Abstract
Antonius Andreae (ca 1280 – ca 1333) is an important figure in the early development of Scotist school but also an obscure one, known mostly for his professed fidelity to the doctrine of his Parisian teacher, John Duns Scotus. The analysis of his surviving texts reveals (scant) information that allows for establishing a chronology of his most important works: De tribus principiis naturae, the commentary on the Metaphysics, the commentary on the Ars Vetus, and the Abbreviatio operis oxoniensis Scoti, as well as a (partial) reconstruction of his academic life after the return to his native Aragon from Paris. It also shows Antonius as a fierce opponent of Peter Auriol, whose views he finds to be especially repugnant to the teaching of Scotus
