This view of the question is not based upon any error. In regard to the possible destruction of Philae by the force of the water, Mr Somers Clarke, F.S.A., whose name is known all over the world in connection with his work at St Paul's Cathedral and elsewhere, states definitely[1] that he is convinced that the temples will not be overthrown by the flood, and his opinion is shared by all those who have studied the matter carefully. Of course it is possible that, in spite of all the works of consolidation which have been effected, some cracks may appear; but during the months when the temple is out of water each year, these may be repaired. I cannot see that there is the least danger of an extensive collapse of the buildings; but should this occur, the entire temple will have to be removed and set up elsewhere. Each summer and autumn when the water goes down and the buildings once more stand as they did in the days of the Ptolemies and Romans, we shall have ample time and opportunity to discuss the situation and to take all proper steps for the safeguarding of the temples against further damage; and even were we to be confronted by a mass of fallen ruins, scattered pell-mell over the island by the power of the water, I am convinced that every block could be replaced before the flood rose again. The temple of Maharraka was entirely rebuilt in three or four weeks. [Footnote 1: Proc. Soc. Antiq., April 20, 1898.] Now, as to the effect of the water upon the reliefs and inscriptions with which the walls of the temples at Philae are covered. In June 1905 I reported[1] that a slight disintegration of the surface of the stone was noticeable, and that the sharp lines of the hieroglyphs had become somewhat blurred. This is due to the action of the salts in the sandstone; but these salts have now disappeared, and the disintegration will not continue. The Report on the Temples of Philae, issued by the Ministry of Public Works in 1908, makes this quite clear; and I may add that the proof of the statement is to be found at the many points on the Nile where there are the remains of quay walls dating from Pharaonic times. Many of these quays are constructed of inscribed blocks of a stone precisely similar in quality to that used at Philae; and although they have been submerged for many hundreds of years, the lines of the hieroglyphs are almost as sharp now as they ever were. The action of the water appears to have little effect upon sandstone, and it may thus be safely predicted that the reliefs and inscriptions at Philae will not suffer.
