Eusapia Palladino was an Italian Spiritualist physical medium. She claimed extraordinary powers such as the ability to levitate tables, communicate with the dead through her spirit guide John King, and to produce other supernatural phenomena.
She convinced many persons of her powers, but was caught in deceptive trickery throughout her career. Magicians, including Harry Houdini, and skeptics who evaluated her claims concluded that none of her phenomena were genuine and that she was a clever trickster.
Her Warsaw séances at the turn of 1893–94 inspired several colorful scenes in the historical novel Pharaoh, which Bolesław Prus began writing in 1894.
