This rare pair of maps depict the eastern coastline of South America from the Orinoco River in Venezuela to the Rio de la Plata between Uruguay and Argentina. The focus of the maps is on the extensive rivers systems of the Amazon, Parana, and the numerous smaller rivers all along the coast. A few early forts are also noted. These maps were published in Atlas Maritimus & Commercialis, an atlas with several joint publishers, among them James and John Knapton, William and John Innys, and John Senex. Senex is often credited with preparing the various charts therein. Most likely engraved by Samuel Parker, who is credited on other charts in the atlas. According to Shirley, the atlas is often catalogued under Astronomer-Royal Edmund Halley, who contributes an introductory note on the projection used throughout the atlas.
