Summary[edit]

Description
English: Chappe-system for optical conveyance of messages using special semaphore towers (see Semaphore line). The code illustrated is almost certainly fictitious. It first appeared in the Gentleman's Magazine, November 1794, p. 992. The author explicitly states that he does not know the actual code because the French kept it secret.
Deutsch: Chappe-System zur optischen Übermittlung von Nachrichten mittels spezieller Telegrafentürme (siehe Optische Telegrafie).
Français : Système Chappe pour la transmission des informations avec les tours Sémaphore (voir Sémaphore (communication)). Le code illustré est presque certainement fictif. Il est apparu pour la première fois dans le Gentleman's Magazine de novembre 1794 (p. 992). L'auteur déclare explicitement qu'il ne connaît pas le code réel parce que les Français l'ont gardé secret.
