Who they were
A monk of Wissembourg with close ties to the abbey of Fulda, Astolfo was bishop of Mainz from 814 to 826. During his episcopate he played an important part in spreading Christianity in Germany, ordaining the celebrated Benedictine monk Rabanus Maurus, author of the encyclopedic "De Universo," to the priesthood. He is remembered on 5 January in the Martyrologium Hieronymianum as bishop of Mainz, the German see that became the ecclesiastical centre of the whole country. He died at Mainz on 28 January 826.
The miracles
