He was a French saint who became a monk when he was five years old. He spent nearly all of his time, night and day, in prayer. He was a Benedictine. When made a bishop, he lived in his palace just like a monk. He fed people with his own hands. He constantly visited the hospitals where the sick, and even the lepers were kept. He was a great opponent of the greed and laxity of the clergy of his day.
