recovered from their fright. But the voyages of da Gama and Magellan proved the practical possibilities of an eastern water-route to the Indies. Then the rulers of Genoa and Venice, the two great commercial centres of the Middle Ages and the Renaissance, began to be sorry that they had refused to listen to Columbus. But it was too late. Their Mediterranean became an inland sea. The overland trade to the Indies and China dwindled to insignificant proportions. The old days of Italian glory were gone. The Atlantic became the new centre of commerce and therefore the centre of civilisation. It has remained so ever since.
See how strangely civilisation has progressed since those early days, fifty centuries before, when the inhabitants of the Valley of the Nile began to keep a written record of history. From the river Nile, it went to Mesopotamia, the land between the rivers. Then came the turn of Crete and Greece and Rome. An inland sea became the centre of trade and the cities along the Mediterranean were the home of art and science and philosophy and learning. In the sixteenth century it moved westward once more and made the countries that border upon the Atlantic become the masters of the earth.
There are those who say that the world war and the suicide of the great European nations has greatly diminished the importance of the Atlantic Ocean. They expect to see civilisation cross the American continent and find a new home in the Pacific. But I doubt this.
The westward trip was accompanied by a steady increase in the size of ships and a broadening of the knowledge of the navigators. The flat-bottomed vessels of the Nile and the Euphrates were replaced by the sailing vessels of the Phœnicians, the Ægeans, the Greeks, the Carthaginians and the Romans. These in turn were discarded for the square-rigged vessels of the Portuguese and the Spaniards. And the latter were driven from the ocean by the full-rigged craft of the English and the Dutch.
At present, however, civilisation no longer depends upon
