1) The level of historical cartography, referred to below as "classical": These maps can be found in schoolbooks, national histories, historical atlases, but also in non-fiction books and other types of publications aimed at both historians and a wider public. They predominantly date from the 20th and 21st centuries; in terms of content, they usually remain superficial.
2) Contemporary cartography of the 17th century: Here we are interested in three periods. First, the depictions of the duchy before the conclusion of the Peace of the Pyrenees. Then, in a second stage, the maps that first record the border changes resulting from the peace treaty. Was this immediately after the conclusion of peace, or only after a long time? Who made the maps and on whose commission were they created? Does the depiction correspond to the agreements made in the peace treaty, or are there differences that need to be evaluated?
A third section will examine the question of when subsequent map series began to adapt the changed border lines. Were there possible delays or different representations? If so, did this occur due to ignorance or political motivation?
3) A newly created map series: Using the methods of historical cartography, the actual border shifts are traced in eight time periods as detailed and chronologically accurately as possible. This allows, for the first time, a representation of the dynamics of the process in space and leads to a reassessment of the effects of the Peace of the Pyrenees on the Duchy of Luxembourg
