Lot Details
A brass and marble cannon sundial or noon day gun, French, circa 1800,
made for latitude 43 degrees 33 minutes, the circular marble base mounted with shaped gnomon, a large burning lens adjustable against a quadrant with calendar scale and a small signal cannon, 10½in (27cm) diameter

Footnotes

  • Cannon dials were popular throughout the 18th century. The burning glass would receive the sun's rays at noon and ignite a fuse on the cannon and thus fire the gun giving a signal for midday. All in the vicinity would then be able to adjust their pocket watches to the correct time.
