Detail from François-Hubert Drouais, Madame de Pompadour at her Tambour Frame, 1763-4 
The painting shows the one-time mistress of Louis XV in the last year of her life. Born Jeanne-Antoinette Poisson in 1721, she  became royal mistress and Marquise de Pompadour. She was a patron of the arts and letters and a leader of fashion who exercised considerable influence on the public policy of France.
The canvas is signed and dated on the work-table as begun in April 1763. The head, painted on a rectangle of canvas inserted into the painting, was presumably taken from life, and the rest of the picture completed in May 1764, the month after the death of Madame de Pompadour. Drouais’s painting is the last of numerous portraits of the sitter by some of the best-known painters of the day, including Boucher and Carle van Loo.

The sitter is the son of the Count and Countess of Altamira. Outfitted in a red costume, he is shown playing with a pet magpie (which holds the painter’s calling card in its beak), a cage full of finches, and three wide-eyed cats. In Christian art birds frequently symbolize the soul, and in Baroque art caged birds are symbolic of innocence. Goya may have intended this portrait as an illustration of the frail boundaries that separate the child’s world from the forces of evil or as a commentary on the fleeting nature of innocence and youth.
The picture may have been executed after the child’s death in 1792, since the imagery and sinister undertone seem more characteristic of Goya’s works of the 1790s.
