This monograph is devoted to an analysis of the major sets of tables in Latin used by astronomers in the late Middle Ages and the early modern period, revealing the connections between them, and exploring the transmission of astronomical knowledge. We present in chronological order, as far as possible, these sets of tables, arranged in four parts. Part I examines the background for the work of Andalusian table-makers, and includes a brief survey of the tables compiled by Ptolemy and those in the zijes of al-Khw?rizm? and al-Batt?n?, for these sets had a major influence on medieval western astronomers. Part II deals mainly with the two principal astronomical traditions developed in al-Andalus and subsequently in the rest of the Iberian Peninsula, with special focus on the Toledan Tables. In Part III the emphasis is on the Castilian Alfonsine Tables developed in Toledo in the second half of the thirteenth century and later recast by several astronomers, mainly in Paris, to become what is called the Parisian Alfonsine Tables. Part IV presents later collections of astronomical tables, mostly in the Alfonsine framework, with an emphasis on their user friendliness. This volume may serve as a guide for researchers in identifying sets of tables and it may also serve as a tool to recognize isolated astronomical tables in miscellaneous manuscripts or even those mixed in with other tables. For that purpose, many sets of tables have been examined in more than 350 manuscripts and printed editions. With this volume, the CSIC consolidates a long tradition of publications in the history of medieval astronomy.
