Le Rouge’s stunning and rare 4 sheet sea chart of the Atlantic Ocean first appeared in his Pilote Americain Septentrionale published in 1778. The Pilote Americain was published for the French Navy during the American Revolution. It was one of the primary source material to help it and french merchants alike in their efforts to break the British blockade to the American Colonies. Although French involvement in the American conflict was initially limited to a supporting role, France’s decision to recognize the new political entity of the United States on February 6, 1778, led to the declaration of war by Great Britain against France on March 17, 1778.
The 4 sheet sea chart is an adaption of a chart who's provenance originally comes the second part of the North American Pilot first published in 1776 by Sayer and Bennett and then reissued in 1777 which included a double page chart of the Atlantic Ocean.
As a map maker for the French army and the Marine Royale, Le Rouge’s maps were highly prized especially during naval or military conflicts abroad. In 1747, Le Rouge would partner with John Rocque, an english immigrant of french huguenot origins, to translate and adapt English maps, such as those from the firm of Thomas Jefferys, for the French market.
Le Rouge’s importance to cartography can also be underlined by his prolific output during the American Revolution. A recently sold broadside catalogue issued circa 1778-80 listing the maps published by his firm, indicates that a third of the maps put up for sale relate to North America and the Caribbean.
The present rare map Ocean Atlantique et Mers Adjacentes en quatre feuilles Contenant les Cotes de l’Europe, de l’Afrique et de l’Amérique is rarely sold on the market due to the fact that it appeared in an atlas who’s original purpose was designed for use by the French Navy at sea.
