_7._ _1549._ _Venice._ _Il catalogo de’ Libri li quali nuovamente nel mesi di maggio nell anno presente MDXLVIIII, sono stati condannati et scommunicati per heretici, da Giovan della Casa, legato di Venetia et d’Alcani frati. E aggiunto sopra il medesimo catalogo un judicis et discorso del Vergerio, 1549._ (In dating this Index 1549 instead of 1548 as stated by Reusch, I take the authority of Mendham, who cites the _catalogus Bibliothecae Banavianae_.) This Index is known by the name of Casa. No copies of the original have been found, and the references to it are based upon the reprint issued by Vergerio in 1550. John della Casa was the Archbishop of Benvenuto, and papal Nuncio at Venice. His Index was, according to Vergerio, prepared by the command of Pope Paul III. It must in that case take rank as the first Index issued under direct papal authority. The lists are preceded by the statement that: “All works produced by the heretics and heresiarchs whose names follow, which have to do with theology or kindred subjects, are condemned and prohibited.” The names of authors include Luther, Huss, Marsilius of Padua, and Nicholas Clemangis. The catalogue presents 142 titles--of which twenty-five are those of books issued (in Latin) anonymously. There is also a general prohibition of “Bibles and New Testaments containing notes or comments opposed to the faith, and of all works which within the preceding twenty-four years have been printed without the name of the author and address of the printer.” Vergerio is able to point out that this Index is a very clumsy compilation which contains a full measure of errors and which compares unfavourably with the catalogues recently issued in Louvain and in Paris. In certain instances, the names of the authors or of their books are so carelessly worded as to render identification difficult. The titles of a number of the Latin books are given in Italian, and those of some of the few Italian books in Latin. There does not appear to be any arrangement of the titles, alphabetical or other. Of certain authors, as, for instance, of Giusto Giona, all the writings are condemned, and later are given for separate condemnation the titles of selected books of the same author. Casa speaks of having secured the assistance of some of the most learned of the Italian theologians, but their work appears to have been most carelessly done, particularly in view of the fact that they had available for use the comparatively accurate lists of the Louvain Catalogue of 1546.
