The collection of papers assembled here on a variety of topics in ancient and medieval astronomy was originally suggested by Noel Swerdlow of the University of Chicago. He was also instrumental in making a selection* which would, in general, be on the same level as my book The Exact Sciences in Antiquity. It may also provide a general background for my more technical History of Ancient Mathematical Astronomy and for my edition of Astronomi cal Cuneiform Texts. Several of these republished articles were written because I wanted to put to rest well-entrenched historical myths which could not withstand close scrutiny of the sources. Examples are the supposed astronomical origin of the Egyptian calendar (see [9]), the discovery of precession by the Babylonians [16], and the "simplification" of the Ptolemaic system in Copernicus' De Revolutionibus [40]. In all of my work I have striven to present as accurately as I could what the original sources reveal (which is often very different from the received view). Thus, in [32] discussion of the technical terminology illuminates the meaning of an ancient passage which has been frequently misused to support modern theories about ancient heliocentrism; in [33] an almost isolated instance reveals how Greek world-maps really looked; and in [43] the Alexandrian Easter computus, held in awe by many historians, is shown from Ethiopic sources to be based on very simple procedures.

A gathering of essays from various scientific journals by the noted British astronomer, Richard A. Proctor (1837-88). Proctor was the author of more than 40 books on the subject and is credited with popularizing astronomy in the 19th century. He was the first to suggest that lunar craters were the result of meteor impacts and not volcanic activity and won recogition for his 1867 map of the surface of Mars showing continents, seas, bays and straits. This book contains essays on subjects including: Sir John Herschel; the planet Mars; Saturn's rings; meteors and shooting stars; the zodiacal light; the solar corona; the sun's journey through space; distribution of the nebulae; a new theory of the Milky Way; the diurnal rotation of Mars; the proper motion of the Sun; the transit of Venus in 1874 and many other subjects. The illustrations include a handsome frontis lithograph of Saturn and its rings and there is also a folding plan of the orbits of Earth and Mars and 5 folding charts showing various stages of the transit of Venus in 1874. There are 3 full-page polar and equatorial maps on black paper showing distribution of Nebulae.

Download Essays on Medieval Computational Astronomy Book in PDF, ePub and Kindle
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.
