Tabula moderna Tartariae: an unprinted map of Ptolemy's 1525 Strasbourg edition
Cartographica Helvetica 47 (2013) 37–49
The described manuscript map (47 x 36 cm) is unsigned and bears no date. It shows the area of Tartary from northern Scandinavia to central Asia north of the Caspian Sea. The text on the back of the map refers to travels to Persia from 1474 to 1477 by Venetian diplomat Ambrogio Contarini. An analysis resulted in the following conclusions:
A conclusive set of evidence and arguments leads to the interpretation that the 'Tabula moderna' was a draft meant for publication in Ptolemy's 1525 Strasbourg edition by the publishing house of Johann Grüninger. It dates from the turn of the year 1524/25 and can be attributed to Laurent Fries. The careless and amateurish compilation of maps and texts corresponds exactly to the procedure found in other geographic works by Fries. The result, however, was neither a final draft nor a printed map.
