We must in justice allow that certain facts gave, or seemed to give, reason to the partisans of Aristotle and Strabo for their belief in the proximity of the eastern shores. Thus, a pilot in the service of the King of Portugal, while sailing at 1350 miles' distance from Cape St. Vincent, the south-western point of the Portuguese province of Algarve, met with a piece of wood ornamented with ancient sculptures, which he considered must have come from a continent not far off. Again, some fishermen had found near the island of Madeira, a sculptured post and some bamboos, which in shape resembled those found in India. The inhabitants of the Azores also, often picked up gigantic pine-trees, of an unknown species, and one day two human bodies were cast upon their shores, "corpses with broad faces," says the chronicler Herrera, "and not resembling Christians."

These various facts tended to inflame imagination. As in the fifteenth century men had no knowledge of that great Gulf-stream, which, in nearing the European coasts, brings with it waifs and strays from America, so they could only imagine that these various débris must come from Asia. Therefore, they argued, Asia could not be far off, and the communication between these two extremes of the old continent must be easy. One point must be clearly borne in mind, no geographer of this period had any notion of the existence of a new world; it was not even a desire of adding to geographical knowledge which led to the exploration of the western route. It was the men of commerce who were the leaders in this movement, and who first undertook to cross the Atlantic. Their only thought was of traffic, and of carrying it on by the shortest road.

The mariner's compass, invented, according to the generally received opinion, about 1302, by one Flavio Gioja of Amalfi, enabled vessels to sail at a distance from the coasts, and to guide themselves when out of sight of land. Martin Béhaim, with two physicians in the service of Prince Henry of Portugal, had also added to nautical science by discovering the way of directing the voyager's course according to the position of the sun in the heavens, and by applying the astrolabe to the purposes of navigation. These improvements being adopted, the commercial question of the western route increased daily in importance in Spain, Portugal, and Italy, countries in which three-quarters of the science is made up of imagination. There was discussion, there were writings. The excited world of commerce disputed with the world of science. Facts, systems, doctrines, were grouped together. The time was come when there was needed one single intelligence to collect together and assimilate the various floating ideas. This intelligence was found. At length all the scattered notions were gathered together in the mind of one man, who possessed in a remarkable degree genius, perseverance, and boldness.

Christopher Columbus.

This man was no other than Christopher Columbus, born, probably near Genoa, about the year 1436. We say "probably," for the towns of Cogoreo and Nervi dispute with Savona and Genoa, the honour of having given him birth. The date of his birth varies, with different biographers, from 1430 to 1445, but the year 1436 would appear to be the correct one, according to the most reliable documents. The family of Columbus was of humble origin; his father, Domenic Columbus, a manufacturer of woollen stuffs, seems, however, to have been in sufficiently easy circumstances to enable him to give his children a more than ordinarily good education. The young Christopher, the eldest of the family, was sent to the University of Pavia, there to study Grammar, Latin, Geography, Astronomy, and Navigation.

At fourteen years of age Christopher left school and went to sea; from this time until 1487, very little is known of his career. It is interesting to give the remark of Humboldt on this subject, as reported by M. Charton; he said, "that he regretted the more this uncertainty about the early life of Columbus when he remembered all that the chroniclers have so minutely preserved for us upon the life of the dog Becerillo, or the elephant Aboulababat, which Haroun-al-Raschid sent to Charlemagne!" The most probable account to be gathered from contemporary documents and from the writings of Columbus himself, is that the young sailor visited the Levant, the west, the north, England several times, Portugal, the coast of Guinea, and the islands of Africa, perhaps even Greenland, for, by the age of forty "he had sailed to every part that had ever been sailed to before." He was looked upon as a thoroughly competent mariner, and his reputation led to his being chosen for the command of the Genoese galleys, in the war which that Republic was waging against Venice. He afterwards made an expedition, in the service of René, king of Anjou, to the coasts of Barbary, and in 1477, he went to explore the countries beyond Iceland.

This voyage being successfully terminated, Christopher Columbus returned to his home at Lisbon. He there married the daughter of an Italian gentleman, Bartolomeo Munez Perestrello, a sailor like himself and deeply interested in the geographical ideas of the day. The wife of Columbus, Dona Filippa, was without fortune, and Columbus, having none himself, felt he must work for the support of himself and his family. The future discoverer, therefore, set to work to make picture-books, terrestrial globes, maps, and nautical charts, and continued in this employment until 1481, but without at the same time abandoning his scientific and literary pursuits. It seems probable even, that during this period he studied deeply, and attained to knowledge far beyond that possessed by most of the sailors of his time. Can it have been that at this time "the Great Idea" first arose in his mind? It may well have been so. He was following assiduously the discussions relative to the western routes, and the facility of communication by the west, between Europe and Asia. His correspondence proves that he shared the opinion of Aristotle as to the relatively short distance separating the extreme shores of the old Continent. He wrote frequently to the most distinguished savants of his time. Martin Béhaim, of whom we have already spoken, was amongst his correspondents, and also the celebrated Florentine astronomer, Toscanelli, whose opinions in some degree influenced those of Columbus.
