BLAEU, G. - Le Gouvernement de l'Isle de France.

Very detailed map of Ile de France centered on Paris. Showing Beauvais, Compiègne, Noyon, Laon, Soisson, Vernon, Mantes, Pontoise, Meaux, etc.
Adorned with the royal arms in the upper left corner, a surveyor showing the surveying instruments to two cherubs in the lower left corner. And in the lower right part, a very decorative title cartouche surrounded by a couple with angels holding royal arms on top.
From early on Willem Jansz. Blaeu aimed of publishing an atlas to compete with the Hondius-Jansson Atlas. By 1630, he had published at least 17 folio size maps.
Blaeu was able to realize his plan soon after he had acquired the copper plates of the atlas maps by Jodocus Hondius. The "Appendix followed in 1630.
In 1635 he finally realized a "international edition" of a world atlas, the "Theatrum Orbis Terrarum".
