This finely detailed late 18th-century French copperplate map by Rigobert Bonne depicts Northern India and the heartland of the Mughal Empire, stretching from the western coast of Concan and Gujarat across to Bengal, Assam, and northern regions bordering Tibet. An inset map in the corner highlights the complex hydrography of the Mouths of the Ganges (Bouches du Gange), illustrating key river routes, anchorages, and coastal settlements essential for maritime trade. Rigobert Bonne, serving as the Hydrographer to the Royal Navy of France, was renowned for his geographical precision and clear cartographic style. The map delineates major regional kingdoms, provincial borders, mountain ranges, and prominent urban centers such as Delhi, Agra, Calcutta, and Surat, offering a comprehensive view of the subcontinent during a pivotal period of European mercantile expansion.
