The object of the great navigator was still the discovery of a route to India, but by the west instead of the east. He had no expectation of meeting with a continent in his way, and, after repeated voyages, he remained in his original error, dying, as is well known, in the conviction that it was the eastern shore of Asia which he had reached. It was the same object which directed the nautical enterprises of those who followed in the Admiral's track; and the discovery of a strait into the Indian Ocean was the burden of every order from the government, and the design of many an expedition to different points of the new continent, which seemed to stretch its leviathan length along from one pole to the other. The discovery of an Indian passage is the true key to the maritime movements of the fifteenth and the first half of the sixteenth centuries. It was the great leading idea that gave the character to the enterprise of the age. It is not easy at this time to comprehend the impulse given to Europe by the discovery of America. It was not the gradual acquisition of some border territory, a province or a kingdom that had been gained, but a New World that was now thrown open to the European. The races of animals, the mineral treasures, the vegetable forms, and the varied aspects of nature, man in the different phases of civilization, filled the mind with entirely new sets of ideas, that changed the habitual current of thought and stimulated it to indefinite conjecture. The eagerness to explore the wonderful secrets of the new hemisphere became so active, that the principal cities of Spain were, in a manner, depopulated, as emigrants thronged one after another to take their chance upon the deep. *2 It was a world of romance that was thrown open; for, whatever might be the luck of the adventurer, his reports on his return were tinged with a coloring of romance that stimulated still higher the sensitive fancies of his countrymen, and nourished the chimerical sentiments of an age of chivalry. They listened with attentive ears to tales of Amazons which seemed to realize the classic legends of antiquity, to stories of Patagonian giants, to flaming pictures of an El Dorado, where the sands sparkled with gems, and golden pebbles as large as birds' eggs were dragged in nets out of the rivers. [Footnote 2: The Venetian ambassador, Andrea Navagiero, who travelled through Spain in 1525, near the period of the commencement of our narrative, notices the general fever of emigration. Seville, in particular, the great port of embarkation, was so stripped of its inhabitants, he says, "that the city was left almost to the women." Viaggio fatto in Spagna, (Vinegia, 1563.) fol. 15.]
