Rosalie Duplant, a famous Paris opera singer, began her career in 1763, retiring from the stage around twenty years later, prior to the date this portrait was made. She particularly excelled in the opera Atys, composed by Niccolò Piccinni in 1780, which is evoked in the open score on the music stand of the pianoforte. It is even possible to see the inscription “Merken Parisiis fecit 1785”, an allusion to the instrument manufacturer Johann Kilian Merken.
