In 1464, Fangi was made prior of the priory at Soncino, Lombardy. He is said to have performed several miracles there. One involved a deformed child who had died without baptism yet was said to have been restored to life by his prayer. Another purported miracle involved a boy who was crying bitterly because he had broken a jug of wine. Fangi gathered up the shards and put them back together again. The account continues to state that with a prayer, he refilled the jug, and handed it back to the startled child.
