maps that are often detached and sold to map collectors. His Introductio in universam geographiam, totally 6 parts, (published posthumously from 1624) was the first comprehensive modern geography, and became a standard geographical textbook. Clüver was also a prolific a writer on mathematical and theological subjects. He is remembered by collectors and historians of cartography for his edition of Ptolemy's Geographia (based on Mercator's edition of 1578) and for miniature atlases that were reprinted for most of the 17th century. Many of his maps were etched for him by Petrus Bertius.
