“Gratian.” The little that is known concerning the author of the “Concordantia discordantium canonum,” more generally called the “Decretum Gratiani,” must be gathered from the work itself. Gratian was born in Italy, perhaps at Chiusi. He became a Camaldolese monk and taught at Balogna. It is uncertain at what time he compiled the “Decretum,” but it was commonly held to have been completed in 1151. More recent authorities, however, are inclined to suggest 1140. Gratian died before 1179, some think as early as 1160. He is regarded as the true found of the science of canon law.
