French Napoleon III Grisaille Enamel Plaque, circa 1865–1880, executed in the centuries-old grisaille enamel technique, this elegant oval plaque is painted in luminous shades of white and gray over a rich cobalt blue ground, the enamel fired repeatedly upon a convex copper support to achieve remarkable depth and permanence. The romantic classical scene, inspired by an earlier Italian Renaissance composition, depicts a reclining armored hero attended by a graceful female figure amid an idealized architectural landscape. The plaque is housed in its original richly gilded carved wood frame, which complements its refined nineteenth-century aesthetic.
