If the German poet was justified in writing the words just quoted much more are we in repeating them. The interpretation of the present is to be sought in the light of the past. _Ex oriente lux_ is an old and familiar saying. In the last century there flashed from this quarter a light that astonished the world, and like the wise men of old, it came from the valley of the Tigris and Euphrates. The consequent increase in our knowledge has revolutionized much of the thought of the past, and so quietly has this been done that none but those who have been more particularly interested in the new discoveries are aware of the importance and extent of the changes made. Our views of ancient history, literature, life, religion have been greatly altered and enlarged. Europe and America have been for almost two millennia under the potent spell and inspiration of a little people who lived at the eastern end of the Mediterranean. Prophets and teachers arose among them who lifted the world off its hinges, set Greece, the home of intellect, to thinking anew, and uttered their messages through the successors of the Caesars. A wonderful people, indeed! How are they to be explained? Most certainly we must seek for their explanation in the light of their antecedents and racial affinities. It was, and is, no more possible to understand them and correctly interpret their literary remains, the Bible, apart from a knowledge of the great family of which they formed numerically only an insignificant part than it would be to understand the spirit and thought of the people of the United States if the early relations to Great Britain were unknown or ignored. The Old Testament, in its late written traditions, records that the ancestors of the Hebrews emigrated from Ur of the Chaldees, an ancient city, even in the days of Abraham, of southern Babylonia and a principal seat of the worship of the moon-god, Sin. But of the great family of the Semites--the Arabians, Babylonians, Assyrians, Canaanites, Aramaeans, Syrians, etc., little was known a century ago. Practically all scholarly interest in this group until the middle of the nineteenth century was confined to the literature and civilization of the Arabs since the Mohammedan era.
