The enigma of the origin of Portolan charts : : a geodetic analysis of the hypothesis of a medieval origin / / editor, Roel Nicolai.
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 mosai...

Leiden ; Boston : Brill, 2016. 1 online resource (570 pages) : illustrations (some color), maps, charts. text txt rdacontent computer c rdamedia online resource cr rdacarrier History of science and medicine library ; v. 52 Bibliographic Level Mode of Issuance: Monograph English Includes bibliographical references and index. Description based on print version record and CIP data provided by publisher; resource not viewed. 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. Their accuracy exceeds medieval mapping capabilities. These sub-charts show a remarkably good agreement with the Mercator map projection. It is demonstrated that this map projection can only have been an intentional feature of the charts’ construction. Through geodetic analysis the author eliminates the possibility that the charts are original products of a medieval Mediterranean nautical culture, which until now they have been widely believed to be.
