 "La Celestina", which was not included in the Indexes of the 16th century, was expurgated in 1632 and prohibited in its entirety in 1790.Among the non-Spanish authors prohibited were Ovid, Dante, Rabelais, Ariosto, Machiavelli, Erasmus, Jean Bodin, Valentine Naibod and Thomas More (known in Spain as Tomás Moro).One of the most outstanding and best-known cases in which the Inquisition directly confronted literary activity is that of Fray Luis de León, noted humanist and religious writer of converso origin, who was imprisoned for four years (from 1572 to 1576) for having translated the Song of Songs directly from Hebrew.
