About this work
Telescope from the signal post at Weesperpoort in Amsterdam, made in Paris, c. 1810. Fully extended, this telescope is about one-and-a-half metres long. This enabled the signalman to see for a distance of almost twenty kilometres. The range of the telescopes determined the maximum distance of the optical telegraphs.
