Map of New York, Antique Map, 1777; Province de New-York en 4 Feuilles

This is a museum-grade reproduction of a fine example of the George Louis Le Rouge edition of John Montressor's monumental map of New York State. The years between the end of the French and Indian War and the start of the Revolution were a period of tremendous mapmaking in their American colonies. One of the most important regions was the area between the St. Lawrence River and the Hudson River and Long Island, an area which would also see significant military activity in both wars. John Montresor's very large map is printed on four sheets and depicts this region as well as substantial portions of New York, Vermont, Massachusetts, Connecticut, New Jersey and Pennsylvania. Montressor's map is the largest scale map of its time for the region. Its purpose was military rather than civilian use, with considerable emphasis on features affecting mobility: The regional network of roads, lakes, rivers and streams is quite detailed, while elevations are depicted effectively by means of hachuring, particularly in the Hudson and Mohawk River valleys. The map also delineates the boundaries of land patents in the Hudson Valley and towns in western New England as well as the locations of forts, farms, and various interpretations of the disputed New York – New Jersey boundary (which Montresor helped survey in 1771).
