Footnotes

  • Each hour, the twin vanes spell out the name of the maker, C-H-A-P-E. An army that can relay information quickly over distance is at an immediate advantage. In 1794, Claude Chappe, an engineer, developed what he believed to be a winning scheme. His plan was to site semaphore towers at strategic points across the countryside. Using their mechanical arms and pivoted terminal vanes, any message could be transmitted along the route. It was found to be quicker than using a relay of horses and messengers - a run from Antwerp to Amsterdam would travel via Merksem, Brecht, Meerle, Sprang, Waal, Houten, Utrecht, Vreelan and Ouderkerk in a matter of hours rather than days. A folder including images of semaphore towers, the alphabet and other information relating to this clock is sold with the lot.
