From Conquering The Pacific: An Unknown Mariner and the Final Great Voyage of the Age of Discovery, by Andrés Reséndez (HarperCollins, 2021), Kindle pp. 52-55:
Columbus’s exploits loom so large in our understanding of the past that other great discoveries recede into the background. In truth, any reasonable observer at the turn of the sixteenth century would have conceded that, even after Columbus’s famous voyages, Portugal’s lead in the global race had widened until becoming almost unassailable. Portuguese navigators reached the tip of Africa in 1488 and found the route to India a decade later. King Manuel I of Portugal took pleasure in writing lengthy letters to the Spanish monarchs, his in-laws and rivals, informing them, “Our Lord has miraculously wished India to be found” and telling them about the spices, precious stones, elephants, exotic peoples, and the immensely profitable trade carried on there. “We are still awaiting news from the twenty-five ships that we sent the previous year [1502],” Manuel gloated to Ferdinand and Isabella in one of his letters, “and after they come back in September there will be time to send some more.”
In the meantime, Spain could point to only a few Caribbean islands and inklings of an unknown continent, but no precious spices, porcelain, or silk. The new lands did offer some gold, but they never replaced the original quest of finding a western approach to the incalculable riches of the Far East. Spaniards explored the continent blocking their way, looking for a passage that would connect the Atlantic with the Pacific. They came up empty-handed until Fernão de Magalhães—a Portuguese defector like the Afro-Portuguese pilot Lope Martín a generation later—put Spain back in the race. Ferdinand Magellan had come of age during Portugal’s torrid expansion into Asia in the 1500s. Yet he had a falling-out with the Portuguese crown and went knocking on neighboring doors. It is difficult to overstate the significance of Magellan’s move to Spain.
Magellan caught up with the roving Spanish court at the town of Valladolid. For someone accustomed to the sound of waves and the proximity of sailboats, it must have been strange to have to journey to the middle of Iberia to propose a maritime venture in a town surrounded by agricultural fields and interminable plains. He did not arrive alone but was accompanied by two brothers, Rui and Francisco Faleiro, both cosmographers whose reputations exceeded Magellan’s. The trio complemented one another well. Magellan came across as a man of action who had fought in India, Malaysia, and North Africa, while the Faleiros were armchair academics. As they waited for an audience with the Spanish king in February and March of 1518, the Portuguese visitors grew unsettled by what they heard. The new monarch, Charles I, was an awkward eighteen-year-old who had come from Belgium just a few months before and had great difficulty communicating in Spanish let alone Portuguese. Worse, the trio had to tread carefully in a court riven by a power struggle between Charles’s advisers recently arrived from Belgium and the old Spanish officials from the previous monarch.
Interestingly, during the early negotiations Rui Faleiro rather than Magellan emerged as the leading voice. The older of the two Faleiro brothers, Rui was deferentially referred to as a bachiller (or bacharel in Portuguese), the highest university degree one could get at the time. Before leaving Portugal he may have been considered for a new chair in astronomy established at the oldest university in the kingdom (what is now the University of Coimbra) by the Portuguese king himself. It was the highest position in the field. One of the reasons that perhaps impelled Rui Faleiro to join Magellan in Spain was being passed over for this prestigious appointment; academic rivalries and pettiness were already alive and well in the sixteenth century! In spite of this setback, and notwithstanding a rumor that “he was possessed by a familial demon and in fact knew nothing about astrology,” Rui Faleiro remained a top European cosmographer. Sixteenth-century Spanish chronicler Gonzalo Fernández de Oviedo described Rui Faleiro as “a great man in matters of cosmography, astrology, and other sciences and humanities.” There is little doubt that he was extremely accomplished if mercurial and mentally unstable. Rui’s younger brother Francisco Faleiro was just as talented and would go on to find long-term employment in Spain as a leading nautical expert. Together the two Faleiros and Magellan were very credible petitioners.
On the day of the audience, Magellan and Rui Faleiro arrived not with charts as would have been expected but with “a globe that was very well painted and showed the entire world, and on it Magellan traced the route that he would follow.” The two petitioners explained that they intended to cross from one ocean to the other “through a certain strait that they already knew about.” Even though the globe was detailed, the portion of South America where the strait was supposed to be had been left intentionally blank. Magellan and Faleiro had evidently taken some precautions in case anyone present at the audience should wish to steal their project.
Their knowledge of a passage between the oceans—the alpha and omega of many New World explorations—would have been more than enough for the royal sponsorship. But Magellan and Faleiro went further. As one witness at the audience recounted, “They offered to demonstrate that the Moluccas [Spice Islands] from where the Portuguese take spices to their country are on the side of the world that belongs to Spain, as agreed by the Catholic Monarchs and King Juan of Portugal.” The 1494 Treaty of Tordesillas had established a line of demarcation running from pole to pole through the Atlantic but did not contemplate extending the line to the other side of the world. As Portugal and Spain, however, had continued to sail in opposite directions, such an antimeridian had become necessary. Measuring longitude or east-west distance was still extraordinarily difficult in the early sixteenth century, so no one knew quite where to draw this line in the distant Pacific. All the same, in the early 1510s the Portuguese had planted trading forts in Malaysia and the Spice Islands while Spain had stood by helplessly. Yet in the winter of 1518, Magellan and Faleiro had become persuaded that the Spice Islands were actually on the Spanish side, a conclusion all the more startling in Spain because it was coming from these top Portuguese navigators and cosmographers.
