This paper evaluates Kepler's 1618–1621 Epitome of Copernican Astronomy in light of two contextual events: the 1616 Decree of the Index banning Copernican books (including Volume 1 of Kepler's Epitome in 1619) and the start of the Thirty Years' War in 1618. Kepler's Epitome seems to defy traditional genre expectations: it takes the form of a textbook, and yet (especially in later volumes) it is more complicated than a traditional university primer, and seems targeted toward more expert readers. I argue that Kepler deliberately reframed the Epitome and modified its focus and approach in the years between the publication of its first volume in 1618 and its later volumes in 1620 and 1621. These changes were related to Kepler's attempt to circumvent the ban on the first volume and help the book reach readers in Italy. To Kepler, a lifelong advocate for the Copernican cause, it was imperative that his book reach as many readers as possible. The spread of his work would both help educate potential future Copernicans and aid in overturning the ban on Copernican publication itself. Further, Kepler believed that princely readers might use the book's arguments as a model for peace in a time of war.

开普勒的哥白尼天文学缩影

本文根据两个上下文事件来评估开普勒的1618–1621年哥白尼天文学的缩影：1616年禁止哥白尼著作索引法令（包括1619年开普勒的《缩影》第1卷）和1618年三十年战争的开始。缩影似乎违背了传统体裁的期望：它采用教科书的形式，但是（特别是在后来的书中）它比传统的大学入门书更为复杂，并且似乎针对更多的专业读者。我认为开普勒故意重塑了《缩影》并在1618年第一本书出版到1620年和1621年以后出版之间的几年中修改了其重点和方法。这些变化与开普勒试图绕开第一本书的禁令并帮助该书覆盖意大利的读者有关。 。对于开普勒一生的终身倡导者开普勒而言，当务之急是让他的书尽可能多地吸引读者。他作品的传播既有助于教育潜在的未来哥白尼主义者，也有助于推翻对哥白尼出版物本身的禁令。此外，开普勒（Kepler）相信，在战争时期，读者可以将王子的论据用作和平的典范。
