A scarce edition of a masterpiece of a founding text of Canon Law in Middle Ages.

Henricus de Segusio —also called Hostiensis— was the most important and brilliant canonist of the thirteenth century. His works had great influence on the development of canonical jurisprudence and was used extensively by later jurists.After have studied law at Bologna with celebrated teachers like Jacobus Balduinus, Homobonus and Johannes Andrea, he became, in a relatively short time , the most prolific and creative canonist of his age. Apart from a short period in Paris teaching canon law, he did not follow properly an academic career, pursuing contrarily an advancement in the ecclesiastical hierarchy.The Summa is Hostiensis's first systematic work; finished around 1253 while he was archbishop of Embrun, is mainly an exposition of the titles of the Decretals, even if Hostiensis added many titles, some fifty in all, to those of the Liber extravagans of Gregory IX. The primary models for Hostiensis were the Goffredo de Trano's and Azo’s Summae; as his referring sources, he cites in many glosses, famous French theologians as Hugues of St. Cher, William of Paris and Phillip of Aix.
