a reforming monk in the circle of Pope Gregory VII and a cardinal. In 1823, he was declared a Doctor of the Church. Dante placed him in one of the highest circles of Paradiso as a great predecessor of Saint Francis of Assisi. Petrus Damiani’s voluminous writings reflect the spiritual conditions of Italy: the groundswell of intense personal piety that would overflow in the First Crusade at the end of the century was an extremely vigorous controversialist, and his Latin abounds in denunciatory epithets. He was especially devoted to the Virgin Mary, and wrote an Officium Beatae Virginis, in addition to many letters, sermons, and other writings. His most famous work is De Divina Omnipotentia, a long letter in which he discusses God’s power.
