That stream is modern European history. It has been recorded in thousands of volumes, many of which, however, are totally unreliable fables of those mighty events. Those only have had the key to its right interpretation who have followed the Christian light given from above, as a star, to guide the wonderful giant in his course. The chief among them were: of old, Augustine, the author of the "City of God;" Orosius, the first to condense the annals of the world into the formula, "_divina providentia regitur mundus et homo;_" Otho of Freysinguen, in his work "_De mutatione rerum;_" and the author of "_Gesta Dei per Francos;_" in modern times, Bossuet and his followers. The destruction of idolatry was of such vital importance in the regeneration of the world that it sufficed as a dogma to imbue a great branch of the Semitic family with a strong life for several centuries. Moslemism has no other truth to support it than the assertion of God's unity; but, by waging war against the Trinity and, consequently, against the very foundation of Christian belief, it became, for a long time, the greatest obstacle to the dissemination of truth. It prevented the early triumph of the Caucasian race, and galvanized, for a time, the nations of the East and South into a false life. The ravages of the Tartar hordes under Genghis Khan and his successors were in no sense life, but only a fitful madness. The European stream was thus impeded in its flood by the new activity of Arabia and Turkomania. It was a struggle in which victory, for a long time, hung in the balance: it required many crusades of the whole of Western Europe; the long heroism of the Spanish and Portuguese nations; the incessant attack and defence of the Templars and the Knights of Malta over the whole surface of the Mediterranean Sea, to secure the preponderance of the West. It was finally decided at Lepanto. Since that great day, Mohammedanism has gradually declined, and there now seems no insurmountable obstacle to the free flowing of the European stream. This stream, however, is not homogeneous: far from it. Had the Christian element always remained alone in it, or at least supreme, long ere this the victory would have been secure forever, and the Catholic missions alone would have fulfilled the old prophecies and given to the sons of Japhet possession of the tents of Sem--a glorious work so well begun in the East, in India and Japan; in the West, in the whole of America!
