Rocque's important large-scale survey of London was the first 'post-fire' map to be made since William Morgan's plan of 1682, and the primary topographical record of mid-18th Century London. John Rocque, a Hugenot, had come to London c. 1730, and having trained as a surveyor and engraver made estate surveys of Kensington Gardens and Hampton Court. By 1737 Rocque had moved to mapping towns and counties, beginning his ambitious survey of the entire built-up area of London in 1737, which was to take nine years to complete. Cf. Howgego 96.
