 Although most accounts of Latin university philosophy tail off in the mid-fourteenth century, this style of philosophizing continued vigorously for at least three centuries  (§5.2),  and in this period universities were established all over Europe. Late in the fourteenth century, John Wyclif (d. 1384), trained at Oxford, elaborated a sophisticated and idiosyncratic system of philosophy and theology, aspects of which were taken up by  Paul of Venice  (d. 1429), the greatest logician of his time. The Arts Faculties of Italian universities flourished especially in the late fifteenth and sixteenth centuries;  Pietro Pomponazzi  (1462–1525) was the most famous of these teachers, and the most audacious in defending the prerogative of Arts Masters to expound the genuine thought of Aristotle, whatever its differences from Christian doctrine  (§3.3).  This tradition of university philosophy continued for nearly two more centuries, with thinkers like  Giacomo Zabarella  (d. 1589) in Italy and a host of important figures in Spain and Portugal  (§5.2).
