Antonius de Butrio

Antonius de Butrio (1338–1408), also called Antonio da Butrio (or simply Don Antonius), was an Italian jurist and a teacher of law at Bologna.

Biography Antonius de Butrio was venerated in his lifetime both for his qualities as a professor and for the example of his religious and moral virtues. His university career was essentially at Bologna, where he attracted numerous pupils, among them future great representatives of 15th-century canonical science, like Johannes de Imola, Francesco Zabarella or Domenico di San Giminiano.

He composed numerous commentaries to the Decretals of Gregory IX and the Liber Sextus, which provide a comprehensive impression of the contemporary practice of canon and civil law. In 1408, he also negotiated on behalf of Gregory XII about the end of the Western Schism.
