A mid-18th century double-hemisphere map of the world

A decorative double hemisphere world map drawn by Georg Moritz Lowitz, based on the work of Professor Johann Mathias Haas. It depicts four polar spheres, each with a different projection, plus two diagrams showing the earth position with the suns solstice. North America is still blank above California and Hudson Bay is open-ended in the north-west corner. In the South Pacific there are partial coastlines of New Zealand Australia as discovered by Able Tasman. Two large, decorative cartouches contain the titles, one in Latin, the other in French.
