In the World Map of Fra Mauro, the most important and complete of the Middle Ages realized in Venice by the monk Camaldolese around 1450 AD, the Siwa Oasis appears in the right position with its monumental buildings and the lake with the name of Santariya but corrupt in Italian in "Seteria"
Fra Mauro (c.1400-1464) 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.
