Book excerpt: In Cum essem in Constantie, Martin John Cable presents a study of the Padua university jurist Raffaele Fulgosio (Fulgosius) (1367-1427) and his work as an advocate at the Council of Constance in 1414-15. Through the use of archival material and evidence drawn from Fulgosio’s works, the book reveals a vivid picture both of teaching practice at a medieval university and the life and output of a working lawyer in early fifteenth-century Italy. The book recreates much of Fulgosio’s workload at Constance and his involvement there in debates about representation, imperial and papal power and the Donation of Constantine.
