Among those for whom the voyage of Diaz was of vital importance was an unknown Italian map-maker, already possessed with the one idea that was to make him more famous than Diaz, but which as yet had brought him only poverty and humiliation. Christopher Columbus, son of a Genoese wool-comber, sailor and trader and student of men and of maps from the age of fourteen, had come, about the year 1477, from London to Lisbon, where he married in 1478 Felipe Moniz de Perestrello, whose father had been a captain in the service of Prince Henry and first governor of Porto Santo. Student of cartography and professional map-maker, expert sailor himself, who had probably been to the Gold Coast, associating with captains and sailors in this seaport town of Lisbon, Columbus must have picked up all the common sailors' gossip of the age, and all the best-known scientific speculation. With the Greek tradition that the Indies might be reached by sailing west from the Pillars of Hercules, he was probably familiar, even if he had not read the famous statement of Aristotle in Roger Bacon's _Opus Majus_, or in the _Imago Mundi_ of Pierre d'Ailly; familiar also he certainly was with the persistent mediaeval legends of islands in the western Atlantic,--Atlantis, and the Seven Cities, and Isles of St. Brandan. Here in Lisbon, poring over old maps, by fortunate miscalculation underestimating the size of the earth, noting, as expedition after expedition returned, the indefinite southern extension of the African coast, Columbus became convinced that the Portuguese had chosen the longer route to the East, and that "the Indies in the east might in the Earth's Globositie be as readily found out by the west, following the sun in his daily journey." To reach the Indies by sailing west, and to discover, for the king who should authorize him, such new lands as might fall his way, became henceforth the consuming ambition of his life. It was a project which he had already, about 1484, laid before the King of Portugal. Repulsed, and at the same time betrayed, he went to Spain, where he was encouraged by the Count Medina Celi and the Cardinal Mendoza, only to have his plan rejected by the Council to which it was referred. The queen was not unfavorably disposed, but the Moorish wars occupied her days and depleted her treasury. Weary with following the court about, it must have been with profound discouragement that Columbus heard of the success of Diaz in 1488. For the time was short; Diaz had all but reached the goal, and one more voyage might bring the Portuguese to India before Columbus could induce the Spanish sovereigns to try the better plan.
