About the Cover
The image on the cover is from an engraving at the Granger Collection in New York. It depicts Claudius Ptolemy, an astronomer from the second century A. D. Ptolemy codified the Greek geocentric view of the universe, and rationalized the apparent retrograde motion of the planets using epicycles. The Ptolemaic system remained the accepted wisdom until the Polish scholar Copernicus proposed a heliocentric view in 1543.
