 The letter written in 1295 by Peter of John Olivi to Conrad in which the legitimacy of Boniface VIII's election is defended, has been edited by Ignatius Jeiler (Historisches Jahrbuch, III, 649).During a course of missions he was giving at Bastia in Umbria, he died on 12 December 1306 at the age of about sixty-five years and was buried in that place.Fifty-six years later his remains were carried off by the Perugians and buried at San Francesco in the Oratory of San Bernardino, reposing beside those of Giles of Assisi in the choir of the cathedral at Perugia.
