshe. 9, Dakke, and Meharraka. 10, Kardassy. 11, Merowau. 12, Debot. 13, Korty. 14, Tafa.
