On the 3d of May, 1493, he published a bull, in which, taking into consideration the eminent services of the Spanish monarchs in the cause of the church, especially in the subversion of the Mahometan empire in Spain, and willing to afford still wider scope for the prosecution of their pious labors, he, "out of his pure liberality, infallible knowledge, and plenitude of apostolic power," confirmed them in the possession of all lands discovered or hereafter to be discovered by them in the western ocean, comprehending the same extensive rights of jurisdiction with those formerly conceded to the kings of Portugal.
This bull he supported by another, dated on the following day, in which the pope, in order to obviate any misunderstanding with the Portuguese, and acting no doubt on the suggestion of the Spanish sovereigns, defined with greater precision the intention of his original grant to the latter, by bestowing on them all such lands as they should discover to the west and south of an imaginary line, to be drawn from pole to pole, at the distance of one hundred leagues to the west of the Azores and Cape de Verd Islands. [20] It seems to have escaped his Holiness, that the Spaniards, by pursuing a western route, might in time reach the eastern limits of countries previously granted to the Portuguese. At least this would appear from the import of a third bull, issued September 25th of the same year, which invested the sovereigns with plenary authority over all countries discovered by them, whether in the east, or within the boundaries of India, all previous concessions to the contrary notwithstanding. With the title derived from actual possession, thus fortified by the highest ecclesiastical sanction, the Spaniards might have promised themselves an uninterrupted career of discovery, but for the jealousy of their rivals, the Portuguese. [21]
The court of Lisbon viewed with secret disquietude the increasing maritime enterprise of its neighbors. While the Portuguese were timidly creeping along the barren shores of Africa, the Spaniards had boldly launched into the deep, and rescued unknown realms from its embraces, which teemed in their fancies with treasures of inestimable wealth. Their mortification was greatly enhanced by the reflection, that all this might have been achieved for themselves, had they but known how to profit by the proposals of Columbus. [22] From the first moment in which the success of the admiral's enterprise was established, John the Second, a politic and ambitious prince, had sought some pretence to check the career of discovery, or at least to share in the spoils of it. [23]
In his interview with Columbus, at Lisbon, he suggested, that the discoveries of the Spaniards might interfere with the rights secured to the Portuguese by repeated papal sanctions since the beginning of the present century, and guaranteed by the treaty with Spain, in 1479. Columbus, without entering into the discussion, contented himself with declaring, that he had been instructed by his own government to steer clear of all Portuguese settlements on the African coast, and that his course indeed had led him in an entirely different direction. Although John professed himself satisfied with the explanation, he soon after despatched an ambassador to Barcelona, who, after dwelling on some irrelevant topics, touched, as it were, incidentally on the real object of his mission, the late voyage of discovery. He congratulated the Spanish sovereigns on its success; expatiated on the civilities shown by the court of Lisbon to Columbus, on his late arrival there; and acknowledged the satisfaction felt by his master at the orders given to the admiral, to hold a western course from the Canaries, expressing a hope that the same course would be pursued in future, without interfering with the rights of Portugal by deviation to the south. This was the first occasion, on which the existence of such claims had been intimated by the Portuguese.
In the mean while, Ferdinand and Isabella received intelligence that King John was equipping a considerable armament in order to anticipate or defeat their discoveries in the west. They instantly sent one of their household, Don Lope de Herrera, as ambassador to Lisbon, with instructions to make their acknowledgments to the king for his hospitable reception of Columbus, accompanied with a request that he would prohibit his subjects from interference with the discoveries of the Spaniards in the west, in the same manner as these latter had been excluded from the Portuguese possessions in Africa. The ambassador was furnished with orders of a different import, provided he should find the reports correct, respecting the equipment and probable destination of a Portuguese armada. Instead of a conciliatory deportment, he was, in that case, to assume a tone of remonstrance, and to demand a full explanation from King John, of his designs. The cautious prince, who had received, through his secret agents in Castile, intelligence of these latter instructions, managed matters so discreetly as to give no occasion for their exercise. He abandoned, or at least postponed, his meditated expedition, in the hope of adjusting the dispute by negotiation, in which he excelled. In order to quiet the apprehensions of the Spanish court, he engaged to fit out no fleet from his dominions within sixty days; at the same time he sent a fresh mission to Barcelona, with directions to propose an amicable adjustment of the conflicting claims of the two nations, by making the parallel of the Canaries a line of partition between them; the right of discovery to the north being reserved to the Spaniards, and that to the south to the Portuguese. [24]
While this game of diplomacy was going on, the Castilian court availed itself of the interval afforded by its rival, to expedite preparations for the second voyage of discovery; which, through the personal activity of the admiral, and the facilities everywhere afforded him, were fully completed before the close of September. Instead of the reluctance, and indeed avowed disgust, which had been manifested by all classes to his former voyage, the only embarrassment now arose from the difficulty of selection among the multitude of competitors, who pressed to be enrolled in the present expedition. The reports and sanguine speculations of the first adventurers had inflamed the cupidity of many, which was still further heightened by the exhibition of the rich and curious products which Columbus had brought back with him, and by the popular belief that the new discoveries formed part of that gorgeous east,
"whose caverns teem With diamond flaming, and with seeds of gold,"
and which tradition and romance had alike invested with the supernatural splendors of enchantment. Many others were stimulated by the wild love of adventure, kindled in the long Moorish war, but which, now excluded from that career, sought other objects in the vast, untravelled regions of the New World. The complement of the fleet was originally fixed at twelve hundred souls, which, through importunity or various pretences of the applicants, was eventually swelled to fifteen hundred. Among these were many who enlisted without compensation, including several persons of rank, hidalgos, and members of the royal household. The whole squadron amounted to seventeen vessels, three of them of one hundred tons' burden each. With this gallant navy, Columbus, dropping down the Guadalquivir, took his departure from the bay of Cadiz, on the 25th of September, 1493; presenting a striking contrast to the melancholy plight, in which, but the year previous, he sallied forth like some forlorn knight-errant, on a desperate and chimerical enterprise. [25]
No sooner had the fleet weighed anchor, than Ferdinand and Isabella despatched an embassy in solemn state to advise the king of Portugal of it. This embassy was composed of two persons of distinguished rank, Don Pedro de Ayala, and Don Garci Lopez de Carbajal. Agreeably to their instructions, they represented to the Portuguese monarch the inadmissibility of his propositions respecting the boundary line of navigation; they argued that the grants of the Holy See, and the treaty with Spain in 1479, had reference merely to the actual possessions of Portugal, and the right of discovery by an eastern route along the coasts of Africa to the Indies; that these rights had been invariably respected by Spain; that the late voyage of Columbus struck into a directly opposite track; and that the several bulls of Pope Alexander the Sixth, prescribing the line of partition, not from east to west, but from the north to the south pole, were intended to secure to the Spaniards the exclusive right of discovery in the western ocean. The ambassadors concluded with offering, in the name of their sovereigns, to refer the whole matter in dispute to the arbitration of the court of Rome, or of any common umpire.
King John was deeply chagrined at learning the departure of the Spanish expedition. He saw that his rivals had been acting while he had been amused with negotiation. He at first threw out hints of an immediate rupture; and endeavored, it is said, to intimidate the Castilian ambassadors, by bringing them accidentally, as it were, in presence of a splendid array of cavalry, mounted and ready for immediate service. He vented his spleen on the embassy, by declaring, that "it was a mere abortion; having neither head nor feet;" alluding to the personal infirmity of Ayala, who was lame, and to the light, frivolous character of the other envoy.
