A pair of maps of the Western and Eastern hemispheres

A decorative pair of maps of the world in two separate hemispheres, both with allegorical figures representing the Four Continents in the corners. In the Western Hemisphere California is an island; a huge Great Lake is open-ended in the west; and New Zealand is mapped according to Abel Tasman. In the Eastern Hemisphere, the Caspian Sea is wider than it is tall; and the east coast of Australia is unmapped, pre-dating Cook's visit by three-quarters of a century. Published in the 'Historia moderna Europae', an account of Europe's recent political history.
