This portrait is sometimes described as that of Ange Hyacinthe Maxence, baron de Damas, minister of Louis XVIII e.g. the site of La Réunion des Musées Nationaux.

Others consider this work to be a self-portrait of Jean-Baptiste Isabey. There is certainly some likeness between the sitter and Isabey, cf the portrait of Isabey painted by François Gérard below.

This image was published in Les Contemporains, issue № 1003 of 31 December 1911. It accompanied an article by J. Furet, Jean Marie Collot d'Herbois, conventionnel (1750-1796).

The same portrait is often described as a work of François Bonneville representing Fabre d'Eglantine (see below).

It is however more likely to be a work of François Bonneville representing Jérôme Pétion. Cf portrait of Pétion below.
