Already in the early part of the fifteenth century Portuguese sea-captains had skirted the western coast of Africa, and by the close of the century others of their number had rounded the Cape of Good Hope, in their search for a water route to the Indies. But Spain, at that time the most powerful nation of Europe, adopted a plan quite different from that of the Portuguese. What this plan was and how it was carried out, we can best understand by an acquaintance with the life and work of the great sea-captain and navigator, Christopher Columbus. More than four hundred and fifty years ago there lived in the city of Genoa a poor workingman, who made his living by preparing wool for the spinners. Of his four sons, the eldest was Christopher, born in 1436. Young Christopher was not, so far as we know, very different from most other boys in Genoa. He doubtless joined in their every-day sports, going with them to see the many vessels that sailed in and out of that famous sea-port, and listening for hours to the stories of sailors about distant lands. But he did not spend all his time in playing and visiting the wharves, for we know that he learned his father's trade, and in school studied, among other things, reading, arithmetic, grammar, geography, and map-drawing. We can easily believe that he liked geography best of all, since it would carry his imagination far out over the sea and to lands beyond the sea. In map-drawing he acquired such skill that when he became a man he could earn his living, when occasion demanded, by making maps and charts. Beyond these facts little is known about the boyhood and youth of Columbus. Very likely much of his early life was spent upon the sea, sailing on the Mediterranean and along the west coast of Africa. Once he went as far north as England and perhaps even farther, but of this we are not certain. In the course of many voyages he heard much of the work done by Portuguese sailors and discoverers, for Portugal was at that time one of the greatest sea-powers of the world. As Lisbon, the capital of Portugal, was naturally a centre for sea-faring men, and as it was also the home of his brother Bartholomew, Columbus, at the age of about thirty-five, went there to live. [Illustration: Places of Interest in Connection with Columbus's Earlier Life.] Columbus was a man of commanding presence. He was large, tall, and dignified in bearing, with a ruddy complexion and piercing blue-gray eyes. By the time he was thirty his hair had become white, and fell in wavy locks about his shoulders. Although his life of hardship and poverty compelled him to be plain and simple in food and dress, he always had the air of a gentleman, and his manners were pleasing and courteous. But he had a strong will, which overcame difficulties that would have overwhelmed most men.
