Exploration
In the Pacific Ocean, Jorge de Menezes (c. 1498–?), discovered Papua New Guinea. García Jofre de Loaísa (1490–1526), discovered the Marshall Islands. Explorations of the Americas began with the initial discovery of America by Christopher Columbus (1451–1506), who led a Castilian (Spanish) expedition across the Atlantic, discovering America. After the discovery of America by Columbus, a number of important expeditions were sent out to explore the Western Hemisphere. This included Juan Ponce de León (1474–1521), who discovered and mapped the coast of Florida; Vasco Núñez de Balboa (c. 1475–1519), who was the first European to view the Pacific Ocean from American shores (after crossing the Isthmus of Panama) confirming that America was a separate continent from Asia; Aleixo Garcia (14?–1527), who explored the territories of present-day southern Brazil, Paraguay and Bolivia, crossing the Chaco and reaching the Andes (near Sucre).
Naming of the Americas
A Bristol antiquarian Alfred Hudd suggested in 1908 that the name was derived from the surname "Amerike" or "ap Meryk" and was used on early British maps that have since been lost. Richard ap Meryk, anglicised to Richard Amerike (or Ameryk) ( 1445–1503) was a wealthy English merchant, royal customs officer and sheriff of Bristol. According to some historians, he was the principal owner of the "Matthew", the ship sailed by John Cabot during his voyage of exploration to North America in 1497. The idea that Richard Amerike was a 'principal supporter' of Cabot has gained popular currency in the 21st century. There is no known evidence to support this. Similarly, and contrary to a recent tradition that names Amerike as principal owner and main funder of the "Matthew", Cabot's ship of 1497, academic enquiry does not connect Amerike with the ship. Her ownership at that date remains uncertain. Macdonald asserts that caravel was specifically built for the Atlantic crossing.
