Geneviève-Françoise-Laurette Randon de Malboissière as Melpomene

Louis-Michel van Loo's portrait of Geneviève-Françoise-Laurette Randon de Malboissière as Melpomene, painted in 1765, exemplifies the Rococo convention of the portrait en déguisement—the fashionable practice of depicting aristocratic and bourgeois sitters in allegorical or theatrical disguise. Melpomene, the muse of tragedy, gave the sitter both intellectual dignity and dramatic presence, and the format was particularly popular for wealthy young women whose education included music and literature. Van Loo had served as first painter to the Spanish court before returning to France, where his reputation in state and society portraiture gave him access to the sophisticated Parisian clientele for whom such elaborate portraits were both social currency and personal statement. The sitter, from a distinguished French family, was identified with literary interests that made the tragic muse an appropriate choice of costume identity. By 1765 the strictest Rococo decorative sensibility was beginning to give way to Neoclassical sobriety, but court and society portraiture continued to embrace playful mythological self-presentation for another generation.

Van Loo renders the theatrical costume with the technical fluency for rich fabrics that his training and Spanish court experience had developed to a high level. The Melpomene attributes—tragic mask, mourning draperies—are treated as objects of beauty rather than merely symbolic identifiers, their rendering as carefully worked as the sitter's face and hands. The compositional format follows the tradition of three-quarter-length portraits with a gesture toward a symbolic object that van Loo had practiced extensively.
