The Index of Clement bears to that of Sixtus a relation similar to that borne by the Index of Pius IV to that of Paul IV; but a larger portion of the Sistine lists was cancelled by the Clementine compilers. The order of arrangement follows that of the Index of Trent, the new names and new titles being brought in as appendices at the close of each class, and as additions after each letter. The Ten Rules of Trent are repeated with the addition of certain “observations” in regard to translations of the Scriptures, works on astrology, the _Talmud_ and other Jewish writings. The most distinctive addition to the regulations is an instruction placing in the hands of the bishop and inquisitors (or in Rome in those of the _Magister S. Palatii_) the responsibility for the prohibition or expurgation of books that were already in print, and for the examination of writings for which a printing license was issued. In the brief printed as an introduction, the Pope confirms the powers, privileges, and instructions given by Pius V, Gregory XIII, and Sixtus V to the _Magister S. Palatii_ and to the cardinals of the Congregation. The brief goes on to state that in the case of any questions or controversies arising in regard to the interpretation of the rules and regulations as supplemented, these shall be passed upon by the Congregation, or in matters of special moment shall be referred to the Pope. The Index of Clement is the only papal Index which, before coming into publication, secured the advantage of consideration from various points of view and of a revision extending over three years. The Venetian ambassador, writing in January and again in March, 1594, makes reference to a number of protests that had been submitted, on behalf of the scholars and publishers of Italy, in regard to the long list of additions to the Index of Italian works. It would appear that the Pope took a more liberal view of these Italian writings than that expressed by the work of the Congregation. Baronius, writing in July, 1593, to Lipsius, reports that the Pope had found it necessary to disapprove the lists as prepared, although these were already in print. Bellarmin, writing late in the same year, explains that his other duties had compelled him to be absent from many of the sittings of the Congregation. He appears to desire to make clear that the errors of judgment complained of did not belong to his responsibility. In the schedules as finally approved, Clement omits from Class I, as first shaped by Sixtus, fifteen names; the only one of these which may be considered as of continuing interest is that of Paracelsus. The additions to this class comprise twenty-five names. Among these are included a number of Englishmen, such as Matthew Parker of Canterbury, Matthew Hutton of York, William Fulke, and John Knewstub.
