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, and at an early age entered the Camaldulian monastery of Classe near Ravenna, whence he afterwards removed to that of San Felice in Bologna, where he prepared the Concordia, which on internal evidence seems to have been completed before 1150. He is said to have been bishop of Chiusi.
For the Decretum Gratiani and its history see CANON LAW. The best edition is that of Friedberg (Corpus juris canonici, Leipzig, 1879) . Compare Schultze, Zur Geschichte der Litteratur caber das Decret Gratians (187o) , Die Glosse zum Decret Gratians (1872) , and Ge schichte der Quellen and Litteratur des kanonischen Rechts (3 vols., Stuttgart, 1875) .
