The map's detailed depiction of these river systems and adjacent territories provides not only geographical information but also historical insights into the strategic importance of these regions. The inclusion of the Meuse River, for instance, points to its historical significance as a boundary and a route for trade and military movements. Similarly, the Rhine, Moselle, Main, and Neckar rivers have been pivotal in shaping the historical, economic, and cultural landscape of Western Europe.
Pierre, or Pieter, Mortier (1661-1711) was a Dutch engraver, son of a French refugee. He was born in Leiden. In 1690 he was granted a privilege to publish French maps in Dutch lands. In 1693 he released the first and accompanying volume of the Neptune Francois. The third followed in 1700. His son, Cornelis (1699-1783), would partner with Johannes Covens I, creating one of the most important map publishing companies of the eighteenth century.
