ABSTRACT
Enrico da Susa (in Latin Henricus de Segusio) influenced European jurisprudence until the seventeenth century. His Summa and Lectura became standard works that later jurists cited constantly. Both works circulated widely into the far reaches of Europe. When they were printed in the fifteenth century they were exported to the New World as well. He taught briefly at Paris but spent most of his life in higher ecclesiastical offices. After holding several lower offices in southern France, he became the bishop of Sisteron. Pope Urban IV elevated him in 1262 to the cardinal bishopric of Ostia. From that time on he and his works were referred to only by his title as cardinal, Hostiensis. For many he represented the archtypical medieval jurist. Dante picked him to contrast to medieval theologians whom he admired.
