It happened once in the merchant town (Nidaros) where King Olaf reposes,
that there broke out a fire in the town which spread around. Then
Olaf's shrine was taken out of the church, and set up opposite the fire.
Thereupon came a crazy foolish man, struck the shrine, threatened the
holy saint, and said all must be consumed by the flames, both churches
and other houses, if he did not save them by his prayers. Now the
burning of the church did cease, by the help of Almighty God; but the
insane man got sore eyes on the following night, and he lay there until
King Olaf entreated God Almighty to be merciful to him; after which he
recovered in the same church.
