Every day the boys of Genoa, as they played along the wharves, could see the ships from different countries and could hear the stories of adventure told by the sailors. No wonder Christopher found it hard to work at his father's trade of combing wool; he liked to hear stories of the sea and to make maps and to study geography far better than he liked to comb wool or study arithmetic or grammar. He was eager to go to sea and while but a boy he made his first voyage. He often sailed with a kinsman, who was an old sea captain. These trips were full of danger, not only from storms but from sea robbers, with whom the sailors often had hard fights. [Sidenote: =Prince Henry's work=] While Columbus was growing to be a man, the wise and noble Prince Henry of Portugal was sending his sailors to brave the unknown dangers of the western coast of Africa to find a new way to India. The Turks, by capturing Constantinople, had destroyed Genoa's overland trade routes. [Illustration: THE BOY COLUMBUS _After the statue by Giulio Montverde in the Museum of Fine Arts, Boston_] [Sidenote: =Columbus goes to Lisbon=] The bold deeds of Henry's sailors drew many seamen to Lisbon, the capital of Portugal. Columbus went, too, where he was made welcome by his brother and other friends. Here he soon earned enough by making maps to send money home to aid his parents, who were very poor. [Illustration: A SEA FIGHT BETWEEN GENOESE AND TURKS _The Genoese were great seamen and traders. When the Turks tried to ruin their trade with the Far East by destroying their routes many fierce sea fights took place_] [Sidenote: =Sailors hope to reach India=] Columbus was now a large, fine-looking young man with ruddy face and bright eyes, so that he soon won the heart and the hand of a beautiful lady, the daughter of one of Prince Henry's old seamen. Columbus was in the midst of exciting scenes. Lisbon was full of learned men, and of sailors longing to go on voyages. Year after year new voyages were made in the hope of reaching India, but after many trials, the sailors of Portugal had explored only halfway down the African coast. [Sidenote: =Columbus' new idea=] It is said that one day while looking over his father-in-law's maps, Columbus was startled by the idea of reaching India by sailing directly west. He thought that this could be done, because he believed the world to be round, although all people, except the most educated, then thought the world flat. Columbus also believed that the world was much smaller than it really is. [Illustration: THE HOME OF COLUMBUS, GENOA] The best map of that time located India, China, and Japan about where America is. For once, a mistake in geography turned out well. Columbus, believing his route to be the shortest, spent several years in gathering proof that India was directly west. He went on long voyages and talked with many old sailors about the signs of land to the westward. [Sidenote: =A tricky king=]
