Martin-Guillaume Biennais (1764-1843) of rue St. Honoré, held the post under Napoleon of Orfèvre de Sa Majesté l'Empereur et Roi.
Watercolour designs from the Biennais workshops, now in the Bibliothèque des Arts Décoratifs, Paris, are attributed to Charles Percier, co-author with Pierre Fontaine of Recueil de Décorations Intérieures, 1812, which illustrates related 'Grecian' furnishings to the present lot.
A related petite psyché, bearing the stamp of Biennais, is recorded in the collection of Prince Napoleon. The same Antique Janus-therm supports appear on another petite psyché in the collection of Mme. H. Lefuel, illustrated in Denise Ledoux-Lebard, Le Mobilier Français du XIX Siècle, 1984, pp. 86, 87, and related supports appear on another shield-shaped mirror at Malmaison, illustrated in S. Roche, Miroirs, Paris, 1956, fig. 97.
