<p>“Raz Chen-Morris masterfully argues that Kepler’s optics is a response to widely shared anxieties about vision in Renaissance culture. This book is the first to show why the <i>Paralipomena </i>was important for Kepler, and how it was a book of cultural significance instead of a response to a narrowly defined technical issue.”</p><p>—Sven Dupré, Institute for Art History, Freie Universität Berlin</p>

<p>“Neither the disembodied mind that charted the path toward modern mathematical physics, nor the Neoplatonic magus who dreamed of hearing the music of God's celestial spheres, Johannes Kepler, in Raz Chen-Morris's erudite and multiperspectival reading, is a fully embodied early modern intellectual striving to resolve deep questions at the heart of early modern thought. <i>Measuring Shadows</i> is not just a new history of Kepler’s optics; it is a book about the early modern European life and preoccupations that led Kepler to his world-changing scientific achievements. As such, it is a brilliantly insightful contribution to the cultural history of early modern science.”</p><p>—J. B. Shank, University of Minnesota</p>

<p>“Students of the history of astronomy, science historians, and graduate-level students who are involved in the study of optics and how Kepler derived his planetary laws of motion will benefit from this work. It is also a valuable acquisition for university and college libraries and major public libraries.”</p><p>—C. G. Wood <i>Choice</i></p>
