To settle the question he sent ten of his chief boyars, or nobles, to the south, that they might examine and report on the religions of the different countries. They were not long in coming to a decision. Mohammedanism and Catholicism, they said, they had found only in poor and barbarous provinces. Judaism had no land to call its own. But the Greek faith dwelt in a magnificent metropolis, and its ceremonies were full of pomp and solemnity. "If the Greek religion were not the best," they said, in conclusion, "Olga, your ancestress, and the wisest of mortals, would never have thought of embracing it." Pomp and solemnity won the day, and Vladimir determined to follow Olga's example. As to what religion meant in itself he seems to have thought little and cared less. His method of becoming a Christian was so original that it is well worth the telling. Since the days of Olga Kief had possessed Christian churches and priests, and Vladimir might easily have been baptized without leaving home. But this was far too simple a process for a prince of his dignity. He must be baptized by a bishop of the parent Church, and the missionaries who were to convert his people must come from the central home of the faith. Should he ask the emperor for the rite of baptism? Not he; it would be too much like rendering homage to a prince no greater than himself. The haughty barbarian found himself in a quandary; but soon he discovered a promising way out of it. He would make war on Greece, conquer priests and churches, and by force of arms obtain instruction and baptism in the new faith. Surely never before or since was a war waged with the object of winning a new religion. Gathering a large army, Vladimir marched to the Crimea, where stood the rich and powerful Greek city of Kherson. The ruins of this city may still be seen near the modern Sevastopol. To it he laid siege, warning the inhabitants that it would be wise in them to yield, for he was prepared to remain three years before their walls. The Khersonites proved obstinate, and for six months he besieged them closely. But no progress was made, and it began to look as if Vladimir would never become a Christian in his chosen mode. A traitor within the walls, however, solved the difficulty. He shot from the ramparts an arrow to which a letter was attached, in which the Russians were told that the city obtained all its fresh water from a spring near their camp, to which ran underground pipes. Vladimir cut the pipes, and the city, in peril of the horrors of thirst, was forced to yield. Baptism was now to be had from the parent source, but Vladimir was still not content. He demanded to be united by ties of blood to the emperors of the southern realm, asking for the hand of Anna, the emperor's sister, and threatening to take Constantinople if his proposal were rejected.
