He studied Roman and ecclesiastical law at Bologna, where he himself became a teacher.
It is believed that he was murdered, when Ezzelino, the leader of the Ghibellines, captured Brescia (1258).
His "Brocarda", or Canonical Rules (Lyons, 1519), were a working-over of those of Damasus (12th and 13th centuries);[1] his "Casus decretorum" were a revision of the "Casus" of Benencasa (d. c. 1206); the "Historiae super libro Decretorum" reproduced the work of an unknown author.
Both his "Casus" and "Historiae" derive their importance from their incorporation into the Paris edition (1505) of Gratian's Decretum.
His only certain independent work was the "Quaestiones dominicales et veneriales", lectures delivered on Sundays and Fridays.
