Biography/Description

J. is known to have studied at Modena under, among others, Hubertus de Bobbio, c. 1235 X 1237. From 1237 to 1263 he is found at Marseille where he practiced as an advocate and also served as a judge for the commune. He gave counsel in feudal matters to the bishop of Marseille, and was the ambassador of the city to the first council of Lyons (1245) and to Charles of Anjou, the count of Provence. Charles exiled him from Marseille in 1263 because of J’s support of the revolt of Marseille against him. J. is last found in 1267–8 at Montpellier in the service of Charles’s enemy, Jaume I, the king of Aragon.

J.’s Summa feudorum (TUI 1584, t. 10.1) was written in Marseille sometime between 1246 and 1263. It relies heavily on the work of the same name by Jacobus de Ardizzone, but also makes reference to J’s own practice experience. A treatise, Tractatus de officio executorum ultime voluntatis, written while J. was in exile at Manosque (dép. Alpes-de-Haute-Provence) in 1263, remains in manuscript.
