General map of Africa characterized by Delisle's scientific approach. It extends from parts of Europe and Asia in the north till Cape Agulhas the southern tip of the continent; and it stretched from a part of Brazil in the west till the Indian Ocean in the east. Delisle shows impressive detail all over the continent indicating the names of native kingdoms, gold, silver, emerald, and salt mines, wells in the desert, rivers, lakes, gulfs, capes, rivers, mountains... In the first edition of this map was a landmark in the mapping of Africa, Delisle was the first to give the correct longitude of the Mediterranean (42 degrees), thus rectifying the northern coastline of the contient. He was also the first to give the correct source of the Nile from lake Tzana in Abyssinia, instead of Lakes Zaire and Zaflan inherited from Ptolemy. In the updated editions after 1722, Delisle was the first to separate the Senegal and Niger rivers, he also depicted a large lake Moravi inland from Zanzibar with the mountains of Lapata, the spine of the world. In the top left corner, it includes an elegant title cartouche.
This map was first published in 1700 by Guillaume Delisle, it was revised and updated in 1722. The present example is a later reprint of the updated by Philipe Buache published after his death.

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.
