He studied under
Baldus de Ubaldis at
Perugia, and was a fellow-pupil with
Cardinal de Zabarella. He was admitted to the degree of doctor of civil law in the
University of Avignon, but it is uncertain when he first undertook the duties of a professor. A tradition, which has been handed down by
Panzirolus, represents him as having taught law for a period of fifty-seven years. He was professor at
Siena in 1390, at
Avignon in 1394, and at
Padua in 1429; and, at different periods, at
Florence, at
Bologna and at Perugia. He was for some time the vicar-general of Cardinal Zabarella at Florence, and his eminence as a teacher of
Canon law may be inferred from the appraisal of one of his pupils, who styles him
famosissimus juris utriusque monarca. His most complete treatise is his readings on
the Digest, and it appears from a passage in his readings on the
Digestum Vetus that he delivered them at a time when he had been actively engaged for forty-five years as a teacher of civil law. His death is generally assigned to 1436, but it appears from an entry in a manuscript of the
Digestum Vetus, which is extant at
Munich, made by the hand of one of his pupils who styles him
præceptor meus, that he died on 20 July 1441. == Works ==
