Magini’s edition of Ptolemy’s Geography

Ptolemy's Geography translated into Italian and corrected by Magini (1555-1617), Professor for Astronomy, Astrology and Mathematics at the University of Bologna. Both the Ptolemaic and modern maps were mostly reduced from Mercator's atlas by Girolamo Porro, predating the official Hondius pocket atlas by nearly a decade, although a few maps (for example the second world, America, Northern Europe and North Pacific) are derived from Ortelius.
