Astronomical clock

This imposing grandfather clock is the work of Antide Janvier, who built his first astronomical clock at the age of just 18 and made remarkable pendulum and regulator clocks for King Louis XVI, the revolutionary governments and Emperor Napoleon I, which earned him an apartment in the Louvre Palace. The clock, which is in a very beautiful cabinet, has 10 dials that indicate the times of sunrise and sunset, the phases of the moon, the date according to the Gregorian and republican calendars, the time in various cities of the world, leap years and the additional days of the republican calendar. In 1885 Jules Audéoud, who had a prestigious collection of timepieces, bequeathed it to the Conservatoire National des Arts et Métiers.
