Irnerius

He taught the newly recovered Roman lawcode of Justinian I, the Corpus Juris Civilis, among the liberal arts at the University of Bologna, his native city.

[1] Irnerius taught along lines firmly established in the teaching of Scripture, by reading aloud a section of the civil law, which the students would copy, and add to the text his commentary and explanatory glosses.

According to ancient opinion (which, however, has been much controverted), Irnerius was the author of the epitome of the Novellae of Justinian, called the Authentica, arranged according to the titles of the Code.

Irnerius was largely forgotten until his name was revived by German historians of the later 19th century and came to prominence with the celebrations marking the octocentennial of the University of Bologna.

[7] Anders Winroth has questioned much of the received account of Irnerius' life as well as his importance to the history of Roman law in the Middle Ages.
