Mercator after Ptolemy
Universalis Tabula Iuxta Ptolemaeum
Gerard Mercator's version of Ptolemy's map of the world.
Claudius Ptolemy was librarian of the famous library of Alexandria and he had developed these maps for his "Geographia" around 150 AD and they reflect the best Roman geographical knowledge.
The work was rediscovered in the 15th century and the maps were reissued in the sixteenth and 17th century. The versions by the great cartographer Gerard Mercator are generally considered the most decorative and most skillful rendering of Ptolemy maps.
