5.25 x 4 in., f 6.5 x 5.25 repousee frame brass, oil on thin bone plate. This hand painted portrait miniature on shaved bone plate depicts Emperor Napoleon I standing in full coronation regalia after the celebrated 1805 official portrait by Baron Francois Gerard, the composition showing Napoleon crowned with gold laurels, holding the scepter aloft in his right hand, wearing the ermine trimmed crimson mantle over white embroidered robes with the imperial throne visible at right and the hand of justice resting on a cushion at left. The work is signed B. Francois Gerard at the lower left of the bone plate, the B denoting Baron -- a title conferred on Gerard by Napoleon in 1809 -- indicating the work was produced or signed after that date and consistent with the practice of producing miniature versions of the famous coronation composition on bone and ivory for aristocratic and diplomatic patrons. Gerard was the preeminent portrait painter of the Napoleonic court and the Bourbon Restoration, his 1805 coronation portrait of Napoleon becoming the official image of the First Empire and reproduced extensively in oil, engraving and miniature form throughout the early 19th century. The miniature is presented in an original pierced gilt brass frame with decorative Gothic arch frieze, corner mounts and shaped hanging ring at the apex, the frame consistent in character with French Empire and mid 19th century decorative metalwork.
