Scarce map of the Western Hemisphere, from the first edition of Jean Boisseau's Tresor des Cartes, the first true French world atlas.
Boisseau's atlas was created for the eight-year-old future King Louis XIV. Based largely on Jansson's map of America from Atlas Minor, 1628, the most dominant feature of the map is the curious depiction of the west coast of North America, which is completely bisected by an unnamed straight (Northwest Passage), possibly derived from reports of Juan de Fuca's disputed voyage.
The bulging northwest coast of North America continues another 65 degrees and is separated from Asia by a narrow Estroit d'Anian. These features were derived from the Van den Keere and Plancius globe of 1614. Previous maps had depicted the supposed Northwest Passage through the Strait of Anian. Other interesting features include the St. Lawrence River flowing from a small lake in the West and no Great Lakes.
The map includes a number of mythical islands in the Atlantic, including Brasil, Frislande and aI. das Maidas.
