Huguccio. Hugh of Pisa, a distinguished Italian canonist, who died in 1210. He was born at Pisa, but the date is unknown. He studied at Bologna, where later he professed Canon Law. In 1190 he became Bishop of Ferrara. Among his works are a Liber deruationum which treats of etymology. He also wrote a Summa on the Decretum of Gratian, which has been considered the most extensive and one of the most valuable commentaries of the time. There are, however, certain omissions, but these gaps were filled by the industry of Joannes de Deo.
