The Story of Geographical Discovery: How the World Became Known

by Joseph Jacobs

TO THE INDIES WESTWARD—THE SPANISH ROUTE—COLUMBUS AND MAGELLAN

While the Portuguese had, with slow persistency, devoted nearly a century to carrying out Prince Henry's idea of reaching the Indies by the eastward route, a bold yet simple idea had seized upon a Genoese sailor, which was intended to achieve the same purpose by sailing westward. The ancients, as we have seen, had recognised the rotundity of the earth, and Eratosthenes had even recognised the possibility of reaching India by sailing westward. Certain traditions of the Greeks and the Irish had placed mysterious islands far out to the west in the Atlantic, and the great philosopher Plato had imagined a country named Atlantis, far out in the Indian Ocean, where men were provided with all the gifts of nature. These views of the ancients came once more to the attention of the learned, owing to the invention of printing and the revival of learning, when the Greek masterpieces began to be made accessible in Latin, chiefly by fugitive Greeks from Constantinople, which had been taken by the Turks in 1453. Ptolemy's geography was printed at Rome in 1462, and with maps in 1478. But even without the maps the calculation which he had made of the length of the known world tended to shorten the distance between Portugal and Farther India by 2500 miles. Since his time the travels of Marco Polo had added to the knowledge of Europe the vast extent of Cathay and the distant islands of Zipangu (Japan), which would again reduce the distance by another 1500 miles. As the Greek geographers had somewhat under-estimated the whole circuit of the globe, it would thus seem that Zipangu was not more than 4000 miles to the west of Portugal. As the Azores were considered to be much farther off from the coast than they really were, it might easily seem, to an enthusiastic mind, that Farther India might be reached when 3000 miles of the ocean had been traversed.

TOSCANELLI'S MAP (restored)

This was the notion that seized the mind of Christopher Columbus, born at Genoa in 1446, of humble parentage, his father being a weaver. He seems to have obtained sufficient knowledge to enable him to study the works of the learned, and of the ancients in Latin translations. But in his early years he devoted his attention to obtaining a practical acquaintance with seamanship. In his day, as we have seen, Portugal was the centre of geographical knowledge, and he and his brother Bartolomeo, after many voyages north and south, settled at last in Lisbon—his brother as a map-maker, and himself as a practical seaman. This was about the year 1473, and shortly afterwards he married Felipa Moñiz, daughter of Bartolomeo Perestrello, an Italian in the service of the King of Portugal, and for some time Governor of Madeira.

Now it chanced just at this time that there was a rumour in Portugal that a certain Italian philosopher, named Toscanelli, had put forth views as to the possibility of a westward voyage to Cathay, or China, and the Portuguese king had, through a monk named Martinez, applied to Toscanelli to know his views, which were given in a letter dated 25th June 1474. It would appear that, quite independently, Columbus had heard the rumour, and applied to Toscanelli, for in the latter's reply he, like a good business man, shortened his answer by giving a copy of the letter he had recently written to Martinez. What was more important and more useful, Toscanelli sent a map showing in hours (or degrees) the probable distance between Spain and Cathay westward. By adding the information given by Marco Polo to the incorrect views of Ptolemy about the breadth of the inhabited world, Toscanelli reduced the distance from the Azores to 52°, or 3120 miles. Columbus always expressed his indebtedness to Toscanelli's map for his guidance, and, as we shall see, depended upon it very closely, both in steering, and in estimating the distance to be traversed. Unfortunately this map has been lost, but from a list of geographical positions, with latitude and longitude, founded upon it, modern geographers have been able to restore it in some detail, and a simplified sketch of it may be here inserted, as perhaps the most important document in Columbus's career.

Certainly, whether he had the idea of reaching the Indies by a westward voyage before or not, he adopted Toscanelli's views with enthusiasm, and devoted his whole life henceforth to trying to carry them into operation.

He gathered together all the information he could get about the fabled islands of the Atlantic—the Island of St. Brandan, where that Irish saint found happy mortals; and the Island of Antilla, imagined by others, with its seven cities. He gathered together all the gossip he could hear—of mysterious corpses cast ashore on the Canaries, and resembling no race of men known to Europe; of huge canes, found on the shores of the same islands, evidently carved by man's skill. Curiously enough, these pieces of evidence were logically rather against the existence of a westward route to the Indies than not, since they indicated an unknown race, but, to an enthusiastic mind like Columbus's, anything helped to confirm him in his fixed idea, and besides, he could always reply that these material signs were from the unknown island of Zipangu, which Marco Polo had described as at some distance from the shores of Cathay.

He first approached, as was natural, the King of Portugal, in whose land he was living, and whose traditional policy was directed to maritime exploration. But the Portuguese had for half a century been pursuing another method of reaching India, and were not inclined to take up the novel idea of a stranger, which would traverse their long-continued policy of coasting down Africa. A hearing, however, was given to him, but the report was unfavourable, and Columbus had to turn his eyes elsewhere. There is a tradition that the Portuguese monarch and his advisers thought rather more of Columbus's ideas at first; and attempted secretly to put them into execution; but the pilot to whom they entrusted the proposed voyage lost heart as soon as he lost sight of land, and returned with an adverse verdict on the scheme. It is not known whether Columbus heard of this mean attempt to forestall him, but we find him in 1487 being assisted by the Spanish Court, and from that time for the next five years he was occupied in attempting to induce the Catholic monarchs of Spain, Ferdinand and Isabella, to allow him to try his novel plan of reaching the Indies. The final operations in expelling the Moors from Spain just then engrossed all their attention and all their capital, and Columbus was reduced to despair, and was about to give up all hopes of succeeding in Spain, when one of the great financiers, a converted Jew named Luis de Santaguel, offered to find means for the voyage, and Columbus was recalled.
