The enigma of the origin of portolan charts : a geodetic analysis of the hypothesis of a Medieval origin

by Roel Nicolai

Using geodetic and statistical techniques, this study analyses the origins and construction of medieval portolan charts. It reveals their unexpected accuracy and alignment with the Mercator projection, challenging the belief that they were created by medieval mariners.

brief_description
The sudden appearance of portolan charts, realistic nautical charts of the Mediterranean and Black Sea, at the end of the thirteenth century is one of the most significant occurrences in the history of cartography. Using geodetic and statistical analysis techniques these charts are shown to be mosaics of partial charts that are considerably more accurate than has been assumed. -- Trove
