Under the heading of “Prohibited Books on Special Subjects,” are classed together works condemned under certain prohibitions of the last half of the 16th century and the first half of the 17th; for instance, works on duelling, and letters or pamphlets in which the so-called laws and rules of duelling are presented. Forbidden also are _Pasquilles_ (broadsides or tractates), printed or written, which make citations from the Scriptures, or which in any fashion “approach too near” to God or to the saints, or to the sacraments or other holy things of the Church. In certain letters addressed to the Inquisitor-General of Spain, Benedict XIV names a number of writers whose works had, on the ground of special consideration for the authors, been spared from the insertion in the Index, although they had fully deserved such measure of condemnation. Among the books so specified are those of the Pope’s friend, Ludovico Antonio Muratori (1672–1750). When this letter of the Pope with reference to Muratori was made public, the latter wrote to the Pope for some specification of the grounds for the condemnation of his writings. The Pope replied that he had had in view in this reference, not the theological writings of his friend, but the treatise on the civil jurisdiction of the Pope in the papal States. A number of the writings of Muratori came into sharp criticism and were the subject of controversy, but although these were thoroughly investigated and formally denounced in Rome, no one of them finds place in the Index. In the list of authors is retained the name of Poza for his complete works, in continued antagonism to the approval of these works by the framers of the Spanish Indexes. Another noteworthy entry is that of the _Bibliothèque Janséniste, ou Catalogue Alphabétique des Livres Jansénistes, Quesnellistes, Baganistes ou Suspects de ces Erreurs_ (Decr., September 20, 1749). This is the work that supplies the material for the anti-Jansenist appendix in the latest Spanish Index. Its condemnation here constitutes a fresh instance of the antagonism which continued in regard to literature and in regard to certain points of doctrine as presented in literature, between the Church of Rome and the Church of Spain. Raynaud, whose work had been prohibited in the preceding Index, had added his protest to that of Poza at the injustice of being condemned unheard. In his _Genitus Columbae_, is printed as a parody on the methods of the censors, a critique on the Apostles’ Creed in every article of which is discovered some latent and insidious heresy. The work was itself, naturally enough, promptly condemned.[29]
