Detail shot of the Countess of Castiglione. Pierre-Louis Pierson and Aquillin Schad, La Frayeur (Fright), 1861-64, salted paper print with gouache, 2015.395. Another image from the fascinating Grand Illusions exhibition. Virginia Verasis, Countess of Castiglione, mistress of Emperor Napolean III, posed for this “staged” photograph. According to the label, she was a notorious beauty known for her flamboyant self-presentation . . . (reminds me a bit of Madame X, Virginie Gautreau).
