Martin Waldseemüller chose the name for his two maps of 1507 to
honor Amerigo Vespucci, whose writings about his voyages to America
between 1497 and 1504 were popular reading in Europe.
The modern viewer identifies this land quickly as South America.
But how did Waldseemüller six years before Vasco Núñez de Balboa
sighted the Pacific Ocean on 25 September 1513 and twelve years
before Ferdinand Magellan made his circumnavigation of the globe
in 1519-22 make such an accurate representation of South America?
And how was it that he depicted what appeared to be something
of both North and South America?
