While the Asiatic empire was built up by the sustained and patient effort of a nation, during seventy years, the discovery of the West was due to one eager and original intellect, propelled by medieval dreams. Columbus had sailed both North and South; but the idea which changed the axis of the globe came to him from books. He failed to draw an inference favourable to his design from the driftwood which a tropical current carries to Iceland, and proceeded on the assurance of Pierre d'Ailly and of Toscanelli, that Asia reaches so far east as to leave but a moderate interval between Portugal and Japan, Although he rested his case on arguments from the classics and the prophets, his main authority was Toscanelli; but it is uncertain whether, as he affirmed, they had been in direct correspondence, or whether Columbus obtained the letter and the Chart of 1474 by means which were the cause of his disgrace.
Rejected by Portugal, he made his way into Spain. He was found, starving, at the gate of a Franciscan convent; and the place where he sank down is marked by a monument, because it is there that our modern world began. The friar who took him in and listened to his story soon perceived that this ragged mendicant was the most extraordinary person he had known, and he found him patrons at the court of Castile. The argument which Columbus now laid before the learned men of Spain was this: The eastern route, even if the Portuguese succeed in finding it, would be of no use to them, as the voyage to Cipango, to Cathay, even to the spice islands, would be too long for profit. It was better to sail out into the West, for that route would be scarcely 3000 miles to the extremity of Asia; the other would be 15,000, apart from the tremendous circuit of Africa, the extent of which was ascertained by Diaz while Columbus was pursuing his uphill struggle. The basis of the entire calculation was that the circumference of the earth is 18,000 miles at the equator, and that Asia begins, as is shown in Toscanelli's chart, somewhere about California. Misled by his belief in cosmographers, he
