The map of South America extends from the south of Peru and Brazil to Tierra del Fuego, with the Strait of Magellan and Cape Horn to the south ("This coast is not well known"), and the mouth of the Rio de la Plata to the east. It shows the routes taken by different navigators (Magellan, Sarmiento, Halley, Vespucci, etc.), and mentions in the Atlantic Ocean that "In this icy sea there are many animals that are half birds and half fish: they have a neck like a swan that they advance out of the water only to take air the rest is always under water".

Guillaume Delisle (de l'Isle) (1675-1726), is one of the greatest figures of French cartography. The eldest son and pupil of the historian and geographer Claude Delisle, he entered the Academy of Sciences in 1702 to study with the astronomer Jean-Dominique Cassini. He taught geography to the young Louis XV and was the first to receive the title of Premier Géographe du Roi in 1718. Delisle is considered to be at the origin of modern cartography. One of Delisle's main contributions was to make a transition from the decorative maps of the Dutch school to a more scientific approach. He removed the ornamental elements and based his cartography on all available information. Throughout his life he constantly updated his collection of over 100 maps to reflect new discoveries. Thus, his maps give a precise overview of the state of geographic knowledge at the time. Delisle’s was the first to correct the longitudes of America, to discard the well-established fallacy of California as an island, to delineate the Mississippi Valley correctly and to introduce many new name places.
