Jia Hui (Christopher Columbus)

Christopher Columbus was born in Genoa, Italy in 1451. His father was Domenico Colombo who worked as a wool weaver His mother was Susanna Fontanarossa. He had three brothers, Bartolomeo, Giovanni Pelligrino and Giacomo.Although how much formal education Columbus received as a child is not known, the schools of Italian craft guilds (which Columbus, as the son of a wool weaver, would have attended) did offer a rudimentary level of reading and writing. As a boy, Christopher joined his father in the family business of wool processing and selling. He may have worked as a clerk in a Genoese bookshop as well. However, as did many other young men who grew up in a major seaport, Columbus soon began a life of seafaring. Beginning his seagoing career at age 14, Columbus served on various ships in various roles, including messenger, common sailor, and, perhaps, even as a 21-year-old privateer. Columbus son Ferdinand stated in History of the Life and Deeds of Christopher Columbus that in 1472 Columbus was given command of a ship on a privateering expedition to Tunis in northern Africa. In a lost letter, Columbus supposedly related to his son how Ren?I, duke of the French province of Anjou, had commissioned Columbus to make a surprise attack on a large Spanish ship sailing off the coast of North Africa. Most historians doubt, however, that Columbus ever received command of the expedition. Much more credible, though, is a subsequent expedition. In 1474 Columbus was hired as a sailor on a ship bound for the island of in the Aegean Sea, an arm of the eastern Mediterranean Sea. This was his first long voyage and must have proved profitable, because after spending a year on the island he was able to become economically independent from his family. This voyage also represents a great irony in the life of Columbus the trip to this small island in the Aegean brought him the closest he would ever get to Asia. On August 13, 1476, a Genoese commercial expedition of five ships bound for England gave Columbus his first opportunity to leave the Mediterranean Sea and sail into the Atlantic Ocean. But it was an inauspicious beginning for Columbus: According to tradition, the entire fleet was attacked by French privateers off Cape Saint Vincent on the southwestern tip of Portugal. Both sides lost ships; Columbus, one of the unfortunate ones whose ship was burned, had no escape other than to swim for the Portuguese coast. He made it to shore by clinging to wreckage. After regaining his strength in the port of Lagos, Columbus made his way to Lisbon and its large community of Genoese merchants and shipbuilders. He was 25 years old. Columbus settled in Lisbon. Lisbon had become a haven for explorers, adventurers, entrepreneurs, merchants, and any others who saw their fortunes tied to the trade winds and ocean currents. Columbus 's brother Bartholomew worked in Lisbon as a mapmaker, and for a time the brothers worked together as draftsmen and book collectors. Later that year, Columbus set sail on a convoy loaded with goods to be sold in northern Atlantic ports. Columbus met and married Felipa Perestrello e Moniz, the daughter of a respected, though relatively poor, noble family. Felipa 's father, Bartolomeo Perestrello, who was already deceased when Columbus met Felipa, had served as governor of Porto Santo in the Madeira Islands, a Portuguese possession off the northwest coast of Africa. Soon after their marriage, the newlyweds accompanied the rest of the family back to Porto Santo, where Felipa 's oldest brother took over the governorship. Columbus and Felipa moved to the larger island of Madeira , soon after their son Diego was born. It is believed that Felipa died soon after. Columbus sailed to the Portuguese fortress of Elmina, in what is now Ghana, on the western coast of Africa. Columbus was impressed with the riches Africa offered, especially gold. In addition, like all good navigators, he was eager to learn about winds and ocean currents from the local pilots and sailors. In the waters off the coast of Africa and the nearby Canary Islands, Columbus first observed the ocean phenomenon known as the Canaries Current . Knowledge of this fast-moving current running west of the Canary Islands could well have been the reason that Columbus later chose to start his crossing of the Atlantic in the latitude of the Canaries, far south of Spain or Portugal. The experiences of these years led directly to the genesis of Columbus 's plan to reach the east by going west, what he called his interprise of the Indies.To Europeans in Columbus 's day, all lands to the east of the Indus River in Asia were the Indies. Inspiration and assistance for his plan came from a number of sources. First, his marriage into the Portuguese nobility proved helpful because, although relatively poor, the family still had connections to the Portuguese court. Columbus apparently gained access to his father-in-law 's papers and found a wealth of information, including maps, charts revealing ocean currents, interviews with sailors, and stories about objects that had drifted to the coast of the Madeira Islands from the west. Also contributing to the formation of Columbus 's plan were his association with the Genoese community in Portugal and his expeditions to Africa. Both furthered his knowledge of Atlantic waters, and his trips to Africa brought him close to the Canary Islands, giving him knowledge of the Canaries Current. Also, while in ports in England, Ireland, Iceland, and other northern regions, Columbus may have heard stories of lands to the west of Iceland. Although the histories of the Vikings, who settled Iceland and Greenland , they never became part of the knowledge base of medieval Europeans, it is believed that stories of their encounters with unknown islands in the northern Atlantic were widespread. Columbus 's genius was his remarkable ability to gather information from around the Mediterranean and the Atlantic and combine his own experiences with ancient theories from books in a way that few navigators could. Columbus 's idea of sailing west to get to the east was not original with him, nor did he ever claim that it was. Columbus drew upon science and knowledge accumulated over thousands of years. In Greek and Roman times, for example, geographers theorized that there was only one body of water on the surface of the Earth and that it connected Europe and Asia. If so, one could theoretically sail from the west to get to the east. Only the distance was disputed. Columbus 's ideas of the size of the earth and the distance between Europe and Asia were based on the descriptions contained in several geographic works. These works included the 2nd-century manuscript Geography by Ptolemy; Imago Mundi (Image of the World) by Pierre dilly, published in the early 1480s; and The Travels of Marco Polo, written in 1298 after Marco Polo returned from China. Unfortunately, his ideas did not prove particularly accurate. Columbus founded his theory on two mistaken propositions that the Asian continent stretched much farther to the east than it actually does, and that Japan lay about 2,400 km (about 1,500 mi) east of the Asian mainland. Columbus also greatly underestimated the circumference of the earth. Columbus calculated that the Canary Islands lay only about 4,440 km (about 2,760 mi) from Japan; the actual distance is about 19,000 km (about 12,000 mi). Similar errors were made by other learned men of the time, including the Florentine geographer Paulo de Pozzo Toscanelli, with whom Columbus may have corresponded. Neither Columbus nor anyone else in Europe suspected that two vast continents lay in the way of a westward passage to Asia. Columbus decided to seek patronage for his plan first in Portugal. With few interruptions, the Portuguese crown had encouraged and supported exploration for over a century, and nearly all new discoveries in the Atlantic were Portuguese. Furthermore, it was well known that the reigning monarch, King John II, was personally committed to sailing around Africa and discovering a direct sea route to the Indian Ocean and Asia. The king 's strong support of geographical exploration made him a logical choice for Columbus to approach. In addition, Columbus had been in Portugal for seven years and had married a Portuguese noblewoman. According to tradition, in 1484 the king listened to Columbus 's proposal to sail to the east by going west and summarily passed it on to his Council of Geographical Affairs. But after a public hearing, the council denied the request on the grounds that it was too expensive, that Columbus was wrong about distances and measurements, and that such a plan contradicted Portugal 's commitment to finding an eastward route to Asia by traveling around Africa.
