1911 Encyclopædia Britannica/Petrus Aureolus

PETRUS AUREOLUS (Oriol), scholastic philosopher and monk of the Franciscan order, lived in the latter half of the 13th century, and died in Paris in 1321 just after his appointment as archbishop of Aix. He was one of the first to attack the realist doctrines of Duns Scotus, and is interesting mainly as the precursor of William of Occam in his revival of Nominalism. His ability earned for him the titles of Doctor Facundus and Doctor Abundans.
