Фра Мауро
The original world map was made by Fra Mauro and his assistant Andrea Bianco, a sailor-cartographer, under a commission by king Afonso V of Portugal. The map was completed on April 24, 1459, and sent to Portugal, but did not survive to the present day. Fra Mauro died the next year while he was making a copy of the map for the Seignory of Venice, and the copy was completed by Andrea Bianco.
