Charles X Period Gilded-wood Diamond-shaped Mercury Barometer, France, Paris, Circa 1820

This diamond-shaped mercury barometer reflects the refined style of the Charles X period. Its unique shape and reverse-painted glass panel — adorned with gilded scrolls, stars, and foliate motifs on a purple and white background — are a clear expression of the neoclassical taste of the 1820s.

The reverse glass painting technique, which involves painting in reverse on the back of a glass panel to achieve depth and brilliance, lends this scientific instrument a distinct decorative appeal. The gilded motifs are typical of the era, shaped by the Restoration style, which drew inspiration from Antiquity while incorporating symbolic elements like stars.

This barometer originates from the Galerie Vivienne in Paris, a landmark inaugurated in 1823 and known for its elegant architecture and refined boutiques. Its provenance adds to the object's historical prestige.

More than just a meteorological instrument, this barometer embodies the 19th-century blend of art and science. It still bears the labels from a past sale at Christie’s, further enhancing its historical and collectible value.
