While the Spanish Inquisition has laid the greatest claim to both scholarly attention and the popular imagination, the Roman Inquisition, established in 1542 and a key instrument of papal authority, was more powerful, important, and long-lived. Founded by Paul III and originally aimed to eradicate Protestant heresy, it followed medieval antecedents but went beyond them by becoming a highly articulated centralized organ directly dependent on the pope. By the late sixteenth century the Roman Inquisition had developed its own distinctive procedures, legal process, and personnel, the congregation of cardinals and a professional staff. Its legal process grew out of the technique of inquisitio formulated by Innocent III in the early thirteenth century, it became the most precocious papal bureaucracy on the road to the first "absolutist" state. As Thomas F. Mayer demonstrates, the Inquisition underwent constant modification as it expanded. The new institution modeled its case management and other procedures on those of another medieval ancestor, the Roman supreme court, the Rota. With unparalleled attention to archival sources and detail, Mayer portrays a highly articulated corporate bureaucracy with the pope at its head. He profiles the Cardinal Inquisitors, including those who would play a major role in Galileo's trials, and details their social and geographical origins, their education, economic status, earlier careers in the Church, and networks of patronage. At the point this study ends, circa 1640, Pope Urban VIII had made the Roman Inquisition his personal instrument and dominated it to a degree none of his predecessors had approached.

In The Roman Inquisition: Centre versus Peripheries, two inquisitorial scholars, Black who has published on the institutional history of the Italian Inquisitions and Aron-Beller whose area of expertise are trials against Jews before the peripheral Modenese inquisition, jointly edit an essay collection that studies the relationship between the Sacred Congregation in Rome and its peripheral inquisitorial tribunals. The book analyses inquisitorial collaborations in Rome, correspondence between the Centre and its peripheries, as well as the actions of these sub-central tribunals. It discusses the extent to which the controlling tendencies of the Centre filtered down and affected the peripheries, and how the tribunals were in fact prevented by local political considerations from achieving the homogenizing effect desired by Rome.

In this volume, a microhistorical approach is employed to provide a transcription, translation, and case-study of the proceedings (written in Latin, Italian and Arabic) of the Roman Inquisition on Malta’s 1605 trial of the ‘Moorish’ slave Sellem Bin al-Sheikh Mansur, who was accused and found guilty of practising magic and teaching it to the local Christians. Through both a detailed commentary and individual case-studies, it assesses what these proceedings reflect about religion, society, and politics both on Malta and more widely across the Mediterranean in the early 17th century. In so doing, this inter- and multi-disciplinary project speaks to a wide range of subjects, including magic, Christian-Muslim relations, slavery, Maltese social history, Mediterranean history, and the Roman Inquisition. It will be of interest to both students and researchers who study any of these subjects, and will help demonstrate the richness and potential of the documents in the Maltese archives.

Drawing on the Roman Inquisition's own records, diplomatic correspondence, local documents, newsletters, and other sources, Thomas F. Mayer provides an intricately detailed account of the ways the Inquisition operated to serve the papacy's long-standing political aims in Naples, Venice, and Florence between 1590 and 1640.

One of the great European publishing centers, Venice produced half or more of all books printed in Italy during the sixteenth-century. Drawing on the records of the Venetian Inquisition, which survive almost complete, Paul F. Grendler considers the effectiveness of censorship imposed on the Venetian press by the Index of Prohibited Books and enforced by the Inquisition. Using Venetian governmental records, papal documents in the Vatican Archive and Library, and the books themselves, Professor Grendler traces the controversies as the patriciate debated whether to enforce the Index or to support the disobedient members of the book trade. He investigates the practical consequences of the Index to printer and reader, noble and prelate. Heretics, clergymen, smugglers, nobles, and printers recognized the importance of the press and pursued their own goals for it. The Venetian leaders carefully weighed the conflicting interests, altering their stance to accommodate constantly shifting religious, political, and economic situations. The author shows how disputes over censorship and other press matters contributed to the tension between the papacy and the Republic. He draws on Venetian governmental records, papal documents in the Vatican Library, and the books themselves. Originally published in 1977. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Drawing on ongoing research in the archive of the former Roman Inquisition, this volume presents new perspectives for research on the relations between the Catholic Church, Jews and Judaism and places them within the context of the extant scholarship on papal policy, censorship and the Marrano milieu.

Established in 1542, the Roman Inquisition operated through a network of almost fifty tribunals to combat heretical and heterodox threats within the papal territories. Whilst its theological, institutional and political aspects have been well-studied, until now no sustained work has been undertaken to understand the financial basis upon which it operated. Yet – as The Business of the Roman Inquisition in the Early Modern Era shows – the fiscal autonomy enjoyed by each tribunal was a major factor in determining how the Inquisition operated. For, as the flow of cash from Rome declined, each tribunal was forced to rely upon its own assets and resources to fund its work, resulting in a situation whereby tribunals increasingly came to resemble businesses. As each tribunal was permitted to keep a substantial proportion of the fines and confiscations it levied, questions quickly arose regarding the economic considerations that may have motivated the Inquisition’s actions. Dr Maifreda argues that the Inquisition, with the need to generate sufficient revenue to continue working, had a clear incentive to target wealthy groups within society who could afford to yield up substantial revenues. Furthermore, as secular authorities also began to rely upon a levy on these revenues, the financial considerations of decisions regarding heresy prosecutions become even greater. Based upon a wealth of hitherto neglected primary sources from the Vatican and local Italian archives, Dr Maifreda reveals the underlying financial structures that played a vital part in the operations of the Roman Inquisition. By exploring the system of incentives and pressures that guided the actions of inquisitors in their procedural processes and choice of victims, a much clearer understanding of the Roman Inquisition emerges.
