Joaquina Téllez-Girón y Pimentel (1784-1851) was the daughter of the Duke and Duchess of Osuna and Marchioness of Santa Cruz by her marriage to José Gabriel de Silva y Walstein in 1801. A friend of poets and literati, she was one of the most admired women of her time.
Goya presents her wearing white crêpe and reposing on a canapé upholstered in red velvet. She is crowned with grape leaves and clusters. This headdress and the lire -shaped guitar identify her as Erato, the muse of Love Poetry- a clear reference to her love of poetry and music.
