BARTOLUS OF SAXOFERRATO

born 1313/14, Sassoferrato, Papal States died 1357, Perugia Italian Bartolo Da Sassoferrato lawyer, law teacher at Perugia, and chief among the post-glossators, or commentators, a group of north Italian jurists who, from the mid-14th century, wrote on the civil (Roman) law. Their predecessors, the glossators, had worked at Bologna from about 1125. Bartolus studied law at the universities of Perugia and Bologna and held the chair of law at Perugia from 1343 onward. He and his colleagues used the Corpus Juris Civilis of the 6th-century Byzantine emperor Justinian I and the work of the glossators thereon, together with Roman civil law, as a foundation from which to derive broad legal principles that could be of practical use in 14th-century Europe. Through this process he wrote several extremely influential legal doctrines, particularly those on the governmental authority of city-states and the rights of the individuals and corporate bodies within them. These and other of his principles became the common law of Italy and were also recognized as law in Spain, Portugal, and Germany. Bartolus' commentaries on what came to be called the Code of Justinian were sometimes accorded an authority equal to that of the code itself.
