Vasco Núñez de Balboa
Vasco Núñez de Balboa (; c. 1475around January 12–21, 1519) was a Spanish explorer, governor, and conquistador. He is best known for having crossed the Isthmus of Panama to the Pacific Ocean in 1513, becoming the first European to lead an expedition to have seen or reached the Pacific from the New World.
Vasco de Lobeira
The query as to who authored Amadis de Gaula is further complicated by the fact that Vasco de Lobeira's name crops up in fifteenth and sixteenth century sources. The texts mention a Vasco de Lobeira receiving knighthood from King João I on the field of Aljubarrota, around 1385. But the first reference to Amadis de Gaula appears thirty-five years earlier, which would make Vasco over sixty years old when knighted or that he wrote his masterpiece in his youth. The only other possibility that remains is that 1350 reference was in fact to the poetic version by João de Lobeira.
