Christopher Columbus
Early life

Columbus's early life is obscure, but scholars believe he was born in the Republic of Genoa between 25 August and 31 October 1451. His father was Domenico Colombo, a wool weaver who worked in Genoa and Savona, and owned a cheese stand at which young Christopher worked. His mother was Susanna Fontanarossa. He had three brothers— Bartholomew, Giovanni Pellegrino, and Giacomo (also called Diego) —as well as a sister, Bianchinetta. Bartholomew ran a cartography workshop in Lisbon for at least part of his adulthood.

His native language is presumed to have been a Genoese dialect (Ligurian) as his first language, though Columbus probably never wrote in it. His name in 15th-century Genoese was Cristoffa Corombo, in Italian, Cristoforo Colombo, and in Spanish Cristóbal Colón.

In one of his writings, he says he went to sea at 14. In 1470, the family moved to Savona, where Domenico took over a tavern. Some modern authors have argued that he was not from Genoa, but from the Aragon region of Spain or from Portugal. These competing hypotheses have been discounted by most scholars.

In 1473, Columbus began his apprenticeship as business agent for the wealthy Spinola, Centurione, and Di Negro families of Genoa. Later, he made a trip to the Greek island Chios in the Aegean Sea, then ruled by Genoa. In May 1476, he took part in an armed convoy sent by Genoa to carry valuable cargo to northern Europe. He probably visited Bristol, England, and Galway, Ireland, where he may have visited St. Nicholas' Collegiate Church. It has been speculated he went to Iceland in 1477, though many scholars doubt this. It is known that in the autumn of 1477, he sailed on a Portuguese ship from Galway to Lisbon, where he found his brother Bartholomew, and they continued trading for the Centurione family. Columbus based himself in Lisbon from 1477 to 1485. In 1478, the Centuriones sent Columbus on a sugar-buying trip to Madeira. He married Felipa Perestrello e Moniz, daughter of Bartolomeu Perestrello, a Portuguese nobleman of Lombard origin, who had been the donatary captain of Porto Santo.

In 1479 or 1480, Columbus's son Diego was born. Between 1482 and 1485, Columbus traded along the coasts of West Africa, reaching the Portuguese trading post of Elmina at the Guinea coast in present-day Ghana. Before 1484, Columbus returned to Porto Santo to find that his wife had died. He returned to Portugal to settle her estate and take Diego with him.

He left Portugal for Castile in 1485, where he took a mistress in 1487, a 20-year-old orphan named Beatriz Enríquez de Arana. It is likely that Beatriz met Columbus when he was in Córdoba, a gathering place for Genoese merchants and where the court of the Catholic Monarchs was located at intervals. Beatriz, unmarried at the time, gave birth to Columbus's second son, Fernando Columbus, in July 1488, named for the monarch of Aragon. Columbus recognized the boy as his offspring. Columbus entrusted his older, legitimate son Diego to take care of Beatriz and pay the pension set aside for her following his death, but Diego was negligent in his duties.

Columbus learned Latin, Portuguese, and Castilian. He read widely about astronomy, geography, and history, including the works of Ptolemy, Pierre d'Ailly 's Imago Mundi, the travels of Marco Polo and Sir John Mandeville, Pliny 's Natural History, and Pope Pius II 's Historia rerum ubique gestarum. According to historian Edmund Morgan,

Columbus was not a scholarly man. Yet he studied these books, made hundreds of marginal notations in them and came out with ideas about the world that were characteristically simple and strong and sometimes wrong...
