=1. Writings concerning the Papacy and the Inquisition, 1600–1757.=--The Index contains but few of the polemic writings of this period against the Papacy. A few however of the historical works on the Papacy, both by Protestants and Catholics, were prohibited. The lists include a treatise of the Jesuit Riccioli on the infallibility of the pope, but this is entered with a _d.c._ The lists include also a group of writings on the Inquisition, on the Index itself, on the finance system of the papal chancellery, etc. Among these are some monographs by Gregorio Leti (1630–1701), whose entire works secured condemnation in 1686. Reusch points out that the history of the Papacy by Archibald Bower, which was first published in 1748 in seven volumes, and of which a number of editions appeared later, was overlooked by the Index compilers. Bower was born in Scotland, but, becoming a Jesuit, had held a professor’s chair in Italy in Fermo and in Macerata. In 1726, he left Italy and became a member of the Church of England. His treatise was of a character that might naturally have met criticism on the part of the Congregation. The _History of the Inquisition_ by Limborch, printed in Brussels, in 1693, was promptly prohibited in 1694. In the same list, are included the titles of a number of less important treatises on the Inquisition. =2. Writings concerning the Churches of the East.=--The Index lists of the 17th and 18th centuries contain but few of the works of the Greek theologians. Among the authors of this group are to be noted the names Lukaris, Nektarius, Philippus Cyprius, Catum Syrittus, and Sylvester Syropoli. Robert Creighton, professor in Cambridge, later Bishop of Bath, had printed in The Hague in 1660 the _Vera Historia_ of Syropoli, a record of the relations between the Greek and the Latin Church, which includes an account of the Council of Florence. This was prohibited in 1682. =3. Patristic Writings and Pagan Classics.=--During the 17th century, a number of editions of the writings of the Fathers are placed on the Index on the ground of the notes and commentaries of the heretical editors. It was the case in the 17th as in the 16th century that the editors who had interested themselves in producing the editions of these works of the Fathers were in large part men whose orthodoxy had come into question. There were, in fact, but very few editions of the Fathers of the Church the editorial work in which had been in the hands of orthodox or conservative believers. Among the editions so prohibited, were the works of Cyprian with the notes of the Frenchman Maran, and the Letters of Chrysostom in the edition printed in Basel. Prohibited also was a work by Erigena in a German edition and the history of the Council of Constance by von Hardt. In the list of classics are to be found Italian editions of the works of Caesar, Ovid, Anacreon, and Lucretius.
