Fra Mauro, O.S.B. Cam., was an Italian cartographer who lived in the Republic of Venice. He created the most detailed and accurate map of the world up until that time, the Fra Mauro map.
Mauro was a monk of the Camaldolese Monastery of St. Michael, located on the island of Murano in the Venetian Lagoon. It was there that he maintained a cartography workshop. He also was employed by some very powerful men like Prince Henry the Navigator.
