(or or , second to last), and () or (last). Author Gratian () was a canon lawyer from Etruria, probably operating in the former feudal state of Matilda of Tuscany (mainly in Tuscany and Emilia region) as well as in Reims (1131), Rome, Bologna, Venice (1143) and Chiusi. He flourished in the second quarter of the twelfth century. He died on 10 August around the middle of the 12th century as bishop of Chiusi in Tuscany. Little else is known about him. He is sometimes incorrectly referred to as Franciscus Gratianus, Johannes Gratian, or Giovanni Graziano. For a long time he was believed to have been born around 1100, at Ficulle in Umbria, based on a chronicle of illustrious men of the 14th century attributed to an exponent of the powerful Colonna family, who had possessions in Ficulle. He was said to have become a monk at Camaldoli and then taught at the monastery of St. Felix in Bologna and devoted his life to studying theology and canon law, but contemporary scholars do not attach credibility to these traditions. Since the 11th century, some cities of central-northern Italy such as Arezzo, Pisa, Bologna had been the centre of the study of Roman law, after the was rediscovered in western Europe. In the second half of the 11th century and at the beginning of the 12th century Roman law was generally studied and applied only in the cities (seat of the diocese) in which there was an imperial Prefecture, where imperial and ecclesiastical jurists (and courts) coexisted (such as Pisa and Bologna), with mutual interference. However, from the first editorial stages of the it is clear that Gratian had little knowledge of Roman law and that he had a great sense of depth in the disputes dealt with in the ecclesiastical seats, especially in the appeal judgments dealt with in the Roman curia. Therefore, some scholars today exclude that he was trained in Justinian Roman law and that (at the beginning of his career) he worked mainly in certain cities (such as Arezzo, Pisa or Bologna) where Roman law was known and applied for years, it being plausible that he came from an episcopal city in which all jurisdiction, both civil and ecclesiastical, was dealt with by the only court present: the ecclesiastical one. Perhaps also for this reason he feels the need to create a legal work to be applied
