=18. Controversies concerning the Chinese and Malabar Usages.=--Under Clement XI, was decided, adversely to the contentions of the Jesuits, through a decree of the Inquisition in 1710 and a Bull of 1715, an issue that had continued during a series of years between the missionaries of the Jesuits and those of the rival Orders, concerning the propriety of permitting the Chinese converts to retain certain special usages. The Inquisition prohibited the publication, unless with the special authorisation of the pope, of all writings which were concerned with these Chinese usages or with the controversies that had arisen concerning them. This prohibition was entered by Benedict XIV in the _Decreta Gen._, iv, 6, and, in 1722, the division of the great history of the Jesuits by Juvencius, which treated of this matter, was condemned separately. This action aroused fresh controversies and, in 1742, Benedict found occasion for a further Bull devoted to them. In 1744, another Bull was issued, in which decision was given in an analogous issue that had arisen with the Malabars; and, in 1745, Benedict caused the Inquisition to prohibit, on the ground of some antagonistic opinions expressed in it in regard to this decision, a comprehensive history by the Capucin Norbert. The two controversies continued during a long term of years and produced a mass of controversial publications, but few separate titles of these writings came into the Index; the See appears to have considered the general prohibitions above specified sufficient to meet the requirements. =19. Fraudulent Literature.=--In the _Decreta Gen._, ii, 10, are prohibited all books, pamphlets, criticisms, and commentaries, whether written or printed, which had to do with certain lead tablets (_Laminae plumbeae_) which had been dug up in Granada and which bore ancient Arabic characters; with these were condemned certain manuscripts which had been unearthed in the foundations of an old tower in Granada. The condemnation covers also works not devoted to this subject-matter but in which references are made to said tablets or writings, until and unless such references have been eliminated. The fragments of tablets and of manuscripts, which, according to their text, had been inscribed in the time of the Apostles, were discovered between the years 1588 and 1597; but it was not until 1682 that they were officially pronounced by the authorities in Rome to be fraudulent. The false monographs of Flavius Lucius Dexter which belonged to the same group of manufactured documents, were never forbidden either in Rome or in Spain. Of the long series of treatises written concerning the letter said to have been addressed by the Madonna to the residents of Messina, two only have come into the Index.
