Monomaque now fitted out sundry expeditions under his enterprising son to extend the territories of Russia and to bring tumultuous tribes and nations into subjection and order. His son Mstislaf was sent into the country of the Tchoudes, now Livonia, on the shores of the Baltic. He overran the territory, seized the capital and established order. His son Vsevolod, who was stationed at Novgorod, made an expedition into Finland. His army experienced inconceivable sufferings in that cold, inhospitable clime. Still they overawed the inhabitants and secured tranquillity. Another son, Georges, marched to the Volga, embarked his army in a fleet of barges, and floated along the stream to eastern Bulgaria, conquered an army raised to oppose him, and returned to his principality laden with booty. Another son, Yaropolk, assailed the tumultuous tribes upon the Don. Brilliant success accompanied his enterprise. Among his captives he found one maiden of such rare beauty that he made her his wife. At the same time the kingdom of Russia was invaded by barbarous hordes from the shores of the Caspian. Monomaque himself headed an army and assailed the invaders with such impetuosity that they were driven, with much loss, back again to their wilds. The military renown Monomaque thus attained made his name a terror even to the most distant tribes, and, for a time, held in awe those turbulent spirits who had been filling the world with violence. Elated by his conquests, Monomaque fitted out an expedition to Greece. A large army descended the Dnieper, took possession of Thrace, and threatened Adrianople. The emperor, in great alarm, sent embassadors to Monomaque with the most precious presents. There was a cornelian exquisitely cut and set, a golden chain and necklace, a crown of gold, and, most precious of all, a crucifix made of wood of the true cross! The metropolitan bishop of Ephesus, who was sent with these presents, was authorized, in the name of the church and of the empire, to place the crown upon the brow of Monomaque in gorgeous coronation in the cathedral church of Kief, and to proclaim Monomaque Emperor of Russia. This crown, called the _golden bonnet of Monomaque_, is still preserved in the Museum of Antiquities at Moscow.
