"There is much here for Professor Graney's intended student audience as well as for other interested readers. His efforts will make the understanding of this Copernican debate richer for all." —Renaissance Quarterly"With this translation, Graney makes available to a wider range of readers Locher's ideas in a manner unmediated by the thoughts or the agenda of Galileo. It allows them to explore and assess on their own merits the arguments advanced by critics of Copernicanism in the early seventeenth century. This in turn makes it possible to understand contemporary cosmological debates in new ways." — European History Quarterly"In this accessible and engaging translation, Graney makes a strong case for the value of studying the anti-Copernicans. . . The recovery of Locher's treatise demonstrates that 'Science's history matters' because it shows that true and honest debates within the scientific community have been part of the practice of modern science since its inception." —Seventeenth-Century News"Graney is doing sterling work in adjusting the very distorted view of the astronomical system in the first half of the seventeenth century and anybody, who is seriously interested in learning the true facts of the discussion, should definitely read his latest contribution." —The Renaissance Mathematicus
