Rocque’s monumental plan of London on 24 sheets

Rocque's landmark map of London, the largest to be published up to that time, at 26 inches to a mile, covering from New River Head, Limehouse, Walworth to Knightsbridge and Chelsea Waterworks. He used his experience as an estate-surveyor to introduce different hachuring to denote the usage of land, including pasture, formal gardens and orchards. According to the engraved text under the title, the surveying work was begun in March 1737; the completed map was first published in 1746. This second edition, with the same publication date on the plates and only minor alterations is dated c.1749 by Darlington & Howgego because Chesterfield House, completed that year, has been added. The incredible amount of detail on this map makes it an invaluable resource for the history of London in the reign of George II.
