Vespucci was in error respecting the remaining ships of the fleet engaged in his fourth voyage, for a few months later they came back to Lisbon in a shattered condition, but, so far as known, with their crews intact. They had sailed farther to the south than Vespucci went on this voyage, probably as far as the mouth of the great river La Plata, which Solis has the credit of discovering a few years later. It had been learned by that time that the coasts brought to view by the constantly lengthening voyages into the south were situated to the west of the great line of demarcation separating the discoveries of Spain and Portugal, and hence belonged to the former. This fact has a bearing upon the departure of Vespucci and other noted captains from Portugal about this time, as, if they would pursue these explorations to their logical conclusion, they must enlist beneath the banner of King Ferdinand. Hence we find our hero, towards the end of 1504, once again in Spain, and in high favor with the king.
The summer of 1504 Vespucci passed in Portugal, attending to matters connected with his last voyage, which had such an unsatisfactory ending; but in the latter part of that year we find him once again in Seville. It is presumed he was warmly welcomed by his wife, after this long absence of nearly four years; but nothing exists at all to indicate his marital relations, and so far as furnishing material for his biographers is concerned, he might as well have remained single all his life. In point of fact, Amerigo Vespucci, though sterling in his friendships, ardent and even affectionate, was a true celibate. He was wedded to Science, his whole nature was absorbed by the pursuits to which he had, perhaps fortuitously, devoted his maturer years. If we contrast him with Columbus, in respect to the higher qualities of his character, we cannot but be impressed by the difference between these two, for, while the latter was weak, impressionable, if not passionate, the former was strong, flawless in his morals, devoted ever to the star-eyed goddess in whose service he had enlisted for life.
He was humane, generous, unselfish, while Columbus, though of more heroic proportions than his rival, was at times selfish, ungenerous, cruel--as witness his treatment of the Pinzons, his claiming the reward for the discovery of land, which rightly belonged to Rodrigo de Triana, his massacres of Indians in Hispaniola and enslavement of the survivors. Against Amerigo Vespucci no such charges of immorality, cruelty, and bigotry can be brought as against Columbus, and the sole accusation against him, of falsifying the date of his "first" voyage, has not been sustained by the evidence.
