The prohibition issued by Alexander in decree number IV with the title: _Instructionum et rituum sectae Mahumetanae libri omnes_, seems to have had for its immediate text a work entitled: _Liber de Russorum, Moscovitarum, et Tartarorum religione_, which was printed at Spires. In the Index of Benedict, the title was for the first time given complete with the name of the author, Lasitzki, Jo., _de Russorum rel. sacrificiis, nuptiarum et funerum ritu e diversis scriptoribus_. Under the general prohibition of bibliographical works in which any terms of approval are connected with the names of heretical writers, is included (in 1687) the following English work: Crowaei Guil, _Elenchus scriptorum in s. scripturam tam graecorum quam latinorum_, London, 1672. A work of similar character, compiled by Thomas Pope Blount, under the title _Censura celebrium auctorum_, printed in London in 1690, escaped the attention of the compilers. =2. Book Prohibitions by the Bishops.=--During the 17th and 18th centuries, were published no lists of books condemned under the authority of the bishops which compare in importance or in influence with the Indexes issued during the 17th century from Louvain and from Paris. During the 17th century, however, there are a number of instances of individual books condemned by the divines of the Sorbonne, of Louvain, and of other theological faculties. One Index of some comprehensiveness was issued by the Archbishop of Paris, but the work was undertaken at the instance of the Parliament. Two Indexes were issued by the Archbishops of Prague, and the decree of Precipiano, Archbishop of Utrecht, has already been referred to. As late as the last half of the 18th century, the bishops have utilised the form of pastoral letters and pastoral instructions for the condemnation of individual books and, occasionally, of lists of books. A pastoral letter, for instance, of the Vicar-General of Augsburg, issued in 1758, presents a list of fifty-five works which are condemned on the ground of their association with the “new sects and new teachings of mystics and fanatics.” In 1752, similar lists were connected with a decree of the Bishop of Turenne and a pastoral instruction of the Bishop of Luçon.
