Description

Nice example of the second Dezuache's state of Guillaume De L'Isle's seminal map of Canada, the Great Lakes and Upper Midwest, the state of this highly important map to name the United States and one of the earliest appearances of the name United States (Etats-Unis) on a printed map.

The first edition of De L'Isle's map is the first printed map to locate Detroit, first issued only 2 years after the founding of the Village by Cadillac. The present edition is the eighth revision of map originally published by De L'Isle in 1703. This state is the first with "Etats-Unis" in the title.

De L'Isle studied at the French Maritime Ministry from 1700 to 1703, during which time he took extensive notes on the work of the Jesuit Missionaries, including Franquelin, Jolliet and others. Karpinksi notes that the fruits of De L'Isle's substantial efforts are born out by the great improvements in the mapping of the 5 Great Lakes and other parts of the map.

The information reported by Lahontan is in evidence in the Western part of the map, and discussed in a lengthy annotation. Excellent detail on the sources of the Mississippi and the regions around the Hudson and the Great Lakes. This is the scarce 4th State of the map, first issued in 1708, which removes Renard's name from the map.

Guillaume De L'Isle Biography

Guillaume De L'Isle (1675-1726) is probably the greatest figure in French cartography. Having learned geography from his father Claude, by the age of eight or nine he could draw maps to demonstrate ancient history.  He studied mathematics and astronomy under Cassini, from whom he received a superb grounding in scientific cartography—the hallmark of his work. His first atlas was published in ca. 1700. In 1702 he was elected a member of the Academie Royale des Sciences and in 1718 he became Premier Geographe du Roi

De L'Isle's work was important as marking a transition from the maps of the Dutch school, which were highly decorative and artistically-orientated, to a more scientific approach. He reduced the importance given to the decorative elements in maps, and emphasized the scientific base on which they were constructed. His maps of the newly explored parts of the world reflect the most up-to-date information available and did not contain fanciful detail in the absence of solid information. It can be fairly said that he was truly the father of the modern school of cartography at the commercial level. 

De L’Isle also played a prominent part in the recalculation of latitude and longitude, based on the most recent celestial observations. His major contribution was in collating and incorporating this latitudinal and longitudinal information in his maps, setting a new standard of accuracy, quickly followed by many of his contemporaries. Guillaume De L’Isle’s work was widely copied by other mapmakers of the period, including Chatelain, Covens & Mortier, and Albrizzi.
