With all these opinions Columbus was familiar, for the list of his library and the annotations still preserved in his own handwriting, show that he was not an ignorant sailor, nor yet a wild visionary, but prepared by closest study for the task to which he gave his later years. His earlier career, on the other hand, had supplied him with abundant practical knowledge. Born in Genoa, a mother city of great seamen, probably in the year 1436, he had received a fair education in Latin, geography, astronomy, drafting, and other subjects useful to the master-mariner of those days. He had sailed the Mediterranean, and prior to his great adventure, had been as far north as Iceland, and on many voyages down the African coast. Following his brother Bartholomew, who was a map-maker in the Portuguese service, he came about 1470 to Lisbon, even then a center of geographical knowledge and maritime activity. Probably as early as this time the idea of a western voyage was in his mind.
Skepticism may account for Portugal's failure to listen to his proposals; and her interest was already centered in the route around Africa under her exclusive control. The tale of his years of search for assistance is well known. Indeed, while the fame of Columbus rests rightly enough upon his discovery of a new world, of whose existence he had never dreamed and which he never admitted in his lifetime, his greatness is best shown by his faith in his vision, and the steadfast energy and fortitude with which he pushed towards its practical accomplishment, during years of vain supplication, and amid the trials of the voyage itself. He had actually left Granada, when Isabella of Spain at last agreed to support his venture. In the contract later drawn up he drove a good bargain, contingent always upon success; he was to be admiral and viceroy of islands and continents discovered and their surrounding waters, with control of trading privileges and a tenth part of the wealth of all kinds derived.
With the explorations of Columbus on his first and his three later voyages (in 1496, 1498, and 1502) we are less concerned than with the first voyage itself as an illustration of the problems and dangers faced by the navigator of the time, and with the effect of the discovery of the new world upon Spain's rise as a sea power. The three caravels in which he sailed were typical craft of the period. The _Santa Maria_, the largest, was like the other two, a single-decked, lateen-rigged, three-masted vessel, with a length of about 90 feet, beam of about 20 feet, and a maximum speed of perhaps 6-1/2 knots. She was of 100 tons burden and carried 52 men. The _Pinta_ was somewhat smaller. The _Niña_ (Baby) was a tiny, half-decked vessel of 40 tons. Heavily timbered and seaworthy enough, the three caravels were short provisioned and manned in part from the rakings of the Palos jail.
