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.
New World
The Italian-born Spanish chronicler Peter Martyr d'Anghiera often shares credit with Vespucci for designating the Americas as a new world. Peter Martyr used the term "Orbe Novo" (literally, "New Globe", but often translated as "New World") in the title of his history of the discovery of the Americas as a whole, which began to appear in 1511 (cosmologically, "orbis" as used here refers to the whole hemisphere, while "mundus" refers to the land within it). Peter Martyr had been writing and circulating private letters commenting on Columbus's discoveries since 1493 and, from the start, doubted Columbus's claims to have reached East Asia ("the Indies"), and consequently came up with alternative names to refer to them. Only a few weeks after Columbus's return from his first voyage, Peter Martyr wrote letters referring to Columbus's discovered lands as the "western antipodes" ("antipodibus occiduis", letter of May 14, 1493), the "new hemisphere of the earth" ("novo terrarum hemisphaerio", September 13, 1493), and in a letter dated November 1, 1493, refers to Columbus as the "discoverer of the new globe" ("Colonus ille novi orbis repertor"). A year later (October 20, 1494), Peter Martyr again refers to the marvels of the New Globe ("Novo Orbe") and the "Western hemisphere."("ab occidente hemisphero").
