The most important manuscript map surviving from the early Age of Discovery, the Cantino World Map is named for Alberto Cantino, an Italian diplomatic agent in Lisbon who obtained it in 1502 for the Duke of Ferrara. It was covertly copied without authorization.  It incorporates extensive new geographical information based on four series of voyages: Columbus to the Caribbean, Pedro Álvarez Cabral to Brazil, Vasco de Gama followed by Cabral to eastern Africa and India, and the brothers Corte-Real to Greenland and Newfoundland. Except for Columbus, all had sailed under the Portuguese flag.
