It is the dawn of history and of the dispersion of the Indo-European peoples. They are breaking their tents in central Asia along the Hindu Kush and the Pamirs, primitive Aryans with their dogs and their herds of domesticated animals. In their trek they will proceed to the farthest confines of Europe. From them the peoples of England, France, Germany, Italy, Spain, Scandinavia, Russia, Greece and other will take their origin. A part will penetrate into India and another portion into Persia. They will build empires and munitions factories, cathedrals and cabarets. Some less simple-minded, the Kurds, Lurs and Bakhtiaris will maintain in Persia their primitive character into the twentieth century. With them in their dispersion, the Aryans carry the sacred fire which they have worshiped since they became acquainted with its use. It was man's first great step in the mastery of nature.
