IMBERT, J. Leopold
Carte des Possessions Angloises dans l'Amerique Septentrionale Pour Servir d'Intelligence a la Guerre presente
Paris: chez Mondhare, 1777. Copper engraved map, period hand-colouring in outline. Inset of Florida and the West Indies. Sheet size: 22 x 30 inches.
First edition of Imbert's rare map of the theatre of war in North America and the basis for one of the most important French mappings of the new United States.
This map was issued in Paris to meet the demand for maps of America at the outbreak of the Revolution. The map depicts the English colonies extending to the Alleghenies, showing a vast Louisiana as far west as the far side of the Mississippi. "Covers the area east of the Mississippi River from James Bay to the Gulf of Mexico. Shows states, towns and cities, Indian villages and tribal territory, routes of navigation along the southern coast and relief" (Sellers and Van Ee). A large inset shows Florida south of St. Augustine, as well as the Bahamas, Cuba, Hispaniola and Jamaica. A hachured border line shows the British colonies extending only to the Appalachians. Cartographically, Imbert's map follows the mappings by other French cartographers of the 18th century, including De L'Isle, d'Anville and Brion de la Tour. Imbert's map would be reissued by Jean-Baptiste Eliot in 1783, that edition being one of the first maps issued following the provisional Treaty of Peace. Eliot's map, which is printed from the same plate as the present map by Imbert, shows the new boundaries of the United States according to that treaty depicted via x's. The Eliot map is otherwise the same as the present map by Imbert, with the notable exception of wording changes to the cartouche; i.e. changing "des Possessions Angloises" to "des Etas Unis" and Eliot removing Imbert's name and substituting his own.
