Summary

  • Columbus had, perhaps, more influence on mankind than any individual since Muhammad. Despite his humble origins, he rose by dint of spectacular achievements to fame and fortune; he was hailed in his lifetime as a prophet and ‘a new apostle’. Yet he died in the misery of embittered frustration.

  • The reader of these pages will probably be happy to have avoided Columbus in the flesh. His tireless self-recommendation must have been wearying to others. His egotism approached the obsessive and his self-righteousness, the paranoid. He was loquacious rather than eloquent and he gives the impression of having wearied enemies into opposition and bored friends into assent.

  • The most consistent single purpose to which Columbus’s life was dedicated was the desire to found a great noble dynasty of his own: the priorities he claimed- the service of God and of the Monarchs of Spain, the advancement of science- appear, by comparison, a subordinate or ancillary.

Christopher Columbus

  • Name: Cristoforo Columbo (Italy), Admiral Don Cristobal Colon (Portugal), Christopher Columbus (Spain).

  • Early Life:

    • 1451: Columbus is born in Genoa, Italy.

    • 1476: Columbus moves to Lisbon, Portugal, after surviving a shipwreck off Cape Saint Vincent. In Portugal, His way of life involved sugar buying trips to islands of the Atlantic- certainly Madeira and Porto Santo and presumably to the Azores and the Canaries.

      • 1478: A young Columbus trades sugar in Madeira for Genoese businessmen. 

      • 1478-1480: Marriage of Columbus to Dona Felip Moniz.

      • 1482-1485: Columbus trades along the coast of W. Africa.

      • 1484: Columbus begins seeking support for an attempt to reach Asia by sailing westwards. King John II of Portugal rejects his requests for ships and men. It was Columbus’s egregious demands that deterred the Portuguese from supporting him.

      • 1485: Columbus moves to Spain.

  • Navigation

    • Relative or very approximate latitude- sufficient for practical, if not for scientific, purposes- could be gauged by judging the height of the sun at noon or the Pole Star at evening with the naked eye.

    • Columbus’s preferred method was to time the hours of daylight and read the corresponding latitude from a published chart.

    • Columbus espoused an estimate for the length of a degree, and therefore the size of the globe, which was too small by about 25%, and about 8% smaller than that of the most favorable estimate at the time.

    • “I have found that my measurements endorse the opinion of Alfraganus: that is, that to any one degree, 56 and 2/3 miles correspond. Therefore, his estimate can be relied on. Therefore, we may say that the perimeter of the Earth at the equator is 20,400 miles.”-Columbus.

  • Personality

    • He shared prejudices common in his day, regarding Judaism as a source of heretical depravity, and was inclined to suspect his opponents of the taint of Jewish provenance.

    • Egregious social ambition was one of the great driving forces of his life.

    • Wishful thinking was one of Columbus’s most consistent mental characteristics.

    • Columbus seems to have come to regard himself as an almost messianic figure.

    • Three aspects of his character seem to have drawn him towards this rather egotistical cosmology: his habit of turning to God in adversity; a mental condition approaching paranoia; and a tendency to crack under strain.

    • The learned sources to which he had access; the Imago Mundi of Pierre d’Ailly, Ptolemy’s Geography, and the Historia Rerum of Pius II.

  • “My signature which it is my present custom to use, which is an .X with an .S above it and an .M with a Roman .A above it and above that an .S and after it a .Y with an .S above.”

First Voyage

  • Motivations: The gold of Marco Polo’s reputed Island of Cipangu (most prominent), evangelization of the native populations, extension of the territories of Spain, social ambition for his family, service to God, and the reconquest of Jerusalem (as a necessary precondition to the Last World Emperor and the cosmic struggle of that hero with the Antichrist that, according to Joachim of Fiore, preceded the last days).

  • Ships

    • Nina: Supplied by the Pinzon family and commanded by Vicente Yanez.

    • Pinta: Supplied by the Pinzon family and commanded by Martin Alonso Pinzon.

    • Santa Maria: Supplied and commanded by Juan de la Cosa?

  • Navigation

    • The Atlantic could only be crossed with the aid of prevailing winds; these could be picked up in the Canaries but not much further S. or N.

    • Columbus kept two logs: a false one showing the shorter distances and a true one the longer.

    • The estimated speed was compared with the passage of time, reckoned from sand-clocks turned at half hour intervals by ships boys; a boy’s negligence or excessive zeal or eagerness to speed the change of watch could all throw the calculations seriously awry. At a typical juncture of his first ocean crossing, Columbus’s pilots differed by a margin of 10% in their estimates of distance traversed. Columbus’ estimates on distance were subject to an error commonly of ~100%.

  • Discoveries

    • Guanahani: Named San Salvador by Columbus; small, flat, fertile, and dotted with pools. It was largely protected by a reef, with what Columbus calls a lagoon in the middle.

    • Cuba: Columbus seems to have realized almost at once that Cuba was not Cipangu, as he had hoped during his approach: thereafter, references to Cipangu cease, and those to Cathay multiply.

    • Central Antilles: Visited by Columbus and populated by the Arawak peoples- the Taino and Ciguayo.

    • Villa de Navidad: A “great town” named by Columbus on Hispaniola.

  • Misc

    • Columbus suffered the loneliness of command; he was a member of none of the almost ethnic groups of which his crews were composed- the Basques, for instance, who rioted together, or the men of Palos and Moguer, who were friends of the employees of Pinzon. He suffered unremitting fear of mutiny of perfidy.

    • His first religious experience occurred on his way home from his first voyage, and the conviction that he was an agent of providence grew on him from then onwards.

Second Voyage

  • Motivations

    • Columbus had no difficulty in obtaining a commission to return to his discovery to establish a colony, initiate trade and extend exploration. He was further commanded to produce a map that could be used for negotiations with Portugal on the division of the spoils of the exploration.

  • Discoveries

    • The Indians, whom he had extolled as peaceful and labeled as biddable, had risen up and massacred the garrison he had left behind.

  • Misc

    • One by one, Columbus’s earlier false predictions- about the gold, the climate, the Indians- are stripped away and the horrible reality of life on a savage frontier is exposed.

 

Misc Quotes (2nd Voyage)

“Grant a license and permits for sufficient numbers of caravels to come here every year and bring the said cattle and other provisions and the things needed to settle the country and exploit the soil- and to do so at reasonable prices and at the carrier’s expense. The good could be paid for with salves, drawn from among the cannibals.”-Columbus (1494).

Third Voyage

 

Misc Quotes (3rd Voyage)

“Maize, which is a kind of grain which grows in spiky cob resembling a spindle.”-Columbus (1498).

“I find that the sea is full of a weed of a kind that resembles pine branches very heavily laden with a growth like that of the mastic plant. And so thick is it that on my first voyage I thought it was a shoal.”-Columbus (1498).

“The result is that I have had more trouble from the Christians than the Indians, am still not at the end of it.”-Columbus (1498).

“I should be their viceroy and Governor in those lands. I should have the tenth part of whatever should be found or had or yielded by way of profit similar the 8th part of the lands.”-Columbus (1498).

“I concluded that the globe is not round in the way they say, but is of the same shape as a pear, which may be very round all over but not in the part where the stalk is, which sticks up; or it is as if someone had a very round ball, and at one point on its surface it was as if a woman’s nipple had been put there; and this teat-like part would be the most prominent and nearest to the sky; an it would be on the equator…And so from all the foregoing it appears that the very mild climate which is to be found there is a result of behing higher up in the world, closer to the refined atmosphere which I am describing.”-Columbus (1498).

“Holy scriptures bear witness that or Lord made the earthly paradise and placed there the tree of life and that from it flows a fountain from which issues the four chief rivers of this world: the Ganges in India, the Tigris and Euphrates in…which divide the mountains and create the land of Mesopotamia and flows into Persia, and the Nile, which rises in Ethiopia and joins the sea at Alexandria.”-Columbus (1498).

“I have come to believe that this land is an enormous continent, of which until not nothing has been known.”-Columbus (13 Aug, 1498).

May it please god to free me of them (of the pains in his eyes), for he well knows that I do not endure these hardships to gather treasure nor find riches for myself, for, to be sure, I know that all is vanity that is accomplished in this world, save what is to the honor and service fo God, which is not to build up riches or causes of pride or many of the other things we use in this world to which we are better affected than to the things that can save our souls.”-Columbus (1498).

Fourth Voyage

  • Motivations

  • Discoveries

    • Columbus made at least a tentative identification in his mind of the strait of Malacca, through which Marco Polo had traveled at the foot of the Golden Chersonese (Malay Peninsula).

  • Misc

    • The most disturbing feature of Columbus’s mental state at this time was that he sought to circumvent the fact of his failure by senselessly affirming that he had succeeded.

 

Misc Quotes (4th Voyage)

“Was there ever a man born- not excepting Job himself- who would not die of despair at being denied refuge, at the hazard of his life and soul and those of his son and brothers and companions, in the very land and harbours which, by God’s will and sweating blood, I won for Spain?”-Columbus (1503).

“For, to my sorrow, the 20y of service I have rendered, with so much hardship and danger, have done me so little good that today in Castile I do not possess so much as a tile for my roof. If I want to eat or sleep I have nowhere to go save the inn or the tavern, and more often than not I am without the price of a shirt.”-Columbus (1503).

“This world is small. Land covers six parts of it and only the seventh is covered by water. I say the world is not as big as commonly supposed and that one degree measured along the Earth’s surface at the equator corresponds to 56 and 2/3 miles, as sure as I stand here.”-Columbus (1503).

“For it is certain that if the things that have befallen here are examined, it could be said of them, ‘How much they resemble the experiences of the people of Israel!’-Columbus (1503).

People

  • Bartolomé de las Casas (1484-1566): Spanish explorer appointed as first resident bishop of Chiapas and the first officially appointed ‘Protector of the Indians’. His extensive writings describe the atrocities committed by the colonizers against the indigenous peoples.  

    • Las Casas was guided by two considerations above all. First, he was concerned to fulfill his role as protector of the Indians. He collected material designed to show the inhabitants of the New World in the best possible light, as possessing rational intellects, legitimate polities, natural rights, and inherent goodness. Second, he had a providential conception of history, according to which the discovery of the New World was ordained at a propitious moment for the salvation of the natives’ souls, and Columbus was divinely elected as the instrument of it.

  • Juan de la Cosa (1450-1510): Castilian navigator, cartographer, Explorer, and owner of the ‘Santa Maria’; made the first world map (mappa mundi) depicting the new discoveries of the Americas. De la Cosa died in an armed confrontation with indigenous locals while trying to gain possession of Urabá.

  • Jose Vizinho (XX-YY): Portuguese Jew and early scientists who translated tables of latitude based on the angle of the declination of the sun.

  • Paolo dal Pozzo Toscanelli (1397-1482): Italian scientists; among the first to create a map on a grid system.

  • Luis de Santangel (d. 1498): Treasurer of the Crown of Aragon; instrumental in putting together the consortium that advanced the money for the Columbus enterprise.

  • Amerigo Vespucci (1451-1512): Italian explorer and navigator; the namesake for ‘America’. After befriending Columbus, Vespucci published his claim to have been the first discover of the American continent, which he called “New World”. The claim inspired cartographer Martin Waldseemüller to recognize Vespucci’s accomplishments in 1507 by applying the Latinized form “America” on a map of the new world. Other cartographers followed suit.

  • Diego Mendez de Salcedo (1472-1536): Undertook one of the most daring adventurers of Columbus’ 4th expedition, canoeing from Jamaica to Hispaniola with a native oarsman, accompanied by a second canoe with a Genoese officer, Bartolomeo Fieschi. The canoes labored against the current; the fresh water gave out; the oarsmen began to die of third and Mendez fell sick. At least, after 5d toiling at the paddles, both canoes reached Hispaniola safely, though at a point far distant from Santo Domingo.

Misc Quotes

“People have come from Cathay by heading towards the East. We have seen a good deal of evidence of this, most particularly, in Galway in Ireland, a man and a woman in two wooden boats, carried off by a storm in marvelous fashion.”

“As one goes, one’s knowledge grows.”-Columbus.

“For a drop of water can wear a hole even in a stone.”-Columbus.

“All your afflictions are engraved in letters of marble and there is a purpose behind them all.”

“Though the king was in no hurry to satisfy Columbus- delay was the crowns’ constant resource in dealing with petitioners.”

“St. Augustine says that in the end of this world must come in the 7th millennium after its creation. From the creation of the world or of Adam until the advent of our Lord Jesus Christ, there elapsed 5343y and 318d. Adding to them 1501 which is not yet finished, makes in all 6844 rising 45. By this account, only 155y are wanting to complete 7000…A very great part of the prophecies and Holy Scriptures has now been fulfilled.”-Columbus.
