How the Map was drawn – the ingredients
The map was drawn between 1408 – 1410, before Portuguese caravels set sail, before the Azores were discovered, 80 years before the shape of Africa was known to Europeans.
It was in fact composed of :
i) Albertin de Virga’s map of the Mediterranean (1409)
and
ii) Zheng He’s 1408 Master Chart of the World.
