The early fancies of isles in the western sea loomed up before his eyes, and repeated themselves in his dreams. These visions were heightened by that vague sense of wonder that is linked with the unknown. No wonder, then, that Columbus, with a bent almost preternatural toward the undiscovered regions of the globe, should dream of new lands, new men, new scenery, and new wealth. But to his vivid imagination dreams became realities, until he believed with all the force of his ardent nature that he was divinely commissioned to be a discoverer. Hitherto the Portuguese voyages familiar to Columbus had only skirted the coast of Africa, and discovered the Cape Verde Islands and the Azores. It was not till 1486, years after the idea of his western voyage took firm root in his mind, that the Cape of Good Hope was at last doubled by Vasco da Gama. All voyages prior to his had been only tentative and brief, slowly creeping from headland to headland, or else finding new islands by being drifted out of courses long familiar to mariners. It was the supreme merit of Columbus that he was the first to cut loose from one continent to find another, and to steer boldly across an unknown sea, in search of an unknown world. We need not belittle (still less need we deny) the finding of Greenland and of other parts of North America by the Norsemen in the ninth and tenth centuries. We may hail Eric the Red and his stout son, Leif Ericson, as pioneers in what may be termed coasting voyages of discovery. But the story of America gains as little from these shadowy and abortive voyages as civilization has gained from their fruitless results.
