A REVIEW OF EARLY ASTRONOMY
by Julian A. Smith
EARLY ASTRONOMY (New York: Springer-Verlag, 1994, 258 pages plus index) is a remarkably sure-footed summary of the history of mathematical astronomy in the pre-telescopic era. Ten chapters explain the astronomical work of prehistoric Man, the Megalithic builders, Babylonia, Egypt, China, Ancient Greece, India, Islam, the Mayans, and the European Renaissance. Written by University of British Columbia mathematician and historian of astronomy Hugh Thurston, EARLY ASTRONOMY is especially strong in its technical and mathematical detail. No mere summary of astronomical concepts through the ages, Thurston's book includes almost two hundred geometrical diagrams that explain in detail the mathematical theories behind them, including Megalithic alignments, Babylon's "system A" and "system B" astronomy, Eudoxus' homocentric spheres, Hipparchus' theory of deferents and epicycles, and so on.
A similar attention to detail is given in Thurston's consideration of astronomical devices. Though this is emphatically not a history of instrumentation, EARLY ASTRONOMY differs from many general histories of astronomy by describing the mathematical workings of meridian arcs, quadrants, and armillaries in some depth.
It is curious that while Thurston does devote chapters to both Arabic Astronomy and the Renaissance, he avoids any description of astronomy in Medieval Europe. This is a regrettable omission, given the historical predecessors of Copernicus, and the ample scholarship in this area (interested readers might look at the works of Pierre Duhem, Olaf Pedersen, Edward Grant, Lynn Thorndike, David Lindberg, and many more, in this connection).
There are other lacunae in the text. In Thurston's discussion of the origin of star nomenclature (pages 1-4), Richard Allen's (1838-1908) helpful classic STAR NAMES, THEIR LORE AND MEANING (New York: Dover, 1963) is left out. Similarly, Thurston alludes to the Ishango bones (page 53), possibly the earliest astronomical instrument of all, but does not describe them further. He follows Otto Neugebauer's thorough HISTORY OF ANCIENT MATHEMATICAL ASTRONOMY (New York: Springer-Verlag, 1975) in several respects, including his abrupt dismissal of Egyptian astronomy in two pages (pages 82-83). Yet given recent archaeological and historical research on Egyptian instrumen- tation and iconography, surely more could have been done here.
Regarding Arabic astronomy, Thurston says that "we are in sore need of a general study of Arabic astronomy by a specialist" (page 251). Yet there are several Variorum editions that cover this area in some depth, including David A. King's new compilations, ASTRONOMY IN THE SERVICE OF ISLAM (Aldershot, Hampshire: Variorum, 1993), ISLAMIC ASTRONOMICAL INSTRUMENTS (London: Variorum, 1987), and ISLAMIC MATHEMATICAL ASTRONOMY (London: Variorum, 1986; rev. ed. 1993). Only six pages are given to Arabic astronomy from al-Khwarizmi (ca.800- ca.847) to Ulugh Beg (1394-1449). A summary of King's research would have allowed this chapter to be considerably extended.
Even so, Thurston has managed to pack a great deal of information into the 258 pages of this text. What has been lost in scope (Egypt, Medieval Europe, Islam) has been partially made up by the detailed mathematical analysis of Greek and Renaissance Astronomy. Thurston is particularly thorough in his study of Ptolemy's ALMAGEST. He concurs with R. R. Newton's assertions in THE CRIME OF CLAUDIUS PTOLEMY (Baltimore: Johns Hopkins, 1977) that Ptolemy invented or modified others' observations to get his results; and he explains how Ptolemy borrowed both theory and data from Hipparchus. There are six appendices, which amplify the mathematical techniques employed by the two Greek astronomers. EARLY ASTRONOMY contains a helpful if incomplete bibliography, but there is a thorough index.
