Certain general prohibitions are included in the Clementine Index. In the earlier years of the 17th century, further similar prohibitions or decrees are published. In 1621, for instance, is printed the series of decisions of the Congregation of the Council of Trent. The Pope had prohibited the publication of any unauthorised translations of the decrees of Trent, but the above work, carrying with it no authorisation, does not find place in the Index lists. In 1601, appears a prohibition of all litanies with the exception of the Laurentian and that bearing the name of All Saints. In 1603, appears a general prohibition of all writings concerning the Mohammedan religion. In 1633, a decree of the _Magister S. Palatii_ prohibits all _Elogia Haereticorum_. With this prohibition, is included a condemnation of all pictures or medals in honour of heretics. This general prohibition was interpreted to bring into condemnation a long series of important bibliographical works in which had been printed, either with approval or without condemnation, the names of heretical writers. In April, 1621, an announcement was made, on the part of the Congregation of the Council of Trent, protesting against the publication, nominally under the authority of the council, of so-called collections of the declarations of the council, and pointing out that such publications had been specifically condemned under the Bull of Pius IV. With the authority of Gregory XV, all such collections or reports of the decisions and conclusions of the council, issued without specific authority of the council, which had thus far been printed or which should later come into print, were condemned and prohibited. Among the works included under this condemnation, were a number which had been prepared by orthodox Catholic theologians and canonists, such as Prosper Farinaccius, Vincenzio de Marzilla, etc. In the course of the 17th century, the Congregation of Rites condemned a series of prayers and litanies. Reusch states that “up to the present day” (he is writing in 1884) only one such litany, that described as “In the name of Jesus” had secured approbation. The general decree of 1601 prohibiting litanies has never been recalled; and under this decree stand condemned and prohibited all books of service which contain other than the two, or at this time, the three brief litanies. This decree, would, according to Reusch, prohibit nine tenths of the service books in use in the Catholic Church.
