This early Frankish work narrates the story of Florus, a nobleman and son of King Flori, who arrives in Constantinople after Constantine's death. He entrusts his young son to Emperor Constantius, who raises him as a soldier. However, Florus chooses to serve God over engaging in military life. He is depicted as a virtuous individual dedicated to his faith, performing miracles and leading a life of humility despite his noble lineage. His commitment to Christianity is emphasized through his rejection of worldly pleasures and his dedication to helping others, showcasing a remarkable blend of piety and selflessness.
