Biography/Description

The youngest of the ‘Four Doctors’. Most likely from Bologna from a Lombard family; documented as a lawyer and teacher of law in Bolognese sources between 1151 and 1169; in the first document, the first podesta of Bologna named him judge delegate; in this final date he represented the abbey of Pomposa before the bishop of Bologna acting as a papal judge delegate. Probably active for a time in Modena. Student of Irnerius; probably also studied under Bulgarus and Martinus. Came into the service of Frederick Barbarossa in 1155 with Bulgarus and Martinus and was consulted at Roncaglia in 1158. Died on 11 October,1178, survived by at least one daughter, Zugiana.

J. maintained a very good reputation in his day. Later sources indicate that he was involved in writing certain of the Roman law sections of the Decretum, but whether this is true or how exactly Jacobus was involved is unclear. Fewer writings of his have survived and been printed than those of Bulgarus and Martinus. He is cited far less in the Glossa ordinaria (about 30 times). Unique at his time for his interest in the final three books of the Codex (the Tres Libri). Probably had foremost interest in criminal and procedural law. His glosses bear the siglum ‘J’, ‘Ja’, or ‘Jaco’.
