This map was published in the work entitled ‘Description de la Louisiane’. Although his later works are much criticised and discounted for their inaccuracies the reputation of his first narrative is largely intact. It contains the first account of Robert Cavalier, Sieur La Salle’s journey through Niagara Falls, the Illinois country, and the Upper Mississippi River. It is also the first to use the name Louisiana although it was La Salle who thought of it. It a classic of Mississippi River cartographic history and illustrates the territory through which La Salle travelled and the Mississippi as far south as Jolliet and Marquette travelled which was Arkansas River. From here Hennepin draws a dotted line indicating Jolliet and Marquette’s belief that the River flows directly southwards into the Gulf of Mexico. This example has been cut in the book and is here backed on tissue to support it with no loss. With one tear near a double fold, also restored, no loss. Overall a decent example of an extremely rare map not seen on the market in many years. Church (1907) no. 774, Wheat (1957) pp. 49-50 & no. 62.
