_Index librorum ... comprobatus. Nunc recens de mandato Illust. ac Rev. D. George Dalmeida, Metrop. Archiep. Olyssipon. totiusque Lusitanicae ditionis Inquis. General. in luce editus. Addito etiam altero Indice eorum Librorum qui in his Portugaliae Regnis prohibentur, cum permultis aliis ad eandem Librorum prohibitionem spectantibus, ... Olyssipone, excudebat Antonio Reberius._ The edict of the Inquisition announces the imposition of the penalty of the _excommunicatio latae sententiae_ for any disobedience of the regulations. The new lists comprise about 160 titles. A number of these new titles became of more than local importance as they were taken over by Quiroga and also by Sixtus V. The work of the Lisbon compilers was in part based upon Valdes. Among the new names may be noted: Jerome Cardan, Georgius Venetus, Crinitus and Amatus Lusitanus. Ariosto’s _Orlando Furioso_, Bocardo’s _Orlando Imamorato_, and Dante’s _Divine Comedy_ are grouped together in Class II. These three titles were, however, not repeated by the compilers of Sixtus. The _Utopia_ of Thomas More and the _Praise of Folly_ of Erasmus are placed together in Class II. Quiroga, in repeating the _Utopia_, places it with books to be permitted if corrected. _6._ _1583._ _Madrid._ _Inquisitor-General Quiroga._ In 1583, the Inquisitor-General Quiroga, on the strength of his apostolic authority, orders the preparation of a new catalogue of prohibited books. The edict states that, by reason of the great increase and wide circulation of heresies, the catalogues heretofore published are no longer sufficient. The Inquisition has therefore determined to prepare a new and comprehensive list of books which have been condemned, and with such lists to publish a series of general authoritative regulations for the control of the printing and the reading of books. Quiroga utilised for the compilation of the Index representatives of the three universities and a number of other scholars. The regulations prohibit, under the penalty of the _excommunicatio latae sententiae_, the reading or the possession (either in bookshops or in private collections) of the books specified, or of any books containing the pernicious and heretical doctrines described in the general classification. To the secretary of the Inquisition, as consideration for his labour in the compilation of this Index, were assigned the “rights” for its publication. It may well be doubted, however, whether this publishing privilege brought to the secretary any very substantial return; as excepting in the case of the Tridentine, no one of the series of Indexes appears to have secured any remunerative sale.
