ABSTRACT This paper explores the rules for the expurgation of texts of astrology in the Iberian Indices of forbidden books. It addresses the prohibitions put forward in Rule IX of the Index of Trent and the bull Coeli et terrae of Sixtus V, and studies its impact on the rules and their interpretation in the Spanish and Portuguese Indices, in particular, those published in the first decades of the seventeenth century: the Spanish Index librorum prohibitorum et expurgatorum of 1612 and the Portuguese Index auctorum damnatae memoriae of 1624. It shows how these indices offer a more meticulous examination of the prohibitions providing not only more detail regarding the different practices of astrology, but also explicitly accept the doctrine of inclinations of Thomas Aquinas as a central rule to deal with astrological judgments on human behaviour. It also highlights some specific details of the practice of censorship of astrological books by examining case studies of censored Portuguese and Spanish astrological publications. These provide new dimensions and highlight significant differences between the theoretical rules, practical guidelines, and actual restriction of astrological content.

有界的天堂：用伊比利亚指数定义占星术实践的极限

摘要 本文探讨了在伊比利亚禁书索引中删除占星术文本的规则。它解决了特伦特指数第 IX 条和 Sixtus V 的公牛 Coeli et terrae 中提出的禁令，并研究了其对西班牙和葡萄牙指数中的规则及其解释的影响，特别是那些在最初几十年发布的指数17 世纪：1612 年的西班牙索引 librorum preventorum et expurgatorum 和 1624 年的葡萄牙索引 auctrumdamatae memoriae。还明确接受托马斯·阿奎那的倾向学说作为处理对人类行为的占星学判断的核心规则。它还通过检查被审查的葡萄牙和西班牙占星学出版物的案例研究，突出了占星学书籍审查实践的一些具体细节。这些提供了新的维度，并突出了理论规则、实践指南和占星术内容的实际限制之间的显着差异。
