of it was to be descried. When it did appear, however, it was always in the same place, and under the same form. So persuaded were the inhabitants of the Canaries of its reality, that application was made to the king of Portugal for permission to discover and take possession of it; and it actually became the object of several expeditions. The island, however, was never to be found, though it still continued occasionally to cheat the eye.

There were all kinds of wild and fantastic notions concerning this imaginary land. Some supposed it to be the Antilla mentioned by Aristotle; others, the Island of Seven Cities, so called from an ancient legend of seven bishops, who, with a multitude of followers, fled from Spain, at the time of its conquest by the Moors, and, guided by Heaven to some unknown island in the ocean, founded on it seven splendid cities; while some considered it another legendary island, on which, it was said, a Scottish priest of the name of St. Brandan had landed, in the sixth century. This last legend past into current belief. The fancied island was called by the name of St. Brandan, or St. Borondon, and long continued to be actually laid down in maps far to the west of the Canaries. The same was done with the fabulous island of Antilla; and these erroneous maps, and phantom islands, have given rise, at various times, to assertions that the New World had been known prior to the period of its generally reputed discovery.

Columbus, however, considers all these appearances of land as mere illusions. He supposes

that they may have been caused by rocks lying in the ocean, which, seen at a distance, under certain atmospherical influences, may have assumed the appearance of islands; or that they may have been floating islands, such as are mentioned by Pliny and Seneca and others, formed of twisted roots, or of a light and porous stone, and covered with trees, and which may have been driven about the ocean by the winds.

The islands of St. Brandan, of Antilla, and of the Seven Cities, have long since proved to be fabulous tales, or atmospherical delusions. Yet the rumors concerning them derive interest, from showing the state of public thought with respect to the Atlantic, while its western regions were yet unknown. They were all noted down with curious care by Columbus, and may have had some influence over his imagination. Still, though of a visionary spirit, his penetrating genius sought in deeper sources for the aliment of its meditations. Aroused by the impulse of passing events, he turned anew, says his son Fernando, to study the geographical authors which he had read before, and to consider the astronomical reasons which might corroborate the theory gradually forming in his mind. He made himself acquainted with all that had been written by the ancients, or discovered by the moderns, relative to geography. His own voyages enabled him to correct many of their errors, and appreciate many of their theories. His genius having

thus taken its decided bent, it is interesting to notice from what a mass of acknowledged facts, rational hypotheses, fanciful narrations, and popular rumors, his grand project of discovery was wrought out by the strong workings of his vigorous mind.

T has been attempted, in the preceding chapters, to show how Columbus was gradually kindled up to his grand design by the spirit and events of the times in which he lived. His son Fernando, however, undertakes to furnish the precise data on which his father's plan of discovery was founded.1 "He does this," he observes, " to show from what slender argument so great a scheme was fabricated and brought to light; and for the purpose of satisfying those who may desire to know distinctly the circumstances and motives which led his father to undertake this enterprise."

As this statement was formed from notes and documents found among his father's papers, it is too curious and interesting, not to deserve particular mention. In this memorandum he arranged the foundation of his father's theory under three heads: 1. The nature of things. 2. The authority of learned writers. 3. The reports of navigators.

LIFE AND VOYAGES OF COLUMBUS. 43

Under the first head, he set down as a fundamental principle, that the earth was a terraqueous sphere or globe, which might be travelled round from east to west, and that men stood foot to foot, when on opposite points. The circumference from east to west, at the equator, Columbus divided, according to Ptolemy, into twentyfour hours of fifteen degrees each, making three hundred and sixty degrees. Of these he imagined, comparing the globe of Ptolemy with the earlier map of Marinus of Tyre, that fifteen hours had been known to the ancients, extending from the Straits of Gibraltar, or rather from the Canary Islands, to the city of Thine in Asia, a place set down as at the eastern limits of the known world. The Portuguese had advanced the western frontier one hour more by the discovery of the Azores and Cape de Verde Islands. There remained, then, according to the estimation of Columbus, eight hours, or one-third of the circumference of the earth, unknown and unexplored. This space might, in a great measure, be filled up by the eastern regions of Asia, which might extend so far as nearly to surround the globe, and to approach the western shores of Europe and Africa. The tract of ocean, intervening between these countries, he observes, would be less than might at first be supposed, if the opinion of Alfraganus, the Arabian, were admitted, who, by diminishing the size of the degrees, gave to the earth a smaller circumference than did other cosmographers; a theory to which Columbus seems at times to have given faith.
