    The idea of sailing west to reach the riches of the East Indies and the Asian mainland was much in fashion with cultured Europeans during the late fifteenth century. Learned people agreed that the earth was round: their only questions were how long and how dangerous would be a trip to reach the Orient. Christopher Columbus, the son of an unknown weaver, and himself a weaver of ambitious dreams, made his historic voyage to the New World in 1492. He didn't go to school very much, but be learned to read and write Spanish during his travels. He also taught himself Latin because all the geography books were written in Latin. Sailing with a tiny fleet of three ships, the Santa Maria and two smaller ships, the Pinta and the Nina and a crew of ninety sailors, be found the thirty-three-day crossing easier than his nearly-decade-long effort to find royal sponsors willing to support it. The trip drew not only on his own skills as an expert ship's captain, but also on his ability to plan such an expedition, obtain governmental approval and financing, and finally, demonstrate its success so that such explorations could continue. He tried for years to get King Ferdinand and Queen Isabella to supply him with ships and money. Finally they agreed, but he made more demands. He wanted to be made a knight, admiral of the Ocean Sea. He wanted to be the viceroy(总督)and governor general of all lands he would discover. Also he wanted one-tenth of everything he found of value in the new lands. The explorations that followed Columbus-those of Cabot, Verrazano, Cartier, and many others-benefited from a new maritime technology borrowed from Arab sailors and from a variety of new vessels (船，舰) such as the light-weight caravels employed by Columbus. Sailors also perfected sails and various types of riggings that gave ships added stability and greater maneuverability(可操作性)on the open seas. And when leaving sight of the coast, new navigational aids-charts, compasses, and astrolabes-permitted them to determine their position with some, though not perfect, accuracy. Columbus himself made a total of four voyages to the New World but he did not become rich as he had hoped. At the end of his life he only had a pension the king and queen had given him because he was the first to reach the New World. He spent the last few months of his life in bed because of the pain of arthritis(关). Columbus not only discovered a New World, but led the way for other explorers.
