Huge John Rocque Map of London 1746, Republished By Harry Margary

About the Item

Late twentieth century Harry Margary republication of John Rocque's celebrated map of 1746, 'A plan of the cities of London and Westminster and borough of Southwark'. Twenty-four framed sheets, in excellent condition, overall dimensions when presented in a 'tight-hang', width 416cm, height 214.5. Each frame height 71.5cm, width 52cm. John Rocque was of French Huguenot stock from Monosque in Provence and moved to London with his parents in the early eighteenth century. London at this time was an expanding city which had grown unchecked and had no new survey made since that of William Morgan in 1692. The idea to do a new survey had come from the engraver George Vertue, but he and John Rocque could not come to an agreement. Rocque, began the painstaking project in 1737 in partnership with another engraver, John Pine, to survey the central area of London and Westminster. Using a theodolite supplied by Jonathan Sisson, bearings were taken from church steeples, then angles were taken at the corner of streets and measured with a chain. Finally distances were taken along the streets, but it was first found that these measurements did not tally with the trigonometry. Such a huge task had never been undertaken before and this was one of the many problems encountered. Differing place names also proved difficult, with about five thousand names having to be plotted onto the map. They overcame this by recording them the shop then verifying them later with existing documents. Due to the huge size of this map there is a low survival rate for the original examples so a full-size facsimile was produced in 1971 by Harry Margary. Harry Margary, a Senior Civil Scientific Engineer for the Admiralty and self-professed inventor, produced this full-size facsimile of the famous John Rocque map in 1971. The original 18th century map never joined properly due to paper shrinkage in the printing process and only the constituent copper plates joined. For this lithographically printed version Margary altered some of the edges so the maps would join and significantly cleaned up the image area. Interest in Rocque’s map has increased over the years and in 2014 an original complete example, sold at auction for £85,000.
