The use for faithful Catholics of available editions of the Fathers had been seriously interfered with by the regulations of the Index of 1559, and even by the modifications of these in 1561. Hosius writes in 1565 to Cardinal Amulius[180] complaining that before Pius V the writings of the Fathers had been brought into print not in Rome or other Catholic cities, but chiefly in centres of heresy like Basel where the editors corrupted the original text. He had tried to make purchase in Rome of the works of Ambrose, Augustine, Jerome, and Gregory, but had been told by the booksellers that the only available editions were prohibited. Such a complaint may be taken as an indication of the greater scholarly enterprise and intellectual activity of the communities which had been influenced by Protestantism. The title-page of an edition of Augustine, printed in Venice in 1570, contains a notice that the text has been carefully revised and freed from all the corruptions and _scholia_ introduced into the previous editions by Erasmus and other heretical and condemned writers. Thomas James[181] points out that the edition of Gregory the Great printed in Rome in 1585 contains no less than 1085 passages in which the text varies from that of the authoritative manuscripts. Calandrini speaks of 13,000 such variations. Reusch is, however, of opinion that these charges of corruptions in Roman editions are exaggerated.[182] _6._ _Expurgations in the Roman Index, 1624–1640._ The Roman Indexes, with the exceptions of that of Brasichelli and the suppressed Index of Sixtus, are classed as prohibitory only. It is the case, however, in certain instances that in place of the term _donec corrigatur_ (usually indicated simply by the letters _d. c._) is given a paragraph in which is specified the material that is to be omitted and the omission of which will leave the book in the list of those permitted. Such a paragraph is, for instance, connected in several of the Roman Indexes with the name Copernicus. Occasionally is connected with the entry of the title and the letters _d. c._ a reference to an expurgated edition published under the authority of the Congregation, the reading of which is permitted. Among authors whose works the value of which is in this way emphasised are Natalis, Bottero, Florentini, Garafalo, Scaramelli, etc. In the case of certain other authors (nearly exclusively Italians) the editors have taken the pains to specify in the Index itself the ground for the prohibition.[183] _7._ _1624–1661._ _Rome._ _Censorship Decrees._ _Index librorum post indicem Clementis VIII prohibitorum decreta omnia hactenus edita._ _Romae, ex typographia Rev.
