Stated in a few words, that aim is to trace the course of the great plastic evolution which culminated in the age of Pericles and came to an end in that of Marcus Aurelius. That evolution forms a complete organic whole, with a birthday, a deathday, and an unbroken chain of cause and effect uniting the two. To objectors who may say that the art of India, of China, of Japan, should have been included in the scheme, it may be answered: this is the life, not of two, or three, but of one. M. Perrot has been careful, therefore, to discriminate between those characteristics of Egyptian art which may be referred either to the national beliefs and modes of thought, or to undeveloped material conditions, such as the want or superstitious disuse of iron, and those which, being determined by the very nature of the problems which art has to solve, formed a starting point for the arts of all later civilizations. By means of well-chosen examples he shows that the art of the Egyptians went through the same process of development as those of other and later nationalities, and that the real distinguishing characteristic of the sculptures and paintings of the Nile Valley was a continual tendency to simplification and generalization, arising partly from the habit of mind and hand created by the hieroglyphic writing, partly from the stubborn nature of the chief materials employed. To this characteristic he might, perhaps, have added another, which is sufficiently remarkable in an art which had at least three thousand years of vitality, namely, its freedom from individual expression. The realism of the Egyptians was a broad realism. There is in it no sign of that research into detail which distinguishes most imitative art and is to be found even in that of their immediate successors; and yet, during all those long centuries of alternate renascence and decay, we find no vestige of an attempt to raise art above imitation. No suspicion of its expressive power seems to have dawned on the Egyptian mind, which, so far as the plastic arts were concerned, never produced anything that in the language of modern criticism could be called a creation. In this particular Egypt is more closely allied to those nations of the far east whose art does not come within the scope of M. Perrot's inquiry, than to the great civilizations which formed its own posterity. * * * * *
