This is an example of the ‘Chorographia Britannia’ in full early wash colour. First published in 1742 this is a later edition bearing the revised imprint of John Clark on the title page. He had joined Charles Hitch and William Henry Toms (fl.1723-61) in the ownership of the atlas by November 1745 when a newly worded advert was placed in the ‘Evening Post’. Clark died in April 1746 and was succeeded by his wife Anne. It is the first pocket size English county atlas published in the eighteenth century. It is surprising it took so long for one to be published considering the runaway success of the ‘Britannia Depicta’ of 1720. Two similar atlases were to be published shortly after, the ‘Geographia Magnae Britanniae’ by Thomas Osborne, 1748, and the ‘Small English Atlas’ by Thomas Kitchin and Thomas Jefferys, 1749.
