Igor was one day engaged in the chase, when at the door of a cottage, in a small village near Kief, he saw a young peasant girl, of marvelous grace and beauty. She was a Norman girl of humble parentage. Young Igor, inflamed by her beauty, immediately rode to the door and addressed her. Her voice was melody, her smile ravishing, and in her replies to his questionings, she developed pride of character, quickness of intelligence and invincible modesty, which charmed him and instantly won his most passionate admiration. The young prince rode home sorely wounded. Cupid had shot one of his most fiery arrows into the very center of his heart. Though many high-born ladies had been urged upon Igor, he renounced them all, and allowing beauty to triumph over birth, honorably demanded and received the hand of the lowly-born yet princely-minded and lovely Olga. They were married at Kief in the year 903. The revolution at Kief had not interrupted the friendly relations existing between Kief and Constantinople. The Christians of the imperial city made great efforts, by sending missionaries to Kief, to multiply the number of Christians there. Oleg, though a pagan, granted free toleration to Christianity, and reciprocated the presents and friendly messages he received from the emperor. But at length Oleg, having consolidated his realms, and ambitions of still greater renown, wealth and power, resolved boldly to declare war against the empire itself, and to march upon Constantinople. The warriors from a hundred tribes, each under their feudal lord, were ranged around his banners. For miles along the banks of the Dnieper at Kief, the river was covered with barges, two thousand in number. An immense body of cavalry accompanied the expedition, following along the shore. The navigation of the river, which poured its flood through a channel nearly a thousand miles in length from Kief to the Euxine, was difficult and perilous. It required the blind, unthinking courage of semi-barbarians to undertake such an enterprise. There were many cataracts, down which the flotilla would be swept over foaming billows and amidst jagged rocks. In many places the stream was quite impassable by boats, and it was necessary to take all the barges, with their contents, on shore, and drag them for miles through the forest, again to launch them upon smoother water; and all this time they were exposed to attacks from numerous and ferocious foes. Having arrived at the mouth of the Dnieper, they had still six or eight hundred miles of navigation over the waves of that storm-swept sea. And then, at the close, they had to encounter, in deadly fight, all the power of the Roman empire. But unintimidated by these perils, Oleg, leaving Igor with his bride at Kief, launched his boats upon the current, and commenced his desperate enterprise. CHAPTER II.
