Florentines were one of the driving forces behind the Age of Discovery. Florentine bankers financed Henry the Navigator and the Portuguese explorers who pioneered the route around Africa to India and the Far East. It was a map drawn by the Florentine Paolo dal Pozzo Toscanelli, a student of Brunelleschi, that Christopher Columbus used to sell his "enterprise" to the Spanish monarchs, and which he used on his first voyage. Mercator's "Projection" is a refined version of Toscanelli's, taking the Americas into account.
