“Finally, avoid carefully a certain book entitled _Index of Books to be Expurgated_, printed at Madrid by Alphonso Gomez in the year 1584, since we must rather believe the statement false that it was printed in such a city and by the said Alphonso, and also the statement that it was printed and published by the body of the supreme Catholic senate. And among other erroneous or heretical passages contained in it is that which says that some of the works of Carolus Molinaeus, a heretic of the first class, may be permitted without correction.” The editor was not successful in securing for this theory of interpretation the approval of the Inquisition, and was himself, in 1590, brought to the stake at Salamanca as a heretic. Llorente[167] states that at the same _auto da fe_, Torquemada caused to be burned many Hebrew Bibles and six thousand other volumes. CHAPTER XI ROMAN INDEXES AND DECREES, 1590–1661 1. 1590.

The work was completed within two years and was printed in July, 1590, by Paul Bladus. This is the first Index the compilation of which was carried out by the Congregation. It is issued in the form of a Bull with the following title: _Bulla Smi. D. N. Sixti Papae V. Emendationis indicis cum suis Regulis super librorum prohibitione, expurgatione et revisione necnon cum abrogatione caeterorum indicum hactenus editorum, et revocatione facultatis edendorum, nisi ad praescriptam harum regularam normam._ The substance of the Bull may be summarised as follows: Bull of the most revered Lord and Father, Pope Sixtus V, in regard to the production of a revised Index, with which are given the Pope’s regulations concerning the prohibition, expurgation, and revision of books, together with the abrogation of the authority of Indexes previously issued, and the revocation of the authority to print Index regulations other than those herewith presented. The Bull makes reference to the precedents for prohibitory censorship as having been established by Gelasius I and Gregory IX. Reference is also made to the establishment of the Congregation of the Index, by which this responsibility is hereafter to be discharged.
