But he did not spend a long time at his studies, for at the age of fourteen he went to sea. What he had learned, however, gave him an excellent groundwork, and from this time forward he made use of every opportunity to inform himself and to become a scholarly man. His first voyage was made with a distant relative, who was an adventurous and daring man, and who was ever ready to fight with any one with whom he could pick a quarrel. In course of time Columbus commanded a ship of his own, and became known as a bold and daring navigator. He made a voyage along the coast of Africa as far south as Guinea, and afterwards sailed northward to Iceland. At an early day he became familiar with the wildest kind of adventure, for at this time sea life on the Mediterranean was little more than a series of fights with pirates. Some say that during one of these conflicts Columbus's ship caught fire. In order to save his life, he jumped into the water and swam six miles to shore, reaching the coast of Portugal. Others say that he was attracted to that country by the great school of navigation which Prince Henry had established. However that may be, he appeared at Lisbon at the age of thirty-five, filled with the idea of sailing westward to reach those rich Eastern countries in which every one was so much interested. He was laughed at for expressing such an idea. It is not pleasant to be laughed at, but Columbus was courageous and never wavered in his belief. "The earth is a sphere," he said; "those foolish stories of its being flat and supported on a turtle's back cannot be true." But those persons to whom he talked only laughed the more. "Is there anything more foolish," they asked, "than to believe that there are people who walk with their heels up and with their heads hanging down?" "Think of a place where the trees grow with their branches down, and where it snows, hails, and rains upward!" Everybody thought him an idle dreamer. Columbus tried to persuade King John to furnish him with ships and allow him to test his belief. But King John cruelly deceived Columbus; for, after obtaining his maps and charts, he sent off an expedition of his own. He hoped in this way to gain the glory of the discovery. The sailors whom he sent, however, were not brave enough to continue the voyage, and returned, frightened by a severe storm. Columbus was so disgusted by the treachery of King John that he made up his mind to leave Portugal and go to Spain. So, taking his little son, Diego, with him, he started on his journey. He traveled from place to place, trying to find some person who would help him make his ideas known to King Ferdinand and Queen Isabella. He thought that if he could talk with them he could persuade them to furnish him with ships. [Illustration: Convent of La Rabida.]
