The "femme fatale" flourished in the Romantic period in the works of John Keats, notably "La Belle Dame sans Merci" and "Lamia". Along with them, there rose the gothic novel "The Monk" featuring Matilda, a very powerful femme fatale. This led to her appearing in the work of Edgar Allan Poe, and as the vampire, notably in "Carmilla" and "Brides of Dracula". "The Monk" was greatly admired by the Marquis de Sade, for whom the femme fatale symbolised not evil, but all the best qualities of women; his novel "Juliette" is perhaps the earliest wherein the femme fatale triumphs. Pre-Raphaelite painters frequently used the classic personifications of the femme fatale as a subject.
