Namurcum comitatus.

Very rare map of the province Namen by Cornelis Danckerts. Depicting the region around the city of Namen/Namur based on the once-secret map of Jacques Surhon (ca. 1555). Decorated with a figurative title cartouche featuring a coat of arms and four putti, an unusual compass flanked by a surveyor, and a large scale of miles cartouche.
This map was found in a French composite atlas likely assembled and published around 1640 in Paris.

In the first half of the 17th century the publishing house Hondius / Janssonius / Blaeu dominated the map publishing in Europe. It is known that at the beginning of the 17th century the French publishers went to Amsterdam, buying those maps not available in Paris.
The Amsterdam publisher Cornelis Danckerts the elder made selling trips to Paris and was associated with Melchior Tavernier, who became at the beginning of the 16th century the most important publisher in Paris. He was very much influenced by the Dutch and must have visited Amsterdam on a regular basis. In 1638 he paid 500 pounds to H.Hondius, and 1000 pounds to Willem Blaeu, most likely in payment for maps he sold in depot. (Fleury, Archives Nationale.s documents du minutier etc. (Paris 969), vol I.p.652).
J.Boisseau copied after or used maps by H.Hondius, J.Jansson, W.Blaeu and C.Danckerts in his "Theatre de Gaules" from 1642. (Reference : Imago Mundi 32. M.Pastoureau, Imago Mundi 32).
