del Castillo. 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. Some scholars state that one of the main effects of the inquisition was to end free thought and scientific thought in Spain. As one contemporary Spaniard in exile put it: "Our country is a land of pride and envy ... barbarism; down there one cannot produce any culture without being suspected of heresy, error and Judaism. Thus silence was imposed on the learned." For the next few centuries, while the rest of Europe was slowly awakened by the influence of the Enlightenment, Spain stagnated. This conclusion is contested. The censorship of books was actually very ineffective, and prohibited books circulated in Spain without significant problems. The Spanish Inquisition never persecuted scientists, and relatively few scientific books were placed on the Index. On the other hand, Spain was a state with more political freedom than in other absolute monarchies in the 16th to 18th centuries. The apparent paradox gets explained by both the hermeticist religious ideas of the Spanish church and monarchy, and the budding seed of what would become Enlightened absolutism taking shape in Spain. The list of banned books was not, as interpreted sometimes, a list of evil books but a list of books that lay people were very likely to misinterpret. The presence of highly symbolical and high-quality literature on the list was so explained. These metaphorical or parable sounding books were listed as not meant for free circulation, but there might be no objections to the book itself and the circulation among scholars was mostly free. Most of these books were carefully collected by the elite. The practical totality of the prohibited books can be found now as then in the library of the monasterio del Escorial, carefully collected by Philip II and Philip III. The collection was "public" after Philip II's death and members
