What did Amerigo Vespucci see and discover?

Answer 1

Amerigo Vespucci never discovered any lands himself. He was a map-maker and not an explorer. He did 'discover' that the lands that Columbus had found must be a continent by itself and not part of South East Asia. The circumference of the Earth was well known even before Columbus set out, as was the geografical location of India and China on the planet. That was the exact same reason why the Potuguese turned Columbus away: they knew that he was totally miscalculating the distance to China by a westward route. So it figures - and that was also what Vespucci figured - that a coast that is some 7,000 miles removed from China probably wasn't part of China.
