Astronomy in the Iberian Peninsula : Abraham Zacut and the Transition from Manuscript to Print Transactions, American Philosophical Society (vol. 90. Part 2) (Transactions of the American Philosophical Society)

Chabs and Goldstein distinguish Zacut's (1452-1515) Almanach Perpetuum (1496) from his ha-Hibbur ha-gadol , or The Great Composition (1478), which was long considered merely a translation of it. Their main purpose is to analyze the astronomical tables that accompanied the almanac. They also try to assess Zacut's influence on subsequent astronomers. Annotation c.
