Those vast realms of northern Europe, now called Russia, have been inhabited for a period beyond the records of history, by wandering tribes of savages. These barbaric hordes have left no monuments of their existence. The annals of Greece and of Rome simply inform us that they were there. Generations came and departed, passing through life's tragic drama, and no one has told their story. About five hundred years before the birth of our Saviour, the Greeks, sailing up the Bosphorus and braving the storms of the Black Sea, began to plant their colonies along its shores. Instructed by these colonists, Herodotus, who wrote about four hundred and forty years before Christ, gives some information respecting the then condition of interior Russia. The first great irruption into the wastes of Russia, of which history gives us any record, was about one hundred years before our Saviour. An immense multitude of conglomerated tribes, taking the general name of Scythians, with their wives and their children, their flocks and their herds, and their warriors, fiercer than wolves, crossed the Volga, and took possession of the whole country between the Don and the Danube. These barbarians did not molest the Greek colonies, but, on the contrary, were glad to learn of them many of the rudiments of civilization. Some of these tribes retained their ancestral habits of wandering herdsmen, and, with their flocks, traversed the vast and treeless plains, where they found ample pasture. Others selecting sunny and fertile valleys, scattered their seed and cultivated the soil. Thus the Scythians were divided into two quite distinct classes, the herdsmen and the laborers. The tribes who then peopled the vast wilds of northern Europe and Asia, though almost innumerable, and of different languages and customs, were all called, by the Greeks, Scythians, as we have given the general name of Indians to all the tribes who formerly ranged the forests of North America. The Scythians were as ferocious a race as earth has ever known. They drank the blood of their enemies; tanned their skins for garments; used their skulls for drinking cups; and worshiped a sword as the image or emblem of their favorite deity, the God of War. Philip of Macedon was the first who put any check upon their proud spirit. He conquered them in a decisive battle, and thus taught them that they were not invincible. Alexander the Great assailed them and spread the terror of his arms throughout all the region between the Danube and the Dnieper. Subsequently the Roman legions advanced to the Euxine, and planted their eagles upon the heights of the Caucasus.
