'''Irnerius''' ({{Circa|1050}} – after 1125), sometimes referred to as ''lucerna juris''<ref name=EB1911>{{EB1911 |inline=y|wstitle=Irnerius |volume=14 |page=796}}</ref> ("lantern of the law"), was an Italian [[jurist]], and founder of the [[School of Glossators]] and thus of the tradition of [[medieval Roman Law]].

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. The recovery and revival of Roman law, taught first at Bologna in the 1070s, was a momentous event in European cultural history. Irnerius' [[interlinear glosses]] on the ''Corpus Juris Civilis'' stand at the beginnings of a European law that was written, systematic, comprehensive and rational, and based on Roman law.
