In fact it was only in 1497, maybe five years after the discovery of America, that the southern point of Africa was passed by Vasco da Gama, and it may be affirmed that if this latter had preceded Columbus, the discovery of the new continent might have been delayed for several centuries. The navigators of this period were very timorous, and did not dare to sail out into mid-ocean; not liking to venture upon seas that were but little known, they always followed the coast-line of Africa, rather than go further from land. If the Cape of Tempests had been doubled, the sailors would have gone by this route to India, and none would have thought of going to the "Land of Spices," that is to say Asia, by venturing across the Atlantic. Who, in fact, would have thought of seeking for the east by the route to the west? But in truth this _was_ the great idea of that day, for Cooley says, "The principal object of Portuguese maritime enterprise in the fifteenth century was to search for a passage to India by the Ocean." The most learned men had not gone so far as to imagine the existence of another continent to complete the equilibrium and balance of the terrestrial globe. Some parts of the American continent had been already discovered, for an Italian navigator Sebastian Cabot had landed on Labrador in 1487, and the Scandinavians had certainly disembarked on this unknown land. The colonists of Greenland, too had explored Winland, but so little disposition was there at this time to believe in the existence of a new world, that Greenland, Winland, and Labrador were all thought to be a continuation of the European continent. The main question before the navigators of the fifteenth century was the opening up of an easier communication with the shores of Asia. The route to India, China, and Japan (countries already known through the wonderful narrative of Marco Polo), via, Asia Minor, Persia, and Tartary, was long and dangerous. The transport of goods was too difficult and costly for these "ways terrestrial" ever to become roads for commerce. A more practicable means of communication must be found. Thus all the dwellers on the coasts, from England to Spain, as well as the people living on the shores of the Mediterranean, seeing the great Atlantic ocean open to their vessels, began to inquire, whether indeed this new route might not conduct them to the shores of Asia. The sphericity of the Globe being established, this reasoning was correct, for going always westward, the traveller must necessarily at last reach the east, and as to the route across the ocean, it would certainly be open. Who could, indeed, have suspected the existence of an obstacle 9750 miles in length, lying between Europe and Asia, and called America?
