When did Columbus find america?

When Did Columbus 'Discover' The Americas? 1492? Not according to Ruggero Marino, who claims that Columbus actually reached America in 1485. The conventional view is that Columbus set sail on the first of his four great voyages in 1492, having been sponsored by Ferdinand II and Isabella I of Spain. Marino argues that there was an earlier, and wholly successful voyage, financed by Pope Innocent VIII and his relatives, the Medici family. Marino continues, claiming that when Innocent died the new Pope, Alexander VI, gave the 'rights' and information to the leaders of his native Spain, prompting Columbus's, apparently better known, journeys.
