BLAEU, W. - Borbonium, Ducatus. Bourbonnois.

A very decorative map with beautiful cartouches of this central province of France, once the seat of the powerful Dukes of Bourbon. It's ancient capital was Moulins, the region is roughly situated in the modern departments of Allier at part of Cher. The map was made by W. Blaeu, one of the most famous map publishers of the seventeenth century.
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".

From an incomplete example of the 1634 German text edition of Blaeu's "Novus Atlas", previously owned by Johann Christoph Gesen (1639), Johann Rudolph von Metzradt (1651), Friedrich August II, King of Saxony (1797-1854).
P. van der Krogt mentions two variants for the German 1634 text edition and only two examples containing proof states (Bad Münstereifel and Gotha).
