 Father Juan de Zumárraga (1468–1548) founded El Colegio de Tlatelolco, a school in which the natives were instructed in Christian theology and philosophy. He also helped install the first press in 1539, and he conceived the creation of the Royal and Pontifical University of Mexico (the predecessor to the National University of Mexico today). Zumárraga wrote several books that exhibit the influence of Erasmus and of the Spanish humanist Constantino Ponce, who was a chaplain in Charles I’s court and later accused by the Inquisition of being a Protestant.
