This map of Lincolnshire is by Joan Blaeu (1598-1673), arguably the most famous of the Dutch cartographers. During the seventeenth century the Dutch held a dominant position in the production of high quality atlases. Joan Blaeu's father Willem, established his firm in 1599 as instrument and globe makers. He went on to produce some of the highest quality atlases ever published. This example is from the Dutch edition of the English volume first published in 1646. Lower left are the arms of the various nobles of the county. Carroll (1996) 12; Koeman Bl 45A p. 180; Van der Krogt, P. (Atlantes) 5330:2; Skelton (1970) 28 & 73.
