Namurcum comitatus / Petrus Kaerius cælavit.

The central focus is a copperplate engraved map of Namurcum (Namur), showing the Meuse River winding through a landscape of hills, woodland, and urban centers. The map is bordered by four blocks of dense, typeset Latin text that provide historical and geographical context for the territory. The cartographic style utilizes traditional cross-hatching to indicate relief and stylized symbols to represent fortified towns and smaller rural dwellings. The overall composition is a typical 17th-century 'carte à texte', where the visual representation is framed by scholarly apparatus.

Pieter van den Keere (Petrus Kaerius) was a prominent Dutch engraver and cartographer whose work, particularly his collaboration with Petrus Bertius on 'Germania Inferior', was central to the golden age of Dutch cartography and the systematic documentation of the Low Countries.
