A striking wall map of the world at the end of the 18th century

A large and rare chart of the world, decorated with a title cartouche featuring a naval officer examining a chart and a midshipman using a sextant, and four compass roses. In the bottom corners are two text panels giving instructions on how to measure distances correctly on the map. The map was originally drawn up by Carington Bowles but does not seem to have been published before his death in 1793. This example, published by his son Henry Carington Bowles and Samuel Carver, has been updated with Vancouver's discoveries in Canada and the Bass Strait in Australia.
