Egypt, then, had her great convulsions like the rest of the world. She met with disasters, and underwent periods of confusion like those which overtook the nations of the West between the reigns of Trajan and Charlemagne. Wars and invasions, the action and reaction of civilization, had upon her the same influence as upon them, and, in transforming her sentiments and ideas, caused their plastic expression to pass through a series of changes in taste and style. The Theban tomb of the time of Rameses is very different from that of Memphis and the ancient empire; the new empire constructed no buildings like the greater pyramids, but its temples were larger and more magnificent than any of their predecessors. It was the same with sculpture. A cultivated eye has no need to run to inscriptions to enable it to distinguish between works of the ancient and of the middle empire; nor will it confound works created in either of those periods with those of the Sait epoch. The differences are almost as well marked as those which enable archæologists to distinguish a torso of the time of Phidias from one of the school of Praxiteles or Lysippus. These differences it will be our duty to describe hereafter, but our readers may perhaps discover them for themselves if they examine the illustrations to this chapter, which are arranged in chronological order. Variety is universal in Egypt, local variety as well as that of different periods. Language had its dialects as well as art. The pronunciation of Upper and that of Lower Egypt was quite dissimilar, except in the case of a few letters. In the same way different cities had distinct schools of sculpture and painting, which were distinguished from one another by their traditional methods of conception and execution. Neither under Ousourtesen nor under Rameses, had art the same character in the cities of the Delta, in Memphis, and in Thebes. Among the works in sculpture executed for Rameses II., those of Abydos were more elegant and refined than those of Thebes. [Illustration: FIG. 50.--The Lady Naï.

The Greeks visited Egypt too late in its history to form a true judgment. In Plato's time the Egyptians were still trying, by violent but spasmodic efforts, to reconquer the independence which had been destroyed by the successor of Cyrus. But the moment was at hand when even these intermittent struggles were to be abandoned, and they were to finally succumb to sovereigns of foreign blood. Their still brilliant civilization might deceive a passing stranger, but the decadence had commenced--a decadence slow indeed, but none the more remediable.
