Cluver's Introductio in Universam Geographicam was a popular atlas, appearing in over 45 editions during a 100-year period. The first edition was published without maps in the 1620s, and the first edition to include maps was published circa 1641. The various editions were published in different cities throughout Europe, including Amsterdam, Nuremberg, and London. This engraving is from an Amsterdam edition published by Jan Wolters.
