"ONE OF THE MOST AUTHORITATIVE AND COMPREHENSIVE ATLASES OF AMERICA..." (Walter Ristow)
First issue of the 1776 edition, issued before the Battle of Lake Champlain, and published one year after the first edition of 1775, most maps in this atlas are dated 1775, with some dated 1774. A very important atlas of the Revolutionary war era, with large maps of 11 of the 13 colonies and of French Canada.
Jefferys was geographer to the Prince of Wales, later King George III, and the leading map supplier of his day. His American Atlas is the most important 18th-century atlas for America, described by Walter Ristow as a "geographical description of the whole continent of America, as portrayed in the best available maps in the latter half of the eighteenth century... as a major cartographic reference work it was, very likely, consulted by American, English, and French civilian administrators and military officers during the Revolution."
"This atlas by Jefferys was the chief publication used by English and American officers during the American Revolution" (Karpinski). The geographical knowledge of America represented here not only affected the strategy of the Revolutionary Wat, but influenced the course of future treaty negotiations and boundary disputes.
The atlas contains a number of important maps, including Braddock Meade's "A Map of the Most Inhabited Parts of New England," the largest and most detailed map of New England yet published, and Samuel Holland's "The Provinces of New York and New Jersey." Holland was surveyor for the northern American colonies. Joshua Fry and Peter Jefferson's "A Map of the Most Inhabited part of Virginia" is the best colonial map of the Chesapeake region. Lieut. Ross's "Course of the Mississipi" is the first map of that river based on English sources. Jefferys died in November 1771 and his successors, Robert Sayer and John Bennett, gathered together these separately published maps to form The American Atlas.
