Book of Saints – Leo IV


(Saint) Pope (July 17) (9th century) The son of a Roman nobleman, educated in the monastery of Saint Martin, and ordained priest by Pope Sergius III, at whose death (A.D. 847) he succeeded to the Pontificate. He repaired the Confession or Shrine of Saint Peter, and with the help of the Emperor Lothaire, enclosed the whole Vatican Hill with a wall (the Leonine City), to prevent the incursions of the marauding bands then overrunning Italy. Chiefly by his prayers and by his exhortations to the soldiers, the Saracens from Calabria were utterly routed at Ostia. He did much to reform Ecclesiastical discipline, and held a Council in Rome with that object. He received King Ethelwulph of England, who came a pilgrim to Rome with his son Alfred, and at his father’s recpiest Leo anointed Alfred King. Saint Leo died July 17, A.D. 855, and was succeeded bv Benedict III.
