A good example of an important atlas. Thomas Jefferys (1719-71) was arguably the most important English cartographer during the eighteenth century. A publisher, engraver, author and geographer of some note he was appointed Geographer to Frederick Prince of Wales in 1748, and later to King George III. It was during the Seven Years’ War that Jefferys made a name for himself as an authority on North American cartography. Many of those important maps are present in the atlas offered here. His other great contribution was in English County cartography being involved with a number of county atlases. But it was his large scale maps of the counties that extended his finances too far. His map of Devonshire in 1765 won the first ever prize of £100 offered by the Royal Society of Arts. By 1766 he was forced into bankruptcy. To survive Jefferys entered into partnerships, the most important of which was with the London map and print seller Robert Sayer. In 1768 his attention turned back to America when they published ‘A General Topography of North America and the West Indies’. When Jefferys died in 1771, Sayer purchased a large amount of his stock. Sayer by then was in partnership with John Bennett. Together they continued to publish Jefferys’ maps, compiling amongst other atlases ‘The American Atlas’ offered here.

This is arguably the first American ‘state’ atlas displaying as it does for the first time all of the American colonies in great detail. Ristow stated that as a ‘… major cartographic reference work it was very likely consulted by American, English and French civilian administrators and military officers during the Revolution.’ The first edition is dated 1775 with further issues in 1776, 1778, 1782, 1794 and 1800. The dates on the actual maps can be later than that on the title page. This is an example dated 1776 but with four additional maps bound at the end. The latest date on these is 12 March 1777 on the Faden plan of the ‘City and Environs of Philadelphia’ after Scull and Heap. Amongst the significant maps included in this atlas are the surveys of the American continent in 6 sheets, Nova Scotia with Cape Breton Island, and New England by Braddock Mead (alias John Green), the English edition of William Scull’s map of Pennsylvania, Virginia by Joshua Fry and Peter Jefferson (father of Thomas, the third US President), the Carolinas by Henry Mouzon and Lieutenant Ross’s map of the Mississippi River. The four additional maps are John Montresor’s map of the ‘Province of New York’ 10 June 1775, William Brasier’s survey of Lake Champlain and the upper Hudson River valley and Faden’s plan of the ‘City and Environs of Philadelphia’ after Scull and Heap.

The finest addition is Andrew Dury’s ‘Plan of Boston’ dated 12 March 1776. Nebenzahl states that it ‘clearly reveals the situation of the siege of Boston by the Continental army nine months after Washington assumed command’. It features details of the Battle of Bunker Hill and the positions of both forces. Ironically it was issued just five days before the British evacuated the city. A full list of contents is available.
