This exceeding rare and spectacular piece is a superb example of a surviving 17th century wall map. Designed to awe the beholder with their beauty and decorative detail, wall maps represent the pinnacle of "Golden Age of Cartography". [see Shirley "The Mapping of the World" No. 435] Despite being signed "G.Blaeu" in the title banner, the derivation and sources for this map are obscure. Even its place of publication, probably Venice, is uncertain. While the map, like virtually all 17th century wall maps is based on Blaeu's wall map of 1605, it bears a striking resemblance to the 1629 map of Nicolaes van Wassenaer, of which only one example is known. The inclusion of the name "G.Blaeu" is a graphic testament to his continuing significance to potential map buyers even twenty-seven years after his death.
