and territorial claims. The decades from about 1535 to 1562 (when the Dieppe school of cartographers flourished) were also the period in which French trade with the New World was at its 16th-century height, in terms of the North Atlantic fish trade, the fur trade, and, most important for the cartographers, the rivalry with the Portuguese for control of the coasts of Brazil and the supplies of lucrative brazilwood. The bright red dye produced from brazilwood replaced woad as the primary dyestuff in the cloth industry in France and the Low Countries. The Dieppe cartographers used the skills and geographic knowledge of Portuguese mariners, pilots and geographers working in France to produce maps meant to emphasize French interests in and dominion over territory in the New World that the Portuguese also claimed, both in Newfoundland and in Brazil. Brunelle noted that, in design and decorative style the Dieppe maps represented a blending of the latest knowledge circulating in Europe with older visions of world geography deriving from Ptolemy and mediaeval cartographers and explorers such as Marco Polo. Renaissance mapmakers such as those based in Dieppe relied heavily on each other's work, as well as on maps from previous generations, and thus their maps represented a mixture of old and new information often coexisting uneasily in the same map. Robert J. King has also argued that Jave la Grande on the Dieppe maps reflects 16th-century cosmography. In a 2009 article, he pointed out that the geographers and map makers of the Renaissance struggled to bridge the gap from the world-view inherited from Graeco-Roman antiquity, as set out in Claudius Ptolemy's Geography, and a map of the world that would take account of the new geographical information obtained during the Age of Discoveries. The Dieppe world maps reflected the state of geographical knowledge of their time, both actual and theoretical. Accordingly, Java Major, or Jave la Grande, was shown as a promontory of the undiscovered antarctic continent of Terra Australis. This reflected a misunderstanding of where Marco Polo had located Java Minor and confusion regarding the relative positions of parts of East and Southeast Asia and America. In an argument similar to Brunelle's, King suggests that Jave la Grande on the Dieppe maps represents one of Marco Polo's pair of Javas (Major or Minor), misplaced far to the south of its actual location and attached to a greatly enlarged Terra Australis.
