Abstract
The presentation dealt with the content analysis of the representation of waters on the three oldest maps of our territory from the 16th and 17th centuries. They are Klaudyan's map of Bohemia from 1518, Criginger's map of Bohemia from 1568 and Aretin's map of Bohemia from 1619.
The aim of the author was to identify and describe as much watercourse and areas as possible and possibly point out inaccuracies in their drawing.
