French Empire Antique ormolu & verd antico marble mantel clock of "The Astronomy Lesson" by Jean-Andre Reiche. The fire and mercury gilt ormolu is in excellent condition and is entirely original. This is the largest and most impressive of the genre of clock designs that Jean-Andre Reiche made for the Emperor Napoleon in 1807. This features a governess and her pupil sitting at a table with an astrolabe between them with the governess pointing at a star chart while the pupil holds a book in her hand. Both sit on fine Empire chairs which are highly decorated with applied ormolu mounts of scrolling forget-me-not flowers and female masks. These finely cast and finished young women sit on a shaped ormolu base decorated with applied ormolu mounts of beribboned cupids carrying scientific instruments. To their left is an applied mount of a table globe and to their right a superb mount of an elaborate astronomical telescope. To each end is an applied mount of anthemion. This all sits upon an antique vert shaped marble base standing upon six ormolu toupee feet. Beautiful white enamel convex dial with original blued steel moon hands. Signed on the dial above 6 o'clock "Jacquin Rue Montmartre No 141 Paris". 8 day movement, countwheel striking on a fine cast bell, timekeeping regulated with silk suspended pendulum.
