An 18th century wall map of the world

A large and impressive double-hemisphere world map, with a dedication cartouche in the upper cusp and allegorical figures of the four continents in the lower one. The rest of the borders are filled will astronomical diagrams. On the map the voyages of the important circumnavigators are marked, and an attempt has been made to show the discoveries of Cook's Third Voyage to the Bering Strait, although not accurately.
