Nice example of the Chatelain version of Guillaume De L'Isle's maps of the northern part of South America.
The map shows Colombia, Venezuela, Peru, Ecuador, Brazil, Guiana and parts of Bolivia, Chile, Paraguay and Argentina.
De L'Isle was known for his fine scientific mapping style, restricting the cartographic content of his maps to what he deemed to be reliable reports and eliminating speculative information. Through a meticulous process of comparing the reports from multiple sources, he was able to reconcile diverse data to create the best maps of the period.
The detail in the Amazon River and its tributaries is quite advanced for the period, as is the treatment of the Andes mountains.
Henri Abraham Chatelain (1684-1743) was a Huguenot pastor of Parisian origins. Chatelain proved a successful businessman, creating lucrative networks in London, The Hague, and then Amsterdam. He is most well known for the Atlas Historique, published in seven volumes between 1705 and 1720. This encyclopedic work was devoted to the history and genealogy of the continents, discussing such topics as geography, cosmography, topography, heraldry, and ethnography. Published thanks to a partnership between Henri, his father, Zacharie, and his younger brother, also Zacharie, the text was contributed to by Nicolas Gueudeville, a French geographer. The maps were by Henri, largely after the work of Guillaume Delisle, and they offered the general reader a window into the emerging world of the eighteenth century.
