Bartolus of Sassoferrato was a prominent Italian legal scholar born around 1313 in Sassoferrato, Italy. He is best known for his influential commentaries on Roman law, particularly the Corpus Juris Civilis, which laid the foundation for modern legal systems in Europe. His work helped to revive interest in Roman law during the late Middle Ages. Bartolus served as a professor at the University of Perugia and became a key figure in the development of the glossators and commentators schools of legal thought. His writings emphasized the importance of legal interpretation and the application of law to contemporary issues, shaping the study of law for generations.
