Marie-Adélaïde de France, dite Madame Adélaïde

Executed in oil on canvas, the painting employs a dark, almost velvety background that heightens the luminosity of the figure’s garments. While Vallayer‑Coster is chiefly remembered for her still‑life compositions, this portrait adopts Rococo sensibilities—soft lighting, graceful contours, and an emphasis on surface texture.

Vallayer‑Coster, admitted to the Académie Royale de Peinture et de Sculpture in 1770, created this work shortly before the French Revolution. It entered the Versailles holdings as part of the royal inventory and has remained there, offering insight into the artist’s occasional forays into portraiture for the monarchy.

The portrait was produced at a moment when the Rococo style was giving way to neoclassical tastes, yet the painting retains the ornamental delicacy typical of the earlier movement. Its creation coincides with the waning influence of the French court, marking a transitional period in both artistic and political history.
