Probably the painting exhibited by Desnos at the Salon of 1838 (# 503) with the description (in French) : <i>Madame de la Vallière - Avant d'entrer au couvent, elle vient se jeter aux pieds de la reine pour obtenir son pardon.</i>
The painting would therefore depict Louise de La Vallière, mistress of King Louis XIV, asking forgiveness from the latter's wife, Queen Marie-Thérèse, before taking the veil.
