“ GRATIANUS, FRANCISCUS, compiler of the Concordia discordantium canonum or Decretum Gratiani, and founder of the science of canon law, was born about the end of the 11th century at Chiusi in Tuscany or, according to another account, at Carraria near Orvieto. In early life he appears to have been received into the Camaldulian monastery of Classe near Ravenna, whence he afterwards removed to that of San Felice in Bologna, where he spent many years in the preparation of the Concordia. ”
