During the Middle Ages and early modern times tables were a most successful and economical way to present mathematical procedures and astronomical models and to facilitate computations. Before the sixteenth century astronomical models introduced by Ptolemy in Antiquity were rarely challenged, and innovation consisted in elaborating new methods for calculating planetary positions and other celestial phenomena. Essays on Medieval Computational Astronomy includes twelve articles that focus on astronomical tables, offering many examples where the meaning and purpose of such tables has been determined by careful analysis. In evaluating the work of medieval scholars we are mindful of the importance of applying criteria consistent with their own time, which may be different from those appropriate for other periods.

Seeing with Different Eyes: Essays in Astrology and Divination represents the cutting-edge of contemporary thought and research on divination. The thirteen authors come from a variety of academic disciplines, ranging from anthropology and classics to English literature and religious studies, and all address the question of divination, astrology and oracles in a spirit of critical but sympathetic inquiry. The emphasis is on a participatory and reflexive approach which is firmly post-positivi...

Christoph Rothmann wrote a treatise on the comet of 1585 shortly after it disappeared. Though it was not printed until 1619, Rothman sent a copy of his treatise in 1586 to Tycho Brahe, decisively influencing the latter's rejection of solid celestial spheres two years later. In his treatise, Rothmann joined the elimination of the solid celestial spheres to his concept of air as the substance filling the cosmos. He based his argument on the absence of refraction and the celestial location of the comet. The treatise also contained clear statements reflecting Rothmann’s adoption of Copernicanism. This first critical edition of the treatise is accompanied by an English translation and a thorough commentary. Some appendices with archival documents illustrate the genesis of Rothmann’s treatise.

A Survey of European Astronomical Tables in the Late Middle Ages is a first attempt to classify and illustrate the numerous astronomical tables compiled from about the 10th century to the early 16th century in the Latin West. The compilation of astronomical tables was a major and dynamic intellectual enterprise. These tables respond to a wide variety of astronomical problems and computational needs, and contain a large number of ingenious solutions proposed by astronomers over the centuries. In the absence of algebraic notation and mathematical graphing techniques, a table was often the best way to transmit precise information to the reader. Indeed, an astronomical table is not a just a list of data, but a structured way to present numerical information of astronomical interest. '...the whole book which is an excellent guide for all those who are interested in the history of medieval European astronomy and, especially, in medieval astronomical tables.' Julio Samsó, University of Barcelona
