During his stay at Nidaros the king ascertained that the people of the interior of the Throndhjem country were still offering sacrifices to the heathen gods for peace and a good season, and that Olver of Eggja, a mighty man in that neighborhood, presided over these sacrifice-feasts, although he had twice assured the king that the people were loyal Christians. Learning that they were preparing such a feast at Mæren, the king proceeded to that place one night with three hundred and sixty armed men, captured Olver of Eggja, and had him killed together with many others, and severely punished all the peasants who had taken a leading part in the sacrifices. In this way he brought the people back to the Christian faith, gave them teachers, and built and consecrated churches. The widow of Olver of Eggja, who was young and handsome, of good family, and rich, was given by the king in marriage to Kalf Arneson, a young favorite among the king's men. The king also gave him an office, and Kalf thus became a great chief. In the summer of 1021 King Olaf proceeded to Moere and Raumsdal. In the fall he left his ships in Raumsdal and proceeded to Gudbrandsdal. The mightiest man there was Dale-Gudbrand, who ruled over the valley districts there with the authority of a king, although he did not bear the title. When he heard that Olaf was approaching, he summoned all the men in the valley to a Thing, where they decided to resist the attempt to force Christianity upon them. A force of eight hundred men, under the leadership of Alf, the son of Gudbrand, was sent against Olaf, but a battle had scarcely begun when the peasants fled, and Alf was captured. Then the king was invited to hold a Thing with the peasants, so they could discuss the proposed change of faith. To the request of the king that the people should believe in the true God and be baptized, Dale-Gudbrand replied: "We do not understand of whom thou art speaking. Dost thou call him God whom neither thou nor any one else can see? But we have a god who can be seen every day, although he is not out to-day, because the weather is wet. I expect that fear will mix with your very blood when he comes into the Thing. Now, since thy God is so great, let him make it so that to-morrow we have a cloudy day but without rain, and then let us meet again." The next day when the Thing had assembled, the weather was such as Gudbrand had desired. Bishop Sigurd stood up in full vestments, with mitre on his head and crosier in his hand, and spoke to the peasants of the true faith, and of the many miracles that God had performed. On the third day the peasants came to the assembly carrying between them a great image of the god Thor, which they placed on the green. Dale-Gudbrand then said: "Where now, king, is thy god? I think he will now carry his head lower; and neither thou nor thy bishop are so bold to-day as on former days; for now our god, who rules over all, has come, and looks on you with an angry eye.
