We have been unable to find anything about Robert Harman, this is the only work recorded by him in Tooley’s Dictionary of Mapmakers. The plan is dedicated to Sir Ralph Milbank, 4th Baronet of Halnaby (1689-1748) whose interests included mining and horse racing. Note the presence of “Stables for Running horses” on the map. Richmond is a Norman town whose wealth was built on the wool industry and the nearby lead mine, it prospered during the late seventeenth and early eighteenth centuries. The plan is engraved by Benjamin Cole (1697?-1783) and appears, according to the recent work of Worms and Baynton-Williams, to be his earliest recorded piece. The whole is finished off with the coats of arms of no less than 470 gentlemen. If these are all subscribers it is an indication of how important Richmond was in its day. THE ONLY KNOWN EXAMPLE IN PRIVATE HANDS. Provenance: private English collection. Tooley (1999-2004); Worms & Baynton-Williams (2011).
