ABSTRACT During the sixteenth and seventeenth centuries, the Inquisition was the institution most invested in the censorship of printed books in the Portuguese empire. Besides publishing the Indices of Forbidden Books, the Holy Office was also responsible for overseeing their implementation and ensuring their efficacy in preventing the importation, reading, and circulation of banned books. Overall, the sixteenth-century Indices condemned 785 authors and 1081 titles, including 52 authors and 85 titles of medicine, natural history, natural philosophy, astronomy, chronology, cosmography, astrology, and divinatory arts. By looking at the largest collection of early modern scientific books in Portugal, I will argue that a closer inspection of marginalia and ownership, and the establishment of a typology of expurgations is essential for the comprehension of the actual practices and the mechanisms of censorship. By examining the material evidence of censorship, in order to reconstruct expurgation practices, this paper reveals the processes and effectiveness of ecclesiastical control in the Portuguese Inquisition and highlights the differences between what inquisitors wrote in the Indices and what others put into practice.

将指数付诸实践：审查现代早期葡萄牙的科学

摘要 在 16 和 17 世纪，宗教裁判所是葡萄牙帝国在印刷书籍审查方面投入最多的机构。除了出版禁书索引外，圣公署还负责监督其实施，确保其在防止禁书进口、阅读和流通方面的有效性。总体而言，16 世纪指数谴责了 785 位作者和 1081 个标题，其中包括医学、自然历史、自然哲学、天文学、年代学、宇宙学、占星术和占卜术的 52 位作者和 85 个标题。通过查看葡萄牙最大的早期现代科学书籍收藏，我认为仔细检查边缘和所有权，建立清除类型学对于理解实际做法和审查机制至关重要。本文通过审查审查的实物证据，以重建清除实践，揭示了葡萄牙宗教裁判所中教会控制的过程和有效性，并突出了宗教裁判官在索引中所写的内容与其他人实施的内容之间的差异。
