SKETCH FROM A PORTOLANO IN THE BRITISH MUSEUM.
John Rotz's map.
John Rotz's Boke of Idiography—a manuscript of 1542, preserved in the British Museum—shows, in his drawing of the region about the Gulf of St. Lawrence, certain signs, as Kohl thinks, of having had access to the charts of Cartier, and Harrisse traces in them the combined influence of the Portuguese and Dieppe navigators.
The Cartier voyages seem to have made little impression outside of France, and we find for some years few traces of his discoveries in the portolanos of Italy and in the maps of the rest of Europe. It was only when the expedition of Roberval, in 1540-41, excited attention that the rest of Europe seemed to recognize these French efforts.
