Leo the Great
400 CE–461 CE · Mincio River (near Mantua)
Leo the Great (c. 400–461) served as Bishop of Rome from 440 until his death, making him one of the most influential popes of antiquity. His Tome of Leo, a letter on the two natures of Christ, was formally endorsed at the Council of Chalcedon (451) and shaped orthodox Christology. He is traditionally credited with persuading Attila the Hun to withdraw from Italy in 452 through a personal embassy near the Mincio River. A skilled administrator and preacher, he asserted Roman primacy with exceptional force and was posthumously declared a Doctor of the Church.
