From the 'Novus Atlas'. Joan Blaeu (1598-1673) is one of the most famous of the Dutch cartographers. The fourth volume of his atlas focused on England and Wales. Blaeu established his firm in 1599 as instrument and globe makers. He went on to produce some of the highest quality atlases ever published. The lower right depicts a pleasant scene of a gentleman using a pair of dividers presumably on a map held up by a cherub. Skelton 28; Van der Krogt, P. (Atlantes) 5560:2.
