Pere Daguí (1435-1500) probably received his intellectual training in Barcelona. In 1481, he moved to Majorca to lead the new school of Lullian studies, which soon after was elevated to the status of a university. In 1484, Daguí left for Rome in order to defend the Catholic orthodoxy of his Lullist work Ianua artis. Probably while in Rome, he also drafted a short treatise on the concept of difference, a topic which he also treated in later writings. In his discussions of this topic he borrowed elements from both the Lullist and the Scotist traditions. He spent the last part of his life at the itinerant court of the Catholic Monarchs, Isabella and Ferdinand, returning to Majorca only shortly before his death. The Lullian institution he had lead continued to cultivate his eclectic approach and held philosophical and theological chairs «ad mentem Scoti» until the beginning of the 19th Century.
