If Barros is correct in his deductions, it was not known on board of Cabral's fleet that Columbus had already discovered in the Paria region what he supposed an extension of the Asiatic main. The first conclusion of the Portuguese naturally was that they had stumbled either on a new group of islands, or perhaps on some outlying members of the group of the Antilles. Of course nothing was known at the time of the discoveries of Pinzon and Lepe.
The results of the African route.
It has often been remarked that if Columbus had not sailed in 1492, Cabral would have revealed America in 1500. It is a striking fact that the Portuguese had pursued their quest for India with an intelligence and prescience which geographical truth confirmed. The Spaniards went their way in error, and it took them nearly thirty years to find a route that could bring them where they could defend at the antipodes their rights under the Bull of Demarcation. Columbus sought India and found America without knowing it. Cabral, bound for the Cape of Good Hope, stumbled upon Brazil, and preëmpted the share of Portugal in the New World as Da Gama has already secured it in Asia. Thus the African route revealed both Cathay and America.
The Columbus lawsuit.
La Cosa's map, 1500.
For these voyages commingling with those of Columbus along the spaces of the Caribbean Sea, we get the best information, all things considered, from the testimonies of the participants in them, which were rendered in the famous lawsuit which the Crown waged against the heirs of Columbus. The well-known map of Juan de la Cosa posts us best on the cartographical results of these same voyages up to the summer of 1500.
