This medieval work recounts the story of St. Livinus, a child who was baptized by Blessed Augustine and Menalchus, receiving his name in honor of a martyr. Upon his baptism, a miraculous light appeared over him, signaling his divine favor. As he matured, Livinus dedicated himself to spiritual studies and became known for his virtuous character. At a young age, he demonstrated remarkable faith by praying for and successfully exorcising two men possessed by demons. His actions were accompanied by notable signs, reinforcing his role as a champion of faith and divine mercy.
