Johannes Fauentinus

d. 1190


Alternative Names

Johannes, Faventinus (LC); John of Faenza; Jean de Faenza; Giovanni de Faenza; Johannes Cavalerius; Magister Johannes



Born in Faenza, studied canon law in Bologna and became a professor around 1170. He immediately began his publishing career as a commentator and glossator of the Decretum, which continued undisturbed when he left Bologna, in 1174, to become a canon in Faenza. He probably has to be identified with the Bishop Johannes of Faenza (1177–90), who ruled over his diocese just about the time when Huguccio’s teachings began to gain predominance over his own. Unlike most of his colleagues, Johannes prepared the ground for his glossing activities by composing a Summa (ca. 1171). It consisted of little more than a compilation based on the two Summae of his predecessors, Rufinus and Stephan of Tournai. Modern scholars have often called him a plagiarist for that reason, despite the fact that Johannes fully acknowledged his indebtedness in the prologue. More importantly, the work was warmly welcomed by his audience, as is attested by the great number of surviving manuscripts, more twelfth century manuscripts even than for Huguccio. In addition, Johannes expressed his own doctrinal opinions in a vast amount of single glosses on all parts of Gratian’s work. They also enjoyed great success and circulated widely, in what made Johannes the most cited canonist prior to Huguccio.
