Alternative Names




Jurist and judge active in Bologna from 1154 to 1177. Possibly served as legal counselor to Eugenius III (1145–53); also documented in Modena. Lange has doubted his teaching activity and attributed his designation ‘magister’ as a title indicating that he never achieved the stature of ‘doctor’. Others have suggested the title indicates that he taught canon as well as civil law. His canonistic activities we know only indirectly, however, through the references of other canonists (Egidius, Huguccio) of the 1180s. He enjoyed a high reputation among later glossators even though no self-standing work attributed to him survives and he is cited far less frequently than others in glosses and the Dissensiones dominorum. He is referred to by his full name or with the siglum ‘Ald’ or ‘Aldri’.
