Berlin to Bagdad! How these words, during the past few years, have stirred the chancelleries of Europe and how they have echoed and reëchoed throughout the civilized world! How they evoke Macchiavellian schemes of rival powers for territorial expansion and recall prolonged diplomatic struggles and countless sanguinary battles for military and commercial supremacy! How they tell of a welter of intrigue, of ambitions foiled, of treaties violated, of nations plunged into the miseries and horrors of the most frightful and most destructive of wars! No portion of the world’s surface in the entire history of humanity has witnessed so many and so great revolutions as has that narrow strip which connects what was once the palm-embowered capital of Harun-al-Rashid, near the reputed birthplace of our race, with the once proud metropolis of the Hohenzollerns in far distant Niflheim. Across this restricted belt have swept Babylonians and Assyrians, Persians and Greeks, Saracens and Mongols in their careers of rapine and conquest. And across it surged the countless hordes of Huns and Goths, Turks and Tartars, during that protracted migration of nations from the arid steppes of Asia to the fertile plains of Europe. And across it, too, at the head of their victorious armies, forced their way all projectors of world domination from Ashurbanipal and Alexander to Timur and Napoleon. As a boy no part of the world possessed a greater fascination for me than Babylonia and Assyria. This was, probably, because the first book I ever read contained wonderful stories of the Garden of Eden; of Babylon and its marvelous hanging gardens; of Nineveh and its magnificent temples and palaces; of the Tigris and the Euphrates whose waters were made to irrigate the vast and fecund plain of Mesopotamia, the cradle of civilization. So profound, indeed, was the impression made on me by the reading of this volume that one of the great desires of my life was one day to be able to visit the land whose history had so fascinated my youthful mind and whose people had played so conspicuous a rôle in the drama of human progress.
