Irnerius

Irnerius, the 'Lucerna Juris,' a learned jurist of the 12th century, who was born in Bologna, flourished there as a teacher of the liberal arts, and died under the Emperor Lothair II. before 1140. One of the earliest to devote serious study to the Institutes and Code of Justinian, he has been (some think without reason) regarded as the founder of the Bolognese school of law. We possess by him some unprinted Glosses, and the so-called Authentica, an epitome of the Novells of Justinian. His Formularium Tabellionum, a directory for notaries, and his Questiones are now not extant. His name also occurs in the forms Guarnerius, Warnerius, &c. See the monograph by Vecchio (Pisa, 1869), and the 3d vol. of Ficker's Forschung. zur Reichs-u. Rechtsgesch. Italiens (Innsbr. 1870).
