This very unusual double hemisphere map was engraved by Jean Somer Pruthensus. It displays simple outlines of the continents, shows California as an island, and illustrates meridians and climatic zones. There are no place names, and the interior of the continents are completely blank. The map was included in Sanson's atlases from 1659 onwards. This is a later edition with the addition of a wind rose in between the hemispheres and several diagrams along the bottom border.
