The Life of Christopher Columbus from his own Letters and Journals | Page 6

seems to be good foundation for the story.
It seems. clear that, from the time when he arrived in Lisbon, for more than twenty years, he was at work trying to interest people in his "great design," of western discovery. He says himself, "I was constantly corresponding with learned men, some ecclesiastics and some laymen, some Latin and some Greek, some Jews and some Moors." The astronomer Toscanelli was one of these correspondents.
We must not suppose that the idea of the roundness of the earth was invented by Columbus. Although there were other theories about its shape, many intelligent men well understood that the earth was a globe, and that the Indies, though they were always reached from Europe by going to the East, must be on the west of Europe also. There is a very funny story in the travels of Mandeville, in which a traveler is represented as having gone, mostly on foot, through all the countries of Asia, but finally determines to return to Norway, his home. In his farthest eastern investigation, he hears some people calling their cattle by a peculiar cry, which he had never heard before. After he returned home, it was necessary for him to take a day's journey westward to look after some cattle he had lost. Finding these cattle, he also heard the same cry of people calling cattle, which he had heard in the extreme East, and now learned, for the first time, that he had gone round the world on foot, to turn and come back by the same route, when he was only a day's journey from home, Columbus was acquainted with such stories as this, and also had the astronomical knowledge which almost made him know that the world was round, "and, like a ball, goes spinning in the air." The difficulty was to persuade other people that, because of this roundness, it would be possible to attain Asia by sailing to the West.
Now all the geographers of repute supposed that there was not nearly so large a distance as there proved to be, in truth, between Europe and Asia. Thus, in the geography of Ptolemy, which was the standard book at that time, one hundred and thirty-five degrees, a little more than one-third of the earth's circumference, is given to the space between the extreme eastern part of the Indies and the Canary Islands. In fact, as we now know, the distance is one hundred and eighty degrees, half the world's circumference. Had Columbus believed there was any such immense distance, he would never have undertaken his voyage.
Almost all the detailed knowledge of the Indies which the people of his time had, was given by the explorations of Marco Polo, a Venetian traveler of the thirteenth century, whose book had long been in the possession of European readers. It is a very entertaining book now, and may well be recommended to young people who like stories of adventure. Marco Polo had visited the court of the Great Khan of Tartary at Pekin, the prince who brought the Chinese Empire into very much the condition in which it now is. He had, also, given accounts of Japan or Cipango, which he had himself never visited. Columbus knew, therefore, that, well east of the Indies, was the island of Cipango, and he aimed at that island, because he supposed that that was the nearest point to Europe, as in fact it is. And when finally he arrived at Cuba, as the reader will see, he thought he was in Japan.
Columbus's father-in-law had himself been the Portuguese governor of the island of Porto Santo, where he had founded a colony. He, therefore, was interested in western explorations, and probably from him Columbus collected some of the statements which are known to have influenced him, with regard to floating matters from the West, which are constantly borne upon that island by the great currents of the sea.
The historians are fond of bringing together all the intimations which are given in the Greek and Latin classics, and in later authors, with regard to a land beyond Asia. Perhaps the most famous of them is that of Seneca, "In the later years there shall come days in which Ocean shall loose his chains, and a great land shall appear . . . and Thule shall not be the last of the worlds."
In a letter which Toscanelli wrote to Columbus in 1474, he inclosed a copy of a letter which he had already sent to an officer of Alphonso V, the King of Portugal. In writing to Columbus, he says, "I see that you have a great and noble desire to go into that country (of the East) where the spices come from, and in reply to your letter I send you a copy
