The calculations of the longitude showed that these islands were well within the Spanish half of the world and the success with which a Malay slave of Magellan, brought from Sumatra, made himself understood [15] indicated clearly enough that they were not far from the Moluccas and that the object of the expedition, to discover a westward route to the Spice Islands, and to prove them to be within the Spanish demarcation, was about to be realized. But Magellan, like Moses, was vouchsafed only a glimpse of the Promised Land. That the heroic and steadfast navigator should have met his death in a skirmish with a few naked savages when in sight of his goal, is one of the most pathetic tragedies in history. [16] The difficulties, however, of approaching the Moluccas by the western route through the straits of Magellan (that Cape Horn could be rounded was not discovered till 1616), the stubborn and defiant attitude of the King of Portugal in upholding his claims, the impossibility of a scientific and exact determination of the Demarcation Line in the absence of accurate means for measuring longitude,--all these, reinforced by the pressure of financial stringency led King Charles in 1529 to relinquish all claims to or rights to trade with the Moluccas for three hundred and fifty thousand ducats. [17] In the antipodes a Demarcation Line was to be drawn from pole to pole seventeen degrees on the equator, or two hundred and ninety-seven leagues east of the Moluccas, and it was agreed that the subjects of the King of Castile should neither sail or trade beyond that line, or carry anything to the islands or lands within it. [18] If a later scientific and accurate determination should substantiate the original claims of either party the money should be returned [19] and the contract be dissolved. Although the archipelago of St. Lazarus was not mentioned in this treaty it was a plain renunciation of any rights over the Philippines for they lie somewhat to the west of the Moluccas. The King of Spain, however, chose to ignore this fact and tacitly assumed the right to conquer the Philippines. It was, however, thirteen years before another attempt was made in this direction. By this time the conquest and development of the kingdom of New Spain made one of its ports on the Pacific the natural starting point. This expedition commanded by Rui Lopez de Villalobos was despatched in 1542 and ended disastrously. The Portuguese Captain-general in the Moluccas made several vigorous protests against the intrusion, asserting that Mindanao fell within the Portuguese Demarcation and that they had made some progress in introducing Christianity. [20] Villalobos left no permanent mark upon the islands beyond giving the name "Felipinas" to some of them, in honor of "our fortunate Prince." [21]
