Biography/Description

One of the most eminent of the thirteenth-century decretalists who combined his accomplishments as a jurist with an equally successful ecclesiastical career. Born around 1200, he studied law at Bologna in the 1220s, at about the same time when Sinibaldo dei Fieschi, the future pope Innocent IV (1241–54), began his training as a lawyer there. It remains uncertain whether Hostiensis ever taught in Italy. By 1239, he was apparently archdeacon of Paris and may have taught on the Gregorian decretals, whereas other sources relate his long stay in England (1236?–44) as a member of the household of Queen Eleanor. Simultaneously, his relationship to the the papacy grew very close, and Henry soon served as Pope Innocent’s chaplain. He received the bishopric of Sisteron in 1243–1244, and later became archbishop of Embrun (1250–61). The pope repeatedly employed him in diplomatic missions. His efforts were finally rewarded with the cardinalate, which Pope Urban IV bestowed upon him in 1262 in the form of the bishopric of Ostia, from which his later name of Hostiensis comes. He participated in the protracted conclave at Viterbo (1268–70), but illness forced him to leave before the final election took place. When he died in the Dominican convent at Lyon (1271), he had just completed the second version of his Lectura on the Decretales Gregorii noni. Among his earlier works, the Summa on the Decretales, completed c.1253, was even more celebrated. Since the early days of printing, this work came to circulate with the epithet aurea (first in ed. Rome 1473). Henry also published a Lectura on the first two collections of Novelle promulgated by Innocent IV (1245/46), to which he added several later decretals (before Sept. 1253).

 

Text(s)

 
No. 1

Summa, c. 1253. The manuscripts reflect three stages of development, in one of which the Quaestio (Text 5) is not inserted or attached, in one the Quaestio is attached at the end (cf. the list provided by M. Bertram, BMCL 16 (1986) 96–97), and in one the Quaestio is inserted under the title De sententia excommunicationis. All printed editions seem to reflect this last version.

 
No. 2

Lectura on the Novellae I–II of Innocent IV.

 
No. 3

Lectura on the Decretales Gregorii noni.

 
No. 4

Decretum electionis, after 1253.

 
No. 5

Quaestio, post 1261. written by Hostiensis while he was at the Roman curia, upon a request from the University of Bologna (after 1261).
