And although there was a somewhat doubtful rumour afloat, that the Portuguese had advanced so far to the east, that they had come to the end of their own limits, and had passed over into the territory appointed for the Castilians, and that Malacca and the Great Gulf were within our limits, all this was more said than believed, until, four years ago, Ferdinand Magellan, a distinguished Portuguese, who had for many years sailed about the Eastern Seas as admiral of the Portuguese fleet, having quarreled with his king, who he considered had acted ungratefully towards him, and Christopher Haro, brother of my father-in-law, of Lisbon, who had, through his agents for many years carried on trade with those eastern countries, and more recently with the Chinese, so that he was well acquainted with these matters (he also, having been ill-used by the King of Portugal, had returned to his native country, Castille), pointed out to the emperor, that it was not yet clearly ascertained, whether Malacca was within the boundaries of the Portuguese or of the Castillians, because hitherto its longitude had not been definitely known; but that it was an undoubted fact that the Great Gulf and the Chinese nations were within the Castilian limits They asserted also that it was absolutely certain, that the islands called the Moluccas, in which all sorts of spices grow, and from which they were brought to Malacca, were contained in the western, or Castilian division, and that it would be possible to sail to them, and to bring the spices at less trouble and expense from their native soil to Castille.  The plan of the voyage was to sail west, and then coasting the Southern Hemisphere round the south of America to the east.  Yet it appeared to be a difficult undertaking, and one of which the practicability was doubtful.  Not that it was impossible, prima facie, to sail from the west round the Southern Hemisphere to the east; but that it was uncertain, whether ingenious Nature, all whose works are wisely conceived, had so arranged the sea and the land that it might be possible to arrive by this course at the Eastern Seas.  For it had not been ascertained whether that extensive region, which is called Terra Firma, separated the Western Ocean [the Atlantic] from the Eastern [the Pacific]; but it was plain that that continent extended in a southerly direction, and afterwards inclined to the west.  Moreover two regions had been discovered in the north, one called Baccalearum from a new kind of fish, [223] the other called Florida; and if these were connected with Terra Firma, it would not be possible to pass from the Western Ocean to the Eastern; since although much trouble had been taken to discover any strait which might exist connecting the two oceans, none had yet been found.  At the same time it was considered that to attempt to sail through the Portuguese concessions and the Eastern Seas would be a hazardous enterprise, and dangerous in the highest degree.
