Handsome Lake
How America Was Discovered  is a story told by Handsome Lake, and documented by Arthur C. Parker, about a young minister who meets the one he perceives to be the Lord, who then asks him to go to a new land and bring with him cards, money, a fiddle, whiskey, and blood corruption. In return the young minister will become rich. The young minister sought out Christopher Columbus, and with the help of his crew, traveled to the Americas. They turned back to report what they had seen, which caused an immigration of people from Europe to the Americas. Along with the people came the five things that aided in destroying the natives. The end reveals that the "Lord" in the gold castle was actually the devil, and that even he knew what he had caused was wrong.
Leif Erikson
According to a literal interpretation of Einar Haugen's translation of the two sagas in the book "Voyages to Vinland", Leif was not the first European to discover America: he had heard the story of merchant Bjarni Herjólfsson who claimed to have sighted land to the west of Greenland after having been blown off course. Bjarni reportedly never made landfall there, however. Later, when travelling from Norway to Greenland, Leif was also blown off course, to a land that he did not expect to see, where he found "self-sown wheat fields and grapevines". He next rescued two men who were shipwrecked in this country and went back to Greenland (and Christianised the people there). Consequently, if this is to be trusted, Bjarni Herjólfsson was the first European to see America beyond Greenland, and the two unnamed shipwrecked men were the first people known to Europeans to have made landfall there.
