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).
Globus Jagellonicus
Robert J. King has pointed out that America was shown on the Jagiellonian Globe in two locations: in the Atlantic Ocean under the names and ; and in the Indian Ocean under the name (America newly discovered). The phrase, "america noviter reperta" was used for the first time in the booklet, "Globus Mundi: Declaratio sive descriptio mundi et totius orbis terrarum," published in Strassburg by J. Grüninger in 1509.
