Leif Erikson
Leif Erikson or Leif Ericson ( 970 – c. 1020) was a Norse explorer from Iceland. He was the first known European to have set foot on continental North America (excluding Greenland), before Christopher Columbus. According to the Sagas of Icelanders, he established a Norse settlement at Vinland, tentatively identified with the Norse L'Anse aux Meadows on the northern tip of Newfoundland in modern-day Canada. Later archaeological evidence suggests that Vinland may have been the areas around the Gulf of St. Lawrence and that the L'Anse aux Meadows site was a ship repair station.

The map's cartographer, Matteo Ricci, gave a brief description of the discovery of the Americas. "In olden days, nobody had ever known that there were such places as North and South America or Magellanica (using a name that early mapmakers gave to a supposed continent including Australia, Antarctica, and Tierra del Fuego), but a hundred years ago, Europeans came sailing in their ships to parts of the sea coast, and so discovered them."
