(Petrus Damiani, also Pietro Damiani or Pier Damiani; c. 1007 - February 21/22, 1072) was 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.Peter was born at Ravenna, orphaned early, and after a youth spent in hardship and privation, showed such signs of remarkable intellectual gifts that his brother, Damian, who was archpriest at Ravenna, took him away to be educated. Adding his brother's name to his own, Peter made such rapid progress in his studies of theology and Canon law, first at Ravenna, then at Faenza, finally at Parma, that when about twenty-five years old he was already a famous teacher at Parma and Ravenna.
