Timeline

1. c. 1088–1220University of Bologna · BolognaScholars such as Irnerius taught Roman law at Bologna through interlinear glosses, drawing students from across Europe and establishing the earliest university law curriculum, thereby founding the glossator school.
2. c. 1220–1260Bologna · BolognaAccursius completed the Glossa Ordinaria on the Digest, bringing the glossator tradition to its peak; his glosses, later called the Accursian Gloss, became the authoritative text cited by medieval courts applying Roman law.
3. c. 1260–1400Italian and European universities · ItalyPost-glossators such as Bartolus and Baldus turned to systematic treatises and practical commentaries; Roman law teaching spread to Padua, Paris, and elsewhere, influencing canon law and royal legislation.
4. c. 1400–1800Continental Europe · EuropeRenaissance humanist jurists criticized the purely glossatorial tradition, yet the Roman law conceptual system established by the glossators profoundly influenced the codification of modern civil codes such as the Napoleonic Code, forming a core source of the civil law tradition.
