In the ever-memorable month of October, 1492, Christopher Columbus landed on the shores of the New World he had discovered by sailing westward. To this great undertaking Columbus had advanced through a long career during which he had had unusual adventures and experiences in almost every part of the known world. A Genoese by birth, he had studied at Pavia,(5) where he had acquired some knowledge of Latin, and was introduced to the study of those sciences to which his inclinations and his opportunities enabled him later to devote himself. He knew the Atlantic Coast from El Mina in Africa,(6) to England and Iceland,(7) and he had visited the Levant(8)and the islands of the Grecian Archipelago. Writing of himself to the Catholic sovereigns, he says that he had been a sailor from his earliest youth, and curious to discover the secrets of the world. This same impulse led him to the study of navigation, cosmography, and kindred sciences, and his son Ferdinand states that the book which most influenced his father was the _Cosmographia_ of Cardinal Aliaco in which he read the following passage: Et dicit Aristoteles ut mare parvum est inter finem Hispanicæ a parte Occidentis, et inter principium Indiæ a parte Orientis. Et non loquitur de Hispaniâ citeriori quæ nunc Hispania communiter dicitur sed de Hispaniâ ulteriori quæ nunc Africa dicitur.(9) The illustrious Florentine, Paolo Toscanelli, definitely encouraged the conviction Columbus had formed from his reading of Marco Polo’s descriptions of Cipango, Cathay, and the Grand Khan, that the lands might be reached by sailing west, and there was doubtless little the ancients had written concerning the existence of islands and continents lying beyond the Pillars of Hercules with which he was not acquainted. The story of his attempts to secure the necessary means and authority for undertaking his great enterprise does not belong to our present subject, but before hearing his own description of what and whom he found in the western hemisphere when first he landed there, it is necessary to consider the arguments by which his friends finally prevailed on the sovereigns of Castile to grant him their patronage. That they did this contrary to the the counsels of the learned cosmographers of the age and in defiance of contemporary common-sense, is in itself a most noteworthy fact which testifies both to the singular qualities of Columbus and to the rare sagacity of the Catholic Queen who, in her momentous decision, acted alone, there being little in the scheme to commend it to the colder temperament of King Ferdinand.
