It seems strange that such a woman should have been the first of (p. 036) Rurik's house to embrace Christianity. There is no doubt that she visited Constantinople where she astonished the emperor by the force of her character. She was baptized and received the name of Helen. It is quite possible that she came to Constantinople for that purpose, because we read that she refused to be baptized at Kief "for fear of the pagans." This confirms the Greek records in which it is stated that a bishop was established in Russia, probably at Kief, in the time of Oleg. It is not strange that Christianity should have taken root in Russia after the frequent wars with the Byzantine Empire, and considering the commerce carried on between Kief and Constantinople. Missionaries entered Russia at an early period. Two of them, Cyril and Methodius, prepared a Slavonic alphabet, in which many Greek letters were used, and the Bible was translated into that language. There is a tradition that Askold was baptized after his defeat at Constantinople, and that this is the reason why the people still worship at his tomb at Kief, as of that of the first Christian prince. The Norsemen had no taste for persecution on account of religious belief, but for themselves they clung to the heathen deities. When Igor swore to observe the treaty concluded with Emperor Leo VI, he went up to the hill of Perun and used the ancient Slavonic rites; but the emperor's deputies went to the church of St. Elias, and there laid their hands upon the Bible as a token of good faith. The drujina and warriors did not take kindly to Christianity. They, as well as the peasants, preferred to worship Perun and Voloss. The same thing happened elsewhere. Christianity made the greatest progress (p. 037) in cities, whereas the dwellers on the "heath" remained "heathen." "When one of the warriors of the prince wished to become a convert," says Nestor, "he was not prevented; they simply laughed at him." When Olga returned from Constantinople, she was anxious that her son, who was of age and had succeeded to his father, should follow her example. Sviatoslaf refused; "my men will laugh at me," was his usual answer. Nestor mentions that he sometimes lost his temper. Christianity did not make much progress during his reign. He was a warrior, like his Norse ancestors. In the brief time of eight years, 964-972, he found time to wage two wars. The first was with the Khazar empire on the Don. Sviatoslaf captured its capital, the White City, and received tribute from two tribes of the Caucasus. The second war did not turn out so well.
