A factor to be taken into account in considering the selections of books ordered to be condemned, was the patriotism of the Italian clergy, in whose hands rested the control of the operations of the Congregation. They were as unwilling to characterise as pernicious noteworthy and representative books by Italian writers, as they were to place any one but an Italian on the throne of St. Peter. This partisan zeal for the literary glory of Italy must frequently have seriously interfered with the aim of securing a consistent and effective Index and have brought upon a conscientious pope not a little embarrassment. An example of the difficulty experienced by Rome in enforcing a consistent censorship in the face of Italian patriotism, on the part of ecclesiastics, no less than of laymen, is afforded by Dante and Petrarch. Of the former, was prohibited the _De Monarchia_, but the _Divine Comedy_, with all its bitter strictures of things ecclesiastical, escaped condemnation and even expurgation. The _Canzoniere_ of Petrarch were also left untouched by Rome, although the Inquisition of Spain had characterised them most severely in the Indexes of 1612 and 1667. It was not until 1667 that the _Satires_ of Ariosto were placed upon the Index, while the _Comedies_ of the same poet were never condemned although in these the poet had assailed fiercely the trade in indulgences, and had painted a vivid picture of the traffic carried on by the capital of the Christian world with the blood of the apostles and martyrs. The example of independence set by Venice in its series of contests with the Church for the freedom of the press had a natural influence in other cities of Italy where conditions were favourable for publishing activity. In Florence, Pisa, Ferrara, Milan, and other cities in which scholarship had flourished during the manuscript period, the productions of the printing-press became, during the 15th and 16th centuries, of increasing importance. This work was frequently interfered with and sometimes seriously hampered by the censorship regulations of Rome and by the operations of the local inquisitors, but it was never entirely blocked even in any one city. The feeling of State and municipal independence and the individuality of the people were too strong to be crushed out by Roman edicts or by the threats of the Inquisition. In Italy as in Germany, the fact that there was not one government in the peninsula, but a number of independent States, helped to secure for the work of the printers some degree of opportunity, notwithstanding the censorship edicts of the Church and the repressive measures of the State. The presses of the day were small and in case of trouble in one city, they could easily be moved to another.
