St. Leonard of Noblac (6th century)

Leonard lived a life of austerity, sanctification, and preaching. Desiring more seclusion than a monastery could offer, he withdrew into the forest and lived on herbs, wild fruits, and spring water. There he built an oratory, which he left only for journeys to churches. He had great compassion for prisoners, many of whom he converted. (For more info go to: Catholic-Forum Patron Saint Index)
