”Ptolemy`s Geography” is the only book on cartography to have survived from the classical period and one of the most influential scientific works of all time. Written in the second century AD, for more than fifteen centuries, it was the most detailed topography of Europe and Asia available and the best reference on how to gather data and draw maps. Ptolemy championed the use of astronomical observation and applied mathematics in determining geographical locations. But more importantly, he introduced the practice of writing down coordinates of latitude and longitude for every feature drawn on a world map, so that someone else possessing only the text of the ”Geography” could reproduce Ptolemy`s map at any time, in whole or in part, at any scale. Here, Berggren and Jones render an exemplary translation of the ”Geography” and provide a thorough introduction, which treats the historical and technical background of Ptolemy`s work, the contents of the ”Geography”, and the later history of the work.Also included here are unique color reproductions of maps from manuscripts and early printed editions of the text, representative of the beautiful and practical cartographic artistry that flowed from Ptolemy`s work. Historians of science, classicists, and anyone who enjoys beautiful maps or map making will find this work an indispensable addition to their library.
