Fine, French map of the region to the east of Lyon and the Rhone River, extending into Piedmont, in Italy, and the start of Switzerland.

The map utilizes Latin toponyms for some of the features shown on the map. For example, Lyon, at the confluence of the Saone and Rhone, is named Lugdunum. Other cities shown include Geneva, Turin (Taurinin), and Grenoble (Gratianopolis).

The map includes fine detail showing mountains pictorially as well as rivers, and many other features. Double crosses and single crosses over cities reflect centers of the church, while a tilted cross symbol (indicated in the legend) shows Carthusian monasteries. 

This map was published in Paris by Guillaume de L'Isle at the start of the 18th century. 

Condition Description
Original hand-color, in outline. Dampstains at top of map. Burn mark in lower left. Slight loss just past neatline in lower left and lower right corners.
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.
