The Cartier-Roberval voyages (pl 33) greatly enlarged European knowledge of northeastern North America, and enabled cartographers to represent the complex shoreline of the Gulf of St Lawrence with some accuracy. This map by Pierre Desceliers, a cartographer-artist working near Dieppe, illustrates the great expansion of geographical understanding since pre-Cartier days. The delightful illustrations are largely fanciful.
