IRNERIUS

also spelled Guarnerius, or Warnerius born c. 1055, , Bologna died , in or after 1125 one of the scholars who revived Roman legal studies in Italy and the first of a long series of noted legal glossators and teachers of law (late 11thmiddle 13th century) at the University of Bologna. Originally a teacher of the liberal arts, Irnerius studied law in Rome at the insistence of Countess Matilda of Tuscany, who later employed him on diplomatic missions, as did the Holy Roman emperor Henry V. He is believed to have delivered his first law lectures at Bologna about 1088 and to have taught Bulgarus, the most prominent of the second generation of Bolognese glossators. Irnerius' most ambitious work was an annotation of the Corpus Juris Civilis of the Byzantine emperor Justinian I (reigned 527565).
