These splendid salt cellars bear the stamp of Martin-Guillaume Biennais (1764-1843), one of the most famous French silversmiths of his time, official supplier of Napoleon Bonaparte and his court. Arriving in Paris in 1789, Biennais began his career as a cabinetmaker in a workshop located in Rue Saint-Honoré, bearing the sign of the Purple Monkey (Singe Violet), destined to remain his characteristic trademark. Following the abolition of the guilds imposed by the revolutionary laws of 1791 and 1797, which allowed anyone to take up the profession, Biennais decided to devote himself to silverware, initially producing small objects, such as toiletry sets and travel bags, and placing the foundations of a thriving business which, at the height of his success, would have led him to employ as many as six hundred people. The oval bowls in cut crystal, supported by winged sphinxes with a single leg, echo in a surprising way the salt shakers belonging to the great service in gilded silver performed by Biennais on the occasion of the wedding between Napoleon and Maria Luisa of Austria, commission documented by a payment dated 27 August 1810. As we can also observe in the two Coronini salt cellars, the objects produced by Biennais usually present sober shapes, inspired by the ancient, whose elegant functionality is not suffocated, but rather enhanced, by the refined decorations that are arranged on the architecture of the piece without compromising the perfect compositional balance.
