London: A Life in Maps will be accompanied by a virtual exhibition, available on the BL website, for people who can’t visit. Though the emphasis of the exhibition will be on the great cartographic images and panoramas of London and on the ways in which the concerns of Londoners through the ages are reflected in maps, there will be a few items that may be of special interest to map specialists (in addition to rarities like one of the original copperplates for the “Copperplate Map” of London of the late 1550s, or the sole survivor of the manuscript cartographic survey of London prepared immediately after the Great Fire of 1666 or the sole complete example of Thomas Milne’s Land-Use Survey of 1800). These are the preliminary sketches, accompanied by a brief diary, by the statistician Gregory King for a survey of St Katharine’s by the Tower in May 1686. King was one of the surveyors employed by Ogilby and this demonstrates how closely his surveying methods conformed to the practices recommended by William Leybourne. Another cartographic “special” is a manuscript sheet from an abortive and hitherto undrecorded detailed survey of London apparently undertaken in about 1800 by Thomas Milne, possibly in competition with both Horwood and Ordnance Survey.
