Vespucci's first voyage left Spain on May 10, 1497, and according to one of his letters, he may actually have discovered Venezuela before Columbus did. His 1499 voyage took him to the coast of modern Guyana and went on to explore the coast of Brazil, becoming the first European to see the Amazon River. His 1501 voyage was in service of Portugal instead of Spain, and the trip explored the South American coast from Cape Sao Roque down south to Patagonia, discovering what would later be Rio de Janeiro. It was in a letter that Vespucci described South America as "the New World."
