In 1749, was printed at Prague a second and enlarged edition of this _Clavis_. In 1767, the Archbishop of Prague, Przichovsky, printed, in obedience to an encyclical of Clement XIII, an Index presenting Bohemian books only. The title is: _Index Bohemicorum librorum prohibitorum et corrigendorum et ordine alphabetico digestus_, etc. In the _Clavis_ of 1729, the _Index prohibitorius_ is arranged in three alphabeted divisions, the first including the works in Czech, the second those in German, and the third the Latin titles, with which are certain in French. Following each division, are given certain blank pages left for the description of further books. In the second edition is given a special division entitled _Index librorum Veneria vel obscoena tractantium_, presenting a list of works the obscene character of which can fairly be inferred from their titles. It is noteworthy that this very legitimate division of censorship, which received very little attention either in Rome or in Spain, should have been cared for in Bohemia. Beneath the titles of the books in the list for expurgation, are given as a rule brief analyses constituting what might be called a _catalogue raisonnée_, for instance, _perstringuntur religiosi Societatis Jesu_, etc. Against such a name as that of Huss is added the term “heretic” or “arch-heretic.” The compiler of the _Clavis_ was a Jesuit, Anton Koniasch. Koniasch left at his death (in 1760) materials for a further Index which were utilised as the basis of the Index printed in 1767 by Przichovsky. The title proposed by Koniasch was: _Index librorum perniciosorum abolendorum vel repurgandorum_, etc. In the Index as published by the Archbishop, is the order that his pastoral brief, together with the encyclical of the pope, shall, within three weeks’ time, be read on the Sunday in all German and Bohemian churches, and that, on the same day, a sermon shall be given devoted to the danger of heretical books. He orders further that whoever shall be convicted of reading heretical or prohibited books shall _ipse jure_ come under excommunication. This is followed by an edict, issued by Charles VI and confirmed in 1749 by Maria Theresa, in regard to the distribution of heretical books. This Index is both prohibitory and expurgatory, but the two sets of titles are arranged in one alphabet. It contains also an enlarged edition of the Bohemian division of the _Clavis_. =4. Editions of the Roman Indexes, 1670–1800.= _1670._ _Rome._ _Clement X._ In 1670, under the instructions of Clement X, Fanus prints an Index which contains the lists of Alexander and of Clement, with an appendix bringing the record of prohibitions down to date. This volume is again printed in 1675, with an appendix covering the prohibitions of five years.
