[4] Christopher Columbus was a native of Genoa, Italy, where he was born about 1436. He was the son of a wool comber. At fourteen he began a seafaring life, and between voyages made charts and globes. About 1470 he wandered to Portugal, went on one or two voyages down the African coast, and on another (1477) went as far north as Iceland. Meantime (1473) he married a Portuguese woman and made his home at the Madeira Islands; and it was while living there that he formed the plan of finding a new route to the far East. [5] In 1271 Marco Polo, then a lad of seventeen, was taken by his father and uncle from Venice to the coast of Persia, and thence overland to northwestern China, to a city where Kublai Khan held his court. They were well received, and Marco spent many years making journeys in the khan's service. In 1292 they were sent to escort a royal bride for the khan from Peking (in China) to Tabriz, a city in Persia. They sailed from China in 1292, reached the Persian coast in 1294, and arrived safely at Tabriz, whence they returned to Venice in 1295. In 1298 Marco was captured in a war with Genoa, and spent about a year in prison. While thus confined he prepared an account of his travels, one of the most famous books of the Middle Ages. He described China (or Cathay, as it was then called), with its great cities teeming with people, its manufactures, and its wealth, told of Tibet and Burma, the Indian Archipelago with its spice islands, of Java and Sumatra, of Hindustan,--all from personal knowledge. From hearsay he told of Japan. In the course of the next seventy-five years other travelers found their way to Cathay and wrote about it. Thus before 1400 Europe had learned of a great ocean to the east of Cathay, and of a wonderful island kingdom, Cipan'go (Japan), which lay off its coast. All this deeply interested Columbus, and his copy of Marco Polo may still be seen with its margins full of annotations. [6] These sovereigns were just then engaged in the final struggle for the expulsion of the Moors from Spain, so they referred the appeal to the queen's confessor, who laid it before a body of learned men. This council of Salamanca made sport of the idea, and tried to prove that Columbus was wrong. If the world were round, they said, people on the other side must walk with their heads down, which was absurd. And if a ship should sail to the undermost part, how could it come back? Could a ship sail up hill?
