But if we calmly consider the real facts, avoiding the optical illusion that makes things in our immediate {2} vicinity look larger, we shall form a quite different opinion. It is beyond all dispute that Rome found the point of support of its military power in the Occident. The legions from the Danube and the Rhine were always braver, stronger and better disciplined than those from the Euphrates and the Nile. But it is in the Orient, especially in these countries of "old civilization," that we must look for industry and riches, for technical ability and artistic productions, as well as for intelligence and science, even before Constantine made it the center of political power. While Greece merely vegetated in a state of poverty, humiliation and exhaustion; while Italy suffered depopulation and became unable to provide for her own support; while the other countries of Europe were hardly out of barbarism; Asia Minor, Egypt and Syria gathered the rich harvests Roman peace made possible. Their industrial centers cultivated and renewed all the traditions that had caused their former celebrity. A more intense intellectual life corresponded with the economic activity of these great manufacturing and exporting countries. They excelled in every profession except that of arms, and even the prejudiced Romans admitted their superiority. The menace of an Oriental empire haunted the imaginations of the first masters of the world. Such an empire seems to have been the main thought of the dictator Caesar, and the triumvir Antony almost realized it. Even Nero thought of making Alexandria his capital. Although Rome, supported by her army and the right of might, retained the political authority for a long time, she bowed to the fatal moral ascendency of more advanced peoples. Viewed from this standpoint the history of the empire {3} during the first three centuries may be summarized as a "peaceful infiltration" of the Orient into the Occident.[2] This truth has become evident since the various aspects of Roman civilization are being studied in greater detail; and before broaching the special subject of these studies we wish to review a few phases of the slow metamorphosis of which the propagation of the Oriental religions was one phenomenon.
