AZZONE DEI PORCI,

born c. 1150, , Bologna or Casalmaggiore, Italy died 1230 also called Azzone Soldanus, Latin Azolinus Porcius, Azzone also spelled Azo, or Azzo a leader of the Bolognese school of jurists, one of the few to write systematic summaries (summae) rather than textual glosses of Roman law as codified under the Byzantine emperor Justinian I (6th century AD). A professor of civil law at Bologna from 1190, he was a pupil of one noted jurist, Joannes Bassianus, and teacher of another, Franciscus Accursius. Much of the Roman material used by the English jurist Henry de Bracton (died 1268) in his De legibus et consuetudinibus Angliae (On the Laws and Customs of England) was derived from Azzone's summaries. The legal historian F.W. Maitland edited Select Passages from the Works of Bracton and Azo (1895).
