When and how were the first nautical charts constructed ? The earliest existent chart is the Carta Pisana (1275-1280). But researchers suspect a long tradition before that, and we know nothing about its development. Also, how were they updated with new geographical information ? These issues are particularly relevant for the medieval ones, but similar questions could be asked for the more recent, so-called, latitude charts of the Atlantic, which were developed by the Portuguese following the introduction of astronomical navigation. Where did the knowledge come from so to create these old maps remains a significant mystery.
