“In Ordering the heavens: Roman astronomy and cosmology in the Carolingian Renaissance, Bruce Eastwood has produced an important book, valuable not only for what it tells us about Carolingian astronomy and cosmology, but also because it forces at least a partial reassessment of the importance of Roman writings in these areas. […]Eastwood’s book is well illustrated, with images carefully chosen and reproduced. His long-standing interest in diagrams is particularly brought to bear in the final chapter of the book, in which he confronts many important issues regarding their production, function and use.”
Liba Taub, BSHM Bulletin Volume 25 (2010)

"La familiarita con i concetti di eccentrico ed epiciclo sara fornita al mondo carolingio, secondo la ricerca di Eastwood, dalla pregnante attenzione concessa in quel tempo allo studio di testi scientifici di eta romana che, pur con le precisazioni cui mi e sembrato opportuno far cenno, vengono a constituire la privilegiata fonte delle conoscenze astronomiche dell'Europa di Carlo Magno."

"The rich material presented in the book, which includes numerous reproductions of manuscript pages, its nuanced analysis, and its conceptual contributions make it valuable not only for those who are interested in medieval science or manuscript studies but for a much broader audience. The new perspectives that this book opens and the new questions that it generates are bound to have influence beyond its immediate subject."
