Desliens world map showing a portion of North America, ca. 1541.
In the middle of the 16th century French chart making was concentrated in Normandy and particularly in Dieppe. Nicholas Desliens' world map of 1541 was among the earliest productions of the Dieppe school. In addition to the 1541 map, two world maps created in 1566 and 1567 are also credited to Desliens.
