In the year 1486 Bartholomew Diaz, trying to find the land of Prester John by sea, had reached the southernmost point of Africa. At first he called it the Storm Cape, on account of the strong winds which had prevented him from continuing his voyage toward the east, but the Lisbon pilots who understood the importance of this discovery in their quest for the India water route, changed the name into that of the Cape of Good Hope.

One year later, Pedro de Covilham, provided with letters of credit on the house of Medici, started upon a similar mission by land. He crossed the Mediterranean and after leaving Egypt, he travelled southward. He reached Aden, and from there, travelling through the waters of the Persian Gulf which few white men had seen since the days of Alexander the Great, eighteen centuries before, he visited Goa and Calicut on the coast of India where he got a great deal of news about the island of the Moon (Madagascar) which was supposed to lie halfway between Africa and India. Then he returned, paid a secret visit to Mecca and to Medina, crossed the Red Sea once more and in the year 1490 he discovered the realm of Prester John, who was no one less than the Black Negus (or King) of Abyssinia, whose ancestors had adopted Christianity in the fourth century, seven hundred years before the Christian missionaries had found their way to Scandinavia.

These many voyages had convinced the Portuguese geographers and cartographers that while the voyage to the Indies by an eastern sea-route was possible, it was by no means easy. Then there arose a great debate. Some people wanted to continue the explorations east of the Cape of Good Hope. Others said, “No, we must sail west across the Atlantic and then we shall reach Cathay.”

Let us state right here that most intelligent people of that day were firmly convinced that the earth was not as flat as a pancake but was round. The Ptolemean system of the universe, invented and duly described by Claudius Ptolemy, the great Egyptian geographer, who had lived in the second century of our era, which had served the simple needs of the men of the Middle Ages, had long been discarded by the scientists of the Renaissance. They had accepted the doctrine of the Polish mathematician, Nicolaus Copernicus, whose studies had convinced him that the earth was one of a number of round planets which turned around the sun, a discovery which he did not venture to publish for thirty-six years (it was printed in 1543, the year of his death) from fear of the Holy Inquisition, a Papal court which had been established in the thirteenth century when the heresies of the Albigenses and the Waldenses in France and in Italy (very mild heresies of devoutly pious people who did not believe in private property and preferred to live in Christ-like poverty) had for a moment threatened the absolute power of the bishops of Rome. But the belief in the roundness of the earth was common among the nautical experts and, as I said, they were now debating the respective advantages of the eastern and the western routes.

Among the advocates of the western route was a Genoese mariner by the name of Cristoforo Colombo. He was the son of a wool merchant. He seems to have been a student at the University of Pavia where he specialised in mathematics and geometry. Then he took up his father’s trade but soon we find him in Chios in the eastern Mediterranean travelling on business. Thereafter we hear of voyages to England but whether he went north in search of wool or as the captain of a ship we do not know. In February of the year 1477, Colombo (if we are to believe his own words) visited Iceland, but very likely he only got as far as the Faröe Islands which are cold enough in February to be mistaken for Iceland by any one. Here Colombo met the descendants of those brave Norsemen who in the tenth century had settled in Greenland and who had visited America in the eleventh century, when Leif’s vessel had been blown to the coast of Vineland, or Labrador.
