Bishop and canonist; d. Verona, Oct. 22, 1185. Little is known of Omnibonus's early life other than that he was a student of Gratian. He taught Canon Law at Bologna during the pontificate of Pope Eugene III and also later at Verona. In 1157 he became bishop of Verona, a post he held until his death. As a canonist, he was one of the early members of the group later known as the decretists (i.e., those whose main concern was to comment on the Decretum of gratian). He is very likely the author of the Abbreviatio Decreti, a reordered version of Gratian's Decretum. Omnibonus's Abbreviatio is divided into two parts, 26 distinctions and 37 causae. It was glossated upon by later canonists, but it does not appear to have played a very important role in the history of Canon Law. He is also most likely the same person as Omnibonus, the author of a theological treatise from about the same period. The theological treatise of Omnibonus shows the influence of the school of Abelard, Hugh of Saint-Victor, Roland, and, of course, Gratian.
