"As early as 1520, Spanish settlers in Panama had heard tales of a powerful civilization rich in gold that lay to the south, and in 1522 an expedition was organized to find this land and the people called Birú or Pirú in the south.
In 1524 Francisco Pizarro led the first of his expeditions that led ultimately to the discovery and conquest of the Inca empire which extended over wide areas of modern Ecuador, Peru, Bolivia and part of Chile.
Pizarro obtained from Atahuallpa, the head of the Inca empire, a huge ransom of silver and gold that made Spain rich almost beyond the most inventive dreams of the Spanish conquerors, and once the mountain city of Cuzco was captured in 1533, the Spanish hold over much of South America was virtually complete." (John Goss)

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".
This map is from the Novus Atlas, Das ist, Abbildung und Beschreibung von allen Ländern des Erdreichs. Gantz vernewt und verbessert.

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).
