The Astronomical Tables of Giovanni Bianchini


The Alfonsine Tables became the main computing tool for astronomers for about 250 years, from their compilation in Toledo ca. 1272 to the edition in 1551 of new tables based on Copernicus’s astronomical models. It consisted of a set of astronomical tables which, over time, was presented in many different formats. Giovanni Bianchini (d. after 1469), an astronomer active in Ferrara, Italy, was among the few scholars of that extended period to compile a coherent and insightful set based on the Alfonsine Tables. His tables, described and analyzed here for the first time, played a remarkable role in the transmission of the Alfonsine Tables and in their transition from manuscript to print.

"Les Tables sous examen sont probablement l'ensemble le plus volumineux produit en Europe dans le genre avant les temps modernes. Dans la mesure où le travail de l'astronome de Ferrare s'inscrit dans la continuité des Tables alphonsines, cet accroissement fait mieux comprendre et mieux apprécié le travail accomplit par les astronomes du roi Alphonse X de Castille dans la deuxième partie du XIIIe siècle."

"L'analyse technique est à tout point de vue excellent et ne prête pas à redire."

Max Lejbowicz, Aestimatio 6 (2009) 155-161

"The book [...] is an important step, shining a more focused light on Bianchini's inventive Tabulae astronomiae, providing a succinct technical guide to its contents, and describing clearly its innovations."
"The history of astronomy can only benefit from an increased attention to numerical tables, and this book is an excellent contribution. It is highly recommended for readers with the appropriate background."
