Importance of spices in encouraging navigation.
There is no doubt that the desire to obtain spices was the main reason for the exploration of the globe. This motive led European navigators to try in succession every possible way to reach the East—by going around Africa, by sailing west in the hope of reaching the Indies, before they knew of the existence of America; then, after America was discovered, by sailing around it to the north or south, and even sailing around Europe to the north. It is hard for us to understand this enthusiasm for spices, for which we care much less nowadays. One former use of spices was to preserve food, which could not then as now be carried rapidly, while still fresh, from place to place; nor did our conveniences then exist for keeping it by the use of ice. Moreover, spice served to make even spoiled food more palatable than it would otherwise have been.
The Voyages of Discovery
Idea of reaching the spice islands by sailing westward.
It inevitably occurred to thoughtful men that the East Indies could be reached by sailing westward. The chief authority upon the form and size of the earth was still the ancient astronomer, Ptolemy, who lived about A.D. 150. He had reckoned the earth to be about one sixth smaller than it is; and as Marco Polo had given an exaggerated idea of the distance which he and his companions had traveled eastward, it was supposed that it could not be a very long journey from Europe across the Atlantic to Japan.
Columbus discovers America, 1492.
The first plan for sailing west was, perhaps, submitted to the Portuguese king in 1474, by Toscanelli, a Florentine physician. In 1492, as we all know, a Genoese navigator, Columbus (b. 1451), who had had much experience on the sea, got together three little ships and undertook the journey westward to Zipangu, which he hoped to reach in five weeks. After thirty-two days from the time he left the Canary Islands he came upon land, the island of San Salvador, and believed himself to be in the East Indies. Going on from there he discovered the island of Cuba, which he believed to be the mainland of Asia, and then Haiti, which he mistook for the longed-for Zipangu. Although he made three later expeditions and sailed down the coast of South America as far as the Orinoco, he died without realizing that he had not been exploring the coast of Asia.[247]
