Moreover, some continued secretly, others openly, to offer sacrifices to trees and springs, to inspect the entrails of victims; some practiced divination, legerdemain and incantations; some turned their attention to auguries, auspices and other sacrificial rites; whilst others, of a more reasonable character, forsook all the profane practices of heathenism and committed none of these crimes.
With the counsel and advice of the latter persons, Boniface in their presence attempted to cut down, at a place called Gaesmere, a certain oak of extraordinary size called by the pagans of olden times the Oak of Donar. Taking his courage in his hands (for a great crowd of pagans stood by watching and bitterly cursing in their hearts the enemy of the gods), he cut the first notch.
But when he had made a superficial cut, suddenly the oak's vast bulk, shaken by a mighty blast of wind from above, crashed to the ground shivering its topmost branches into fragments in its fall. As if by the express will of God (for the brethren present had done nothing to cause it) the oak burst asunder into four parts, each part having a trunk of equal length. At the sight of this extraordinary spectacle the heathens who had been cursing ceased to revile and began, on the contrary, to believe and bless the Lord.
Thereupon the holy bishop took counsel with the brethren, built an oratory from the timber of the oak and dedicated it to St. Peter the Apostle.
