The story of desire can be as chaste as Botticelli's Venus or as voyeuristic as Susanna and the Elders. One of the most famous paintings about lustful temptation is the fully-clothed Madame X by John Singer Sargent. Sargent saw it as his ticket to fame and multiple portrait commissions; the subject, Virginie Amelie Avegano Gautreau saw it as a celebration of her status as the "It Girl" of Paris. Parisians, on the other hand, saw it as quite shocking, a much too graphic invitation to regard the socially elite Ms. Gautreau as a sex object.
After its display, Sargent left Paris never to return as a resident; Virginie slipped from her social pedestal and because something of a recluse. Sargent later recovered and achieved the fame and commissions he sought and the painting has become acclaimed as one of the best portraits ever painted.
My redhead may have something of Gautreau's pose and cool demeanor and to me, a bit of her rather icy allure.
