A highly significant plan of the City of London, based on a comprehensive survey made to assess the destruction caused by the Great Fire of 1666, extending from Moorgate to the waterfront, and from Fetter Lane off Fleet Street to Tower Dock. It comprises a substantial portion of the 6-sheet map drawn in December 1666, now lost, and its reduced version from early 1667, both produced by John Leake, who headed the team of surveyors, all named in the extensive header text, and originally engraved by Wenceslaus Hollar. It is noted for its detailing of every street down to the narrowest lane, in exact proportion, thereby allowing for viable reconstruction to be undertaken at the earliest opportunity. Vertue’s tribute to this instrument of momentous change for such an historic city is ornamented with seven inset views of important buildings, a small inset plan of London and Westminster, a compass rose, memorial and dedication cartouches, all under a title banderole stretching in two parts across the top.
