James of Viterbo

James of Viterbo ( * 1255, † by 1308 in Naples) was a late medieval theologian and writer.

Jacob went in his early years at the Augustinian order. He studied theology at the University of Paris, where one of his teachers Aegidius Romanus was. From 1293 to 1300 Jacob taught in Paris as a master of theology, from 1300 he headed the general studies in Naples. He was Archbishop of Benevento end of 1302, and shortly afterwards Archbishop of Naples.

Jacob has written several writings are important about his Quaestiones de divinis in praedicamentis, some other works, however, are not preserved. Philosophically was sometimes quite speculative acting Jacob (hence nickname Doctor speculativus ) influenced among other things by Aegidius and Thomas Aquinas. Jacob 's De regimine christiano was written between Philip IV of France and Pope Boniface VIII in the context of the conflict. Jacob took for the Pope party, but in a less severe form than about Aegidius.
