Class I constitutes a large division in the Quiroga Index. The compilers find deserving of condemnation the entire works of a number of authors of whose writings only single books appear in the Tridentine lists. It was probably less troublesome to put an author once for all in the class of heretics than to incur the labour of examining all of his productions. In Class II, I may note the name of Theophrastus Paracelsus (1541) connected with his _Libri tres Chirurgiae_. One of the three books was permitted in the expurgated edition. In later Indexes, Paracelsus is reproved because his writings contain so many magic and cabalistic names which are hardly to be understood. _8._ _1588._ _Naples._ _F. Gregorius Capucinus._ In 1588 was published at Venice a handbook for confessors, prepared by F. Gregorius, a Capucin monk. It bears the title: _Enchiridion Ecclesiasticum sive Praeparatio pertinens ad Sacramentum Poenitentiae et Sacri Ordinis, Editum a R. P. F. Gregorio Capucino Neapolitano uno ex Deputatis Patribus pro Revisione Librorum in Civitate Neapolitana ... cum Privilegio S. Fran. Inst. Regu. Fr. Min. Venetiis ... H. Polo Typographo Venito imprimente_. The volume possesses no official character, but is referred to by Mendham[166] as important because of its references to forbidden and expurgated books. Gregorius takes occasion to caution his readers against the _Index expurgatorius_ of Quiroga as unsound, because Quiroga fails to condemn the works of Molinaeus and Raymond Lullus, and does not make sufficient excisions in the _Practica Papiensis_ of Petrus de Ferrariis. In the succeeding Spanish Indexes, we find, as might be expected, a condemnation and prohibition of the _Enchiridion_ of Gregorius. This Naples Index is described as very scarce. A copy is, however, contained in the Bodleian Library in Oxford. The catalogue or Index forming the second division of the work begins on page 146 under the title of _Libri Corrigendi_. The preface to the catalogue makes clear its connection with the general subject of the work. It begins as follows: _Quomodo Confessor potest cognoscere, si poenitens tenetur ad aliquot placatum, ob lectionem librorum, qui sunt a Catholicis editi, sed sunt infecti et prohibiti ob interpositionem haereticorum, qui se interposuerunt indictis libris, et aliorum qui sunt adnotati et prohibiti in Indice Romano vel Tridentino.... Hoc potest cognosci ex sequenti lista; sed est quaedam adnotatio, sive memoria edita, A. M. R. D. D. Johanne Franciso Lombardo_, etc. _Post longum studium contra libros haereticorum._ Capucino adds, after presenting his list:
