Leonard was one of the most renowned saints during the Western Middle Ages. His biography, written in the 11th century, reports that he was a noble man converted to Christianity by Saint Remi, in 496, therefore at the same time as Clovis, one of the oldest kings of France.1 Leonardo obtained from his sovereign the right to visit and possibly release the prisoners he deemed worthy of release, at any time. And it is because he freed a large number of prisoners that he became the patron saint of prisoners.
