Beyond the limits he had vainly set ** The dullest sea-boat soon shall wing her way. Men shall descry another hemisphere, Since to one common center all things tend. So earth, by curious mystery divine * Life and Voyages of Columbus. ** Calpe and Abila, or Gibraltar, on the Spanish, and Cape Serra, on the African shore of the Straits of Gibraltar, were called the Pillars of Hercules; it being said, in ancient fable, that Hercules placed them there as monuments of his progress westward, and beyond which no mortal could pass. Well balanced, hangs amid the starry spheres. At our antipodes are cities, states, And thronged empires, ne'er divined of yore. But see, the sun speeds on his western path To glad the nations with expected light." Prescott's translation of stanza 229, 230, canto xxv. {xxi}While maturing his plans, Columbus extended the bounds of his observation and study by a voyage to Thule, or Iceland, from which remote point he says he advanced one hundred leagues northward, penetrated the polar circle, and convinced himself of the fallacy of the popular belief that the frozen zone was uninhabitable.1 Whether he saw, in Iceland, written accounts of the voyages of the Northmen to America, or heard of them as related by tradition or chanted in songs, we have no means of determining. If he did, it is singular, as Prescott remarks, that they were not cited by him in support of his hypothesis, while earnestly pressing his suit for aid before the courts of Portugal and Spain; and it is equally surprising that he did not, in his first voyage to America, pursue the route traversed by those early navigators. He probably heard little more than vague rumors of their voyages, such as presented insufficient data even for a plausible opinion. His magnificent idea was all his own, sustained by the opinions of a few learned men, and confirmed by his observations while on this northern voyage. Filled with his noble resolutions and lofty anticipations, Columbus submitted the theory on which rested his belief in a practicable western route to Asia, to King John the Second of Portugal. That monarch's sagacity perceived the promised advantages to be derived from such an enterprise, and he eagerly sought the counsel of his ministers and wise men. But his court and the college of scientific sages could not comprehend the sublime project; and after a long and fruitless negotiation, during which the Portuguese meanly attempted to avail themselves clandestinely of his information, Columbus quitted Lisbon in disgust, determined to submit his proposals to Ferdinand and Isabella, the Spanish sovereigns, whose wisdom and liberal views were the admiration of men of science and learning. His wife was dead; his feelings had no hold upon Portugal, and he quitted it forever.
