Even more momentous was the new knowledge the age brought of the physical world. The brilliant conjectures of Copernicus paved the way for Galileo, and the warped and narrow cosmology which conceived the earth as the centre of the universe, suffered a blow that in shaking it shook also religion. And while the conjectures of the men of science were adding regions undreamt of to the physical universe, the discoverers were enlarging the territories of the earth itself. The Portuguese, with the aid of sailors trained in the great Mediterranean ports of Genoa and Venice, pushed the track of exploration down the western coast of Africa; the Cape was circumnavigated by Vasco da Gama, and India reached for the first time by Western men by way of the sea. Columbus reached Trinidad and discovered the "New" World; his successors pushed past him and touched the Continent. Spanish colonies grew up along the coasts of North and Central America and in Peru, and the Portuguese reached Brazil. Cabot and the English voyagers reached Newfoundland and Labrador; the French made their way up the St. Lawrence. The discovery of the gold mines brought new and unimagined possibilities of wealth to the Old World, while the imagination of Europe, bounded since the beginning of recorded time by the Western ocean, and with the Mediterranean as its centre, shot out to the romance and mystery of untried seas. It is difficult for us in these later days to conceive the profound and stirring influence of such an alteration on thought and literature. To the men at the end of the fifteenth century scarcely a year but brought another bit of received and recognized thinking to the scrap-heap; scarcely a year but some new discovery found itself surpassed and in its turn discarded, or lessened in significance by something still more new. Columbus sailed westward to find a new sea route, and as he imagined, a more expeditious one to "the Indies"; the name West Indies still survives to show the theory on which the early discoverers worked. The rapidity with which knowledge widened can be gathered by a comparison of the maps of the day. In the earlier of them the mythical Brazil, a relic perhaps of the lost Atlantis, lay a regularly and mystically blue island off the west coast of Ireland; then the Azores were discovered and the name fastened on to one of the islands of that archipelago. Then Amerigo reached South America and the name became finally fixed to the country that we know. There is nothing nowadays that can give us a parallel to the stirring and exaltation of the imagination which intoxicated the men of the Renaissance, and gave a new birth to thought and art. The great scientific discoveries of the nineteenth century came to men more prepared for the shock of new surprises, and they carried evidence less tangible and indisputable to the senses. Perhaps if the strivings of science should succeed in proving as evident and comprehensible the
