Joan Blaeu's world map from the Atlas Maior (1662-1664) represents the pinnacle of Dutch Golden Age cartography. The double-hemisphere map features elaborate decorative borders showing celestial diagrams, allegorical figures representing the four seasons and elements, and views of the world's major cities. The Atlas Maior was the largest and most expensive book published in the 17th century. Blaeu's workshop in Amsterdam was the world's largest printing operation.
