Ptolemy’s Geography

The research project investigates the genesis of Ptolemy’s geographical catalog of places, in particular by considering its structure and the relations between the text of the Geography and its cartographical realization. Understanding Ptolemy’s working methods does not only shed light on the scientific practices in Antiquity; it enables also to set up new criteria for philologists to assess whether a coordinate in a manuscript is likely to be the original or has been corrupted during the transmission of the text.
