Antique chart of Brazilian coast and mouth of the Amazon River

Carte des Cotes Septentrionales du Bresil depuis Maranham jusqu'a l'embouchere de la Riviere des Amazones

DESCRIPTION: Antique French sea chart from 1842 covers the mouth of the Amazon River in Brazil. This fine large copper-plate engraved nautical chart begins north of the Amazon River near Isla Maraca and trends south then east to include Rio Araguari ( Araouari ) , Rio Amazonas, Ilha de Marajo, Para River, and the Ile de Maranham. Includes the towns of Belem (Para) , Sao Luis (San Luiz) , Macapa, Chaves, and numerous smaller villages. Includes an inset chart/plan of the Para River with Belem.

Dozens of smaller rivers and tributaries of the Amazon are identified by name along with hundreds of depth soundings in meters. After a lapse of 25 years France had recently re-adopted the metric system in 1837. At bottom left the authors provided a useful depth conversion table from meters to feet (pieds), and to the old measure of depth- brasses (about five feet).

With the circular logo of the Depot Generale de la Marine. All text in French. No. 408.The Depot de la Marine was established in 1720 under the French Ministry of the Navy to collect, preserve, and publish nautical charts, sailing directions, and maritime intelligence for the French naval service. Its purpose was both archival and practical: to centralize geographic knowledge gathered from voyages, surveys, and colonial administration, and to convert that information into standardized charts for navigation. Over the eighteenth century the Depot became the principal hydrographic authority of France, issuing engraved sea charts that incorporated data from naval expeditions, colonial outposts, and scientific voyages.

Following the French Revolution, the institution was reorganized and its chart production expanded, particularly during the late eighteenth and early nineteenth centuries as global maritime competition intensified. The Depot de la Marine supervised official surveys, revised earlier charts, and maintained copperplates for continued reissue as coastal knowledge improved. In 1886 it was formally reorganized as the Service hydrographique de la Marine, the predecessor of today’s French hydrographic office. Charts bearing the Depot imprint remain important records of French naval activity, colonial expansion, and the technical development of European hydrography.
