This map of French Guyana and the island of Cayenne is by Jacques Bellin (1703-72), a prolific cartographer attached to the French Marine Office. It reflects the careful mapping of bays, seas, and harbors that characterized 18th-century French naval cartography. In addition to the detailed information about the coast, Bellin’s map includes notes about the interior of this part of South America, much of which was still largely uncharted by the Europeans.
