"Before Copernicus is of potentially great importance to the larger field of the history of fifteenth- and sixteenth-century science and the interaction between the Islamic and Western intellectual worlds. Although many books have been written about individual parts of this story no one has tried to put this all together before." Lesley Cormack, University of Alberta "These scholars are the best in their fields. Their essays are well-researched, up-to-date historiographically, and interestingly written. This volume could prove controversial, but by exposing the contested issues more clearly, it will greatly enhance the scholarly conversation." Richard Kremer, Dartmouth College "The authors are all outstanding experts in their fields and have done an excellent job, even if their contributions to the overall result maybe unequal. The sheer number of facts offered here is astonishing. The extraordinary level of knowledge and the concise presentations are a pleasure, though simultaneously an intellectual challenge, and will enrich the reader's mind. For all those interested in high-level history of science I can strongly recommend this book." Isis Journal <p>"In addition to its value for scholars interested in transmission, <i>Before Copernicus</i> is essential reading for historians of Renaissance science or the history of astronomy. It is also a fascinating example of how to combine technical and cultural history of science (what we used to call internalist and externalist approaches) in a single project. I expect this will be on methodology reading lists for years to come." Journal of World History</p> "This stimulating collection of essays presents a rich picture of the intellectual milieu out of which Copernicus had developed his earliest version of the heliocentric system and should be of great interest to a wide range of historians beyond specialists in Renaissance astronomy. Taken together, the essays underline the continuing need for comparative studies of the intellectual and cultural contexts of science around the Mediterranean. They also suggest that future research, particularly that focuses on lesser-known individuals or unedited sources, has the potential to significantly revise existing narratives about the development of early modern science."
