 The world map published in the 1513 "Geography" seems to indicate that Waldseemüller had second thoughts about the name and the nature of the lands discovered in the western Atlantic.The New World was no longer clearly shown as a continent separate from Asia and the name America had been replaced with "Terra Incognita" (Unknown Land).What caused him to make these changes is not clear but perhaps he was influenced by contemporary criticism that Vespucci had usurped Columbus's primacy of discovery.
