Professor Fiske, following Vespucci's ardent defender, the Viscount Varnhagen, deduces from the vague generalizations in this letter that the voyage was made chiefly along the Honduras, Yucatan, Mexican, and Florida coasts, as far north, perhaps, as Chesapeake Bay. The cannibals attacked by the Spaniards were found, he says, in the Bermudas--where no Indians were ever seen, so far as known, and no cannibals inhabit, save, perhaps, the great Shakespeare's "Caliban." He accounts for the lost voyage by declaring that it may have been taken with Pinzon and Solis, who were said to have been on the coast of Honduras in 1506. There is no certainty as to that date, and the voyage may as well have been made in 1497-1498, as indirectly shown by a passage in Oviedo's history, as follows: "Some persons have attributed the discovery of the bay of Honduras to Don Christopher Columbus, the first admiral; but this is not true, for it was discovered by the pilots Vicente Yañez Pinzon, Juan Diaz de Solis, and Pedro de Ledesma, with three caravels; and that was before Vicente Yañez had discovered the river Amazon."
The Amazon and a portion of the Brazil coast were discovered by Pinzon in January, 1500; and as the historian has proved to his own satisfaction that the gallant Vicente Yañez was in Spain during the years 1505 and 1506, it is probable that Oviedo is right. It is also probable, or at least possible, that Vespucci was with Pinzon on that Honduras voyage as consulting navigator, having been sent by the king, as he says, to "assist," in his capacity of astronomer and cosmographer. In this capacity, in fact, he went on all his voyages, for he rarely, if ever, held command. Captains, commanders, chief mates, and admirals there might be in plenty, but such a pilot and navigator as Vespucci was hard to find.
It is not unreasonable to presume that they were together, for the one was a skilful sailor, the other a great navigator, and both renowned for their hardihood and daring. King Ferdinand had no more loyal servants than these two, and as they had served him faithfully in their respective professions, the one on land, the other at sea, and inasmuch as both were intimately acquainted with Columbus and his plans, it was like the crafty old king to send them off to scour the seas his exacting "Admiral" claimed to control. Thereafter--whether Pinzon and Vespucci sailed together or not--their voyages alternated along the coast of South America, first one and then the other, and in 1505-1506 an expedition was actually projected, in which the king intended both should share. It did not sail, because the Portuguese objected, as its object was the exploration of the Brazilian coast south of the Tropic of Capricorn, to all which the great rivals of the Spaniards then made claim.
