Geografia
Claudius Ptolemy
Venice, Pedrezano, 1548
G87 P8 G46 1548

Geografia is the only geographical atlas to survive from antiquity.  Preserved by the Arab world, it finally reached Venice in 1477, translated from a Greek manuscript, with new maps showing what was then known of the world.  There were many mistakes in the book, but it encouraged people, including Columbus, to believe that discovery of the unknown was possible.
