_In 1566_, _Pius V_ appointed a commission of five cardinals, who associated with them twelve scholars, for the preparation of a new edition of the _Corpus Juris Canonici_. The commission bore the name of _Congregatio de emendatione decreti Gratiani_, and came to be known as _Correctores Romani_. The work appeared in 1582, with two briefs (1580, 1582) of Gregory XIII directing that this edition should thereafter be the sole authority, and prohibiting the printing of it with notes or interpretations. _In 1570_, were printed revised editions of the Book of the Mass and the Breviary. Pius issued a Bull forbidding, under penalty of excommunication, the further printing of liturgies except with special privilege. The Bull permitted, however, the reprinting and the use of liturgies that had been used for not less than two hundred years. Of the Breviary of Cologne, which belonged to this class, an edition was printed in 1576, with a privilege from Gregory XIII.[158] _In 1583_, the famous treatise of Scaliger, _De Emendatione Temporum_, received the honour of a special condemnation from Gregory XIII. Gregory had some years earlier authorised the publication, without the name of the author, of an expurgated edition of the _Adagia_ of Erasmus. In 1575, at the instance of the Congregation, Gregory ordered that all works by heretical authors which had been authorised for publication in expurgated editions should be printed without the names of their authors. CHAPTER X INDEXES OF THE NETHERLANDS, SPAIN, AND ITALY, 1569–1588 _1._ _1569._ _Antwerp._ Index, issued under the authority of an edict of the king: _Philippi II. Regis Catholici Edictum, de Librorum prohibitorum Catalogo observando, una cum iis qui mandato Regiae Catholicae Majestatis, et illustriss. Ducis Albani, consiliiq., Regii decreto, prohibentur, suo quaeq. loco et ordine repositis._ This presents the Tridentine Index with certain titles interpolated, and with some additional lists. The decree of Philip makes reference to the _Taxae_ of the Church of Rome. The wording is _Praxis et Taxa officinae poenitentiariae Papae_. Mendham speaks of a monograph (of which he possessed a copy reprinted from the Paris edition of 1520) entitled _Taxatio Papalis_, being an account of the _Tax-book of the United Church and Court of Modern Rome_, by Emancipatus. He states that Dr. Milner and other Catholic writers had asserted that “this vile book had no existence but in the imagination of heretics”; while Dr. Butler and others had taken the ground that the work was simply a “record of fees of office.”[159]
