In 1960, psychic investigator Andrija Puharich and Tom O'Neill, publisher of the Spiritualist magazine Psychic Observer, arranged to film two seances at Camp Chesterfield, Indiana using infrared film, intending to procure scientific proof of spirit materializations. The medium was shown the camera beforehand, and was aware that she was being filmed. However, the film revealed obvious fraud on the part of the medium and her cabinet assistant. The exposé was published in the 10 July 1960 issue of the Psychic Observer.:96–97
The article about this phenomenon in Encyclopædia Britannica places emphasis that "… one by one spiritual mediums were convicted of fraud, sometimes using the tricks borrowed from scenic "magicians" to convince their paranormal abilities". In the article it is also noted that "… the opening of the wide ranging fraud happening on spiritualistic sessions caused serious damage to reputation of the movement of a Spiritualism and in the USA pushed it on the public periphery".
In 1908 at a hotel in Naples, the psychical researchers W. W. Baggally, Hereward Carrington and Everard Feilding attended a series of séances with Eusapia Palladino. In a report they claimed that genuine supernatural activity had occurred in the séances, this report became known as the Feilding report. In 1910, Feilding returned to Naples, but this time accompanied with the magician William S. Marriott. Unlike the 1908 sittings, Feilding and Marriott detected her cheating, just as she had done in America. Her deceptions were obvious. Palladino evaded control and was caught moving objects with her foot, shaking the curtain with her hands, moving the cabinet table with her elbow and touching the séance sitters. Milbourne Christopher wrote regarding the exposure "when one knows how a feat can be done and what to look for, only the most skillful performer can maintain the illusion in the face of such informed scrutiny."
Yes, it was! When I used to work [there], I felt the spirits which were from the old days of the begining of the 19th century. Also, at the end of my shifts, the girls that worked with me would always ask me to read their palms. Considering the amount of energy that is required for palm reading, the Clubhouse was the perfect place for me to do it. I felt that the spirits there would appreciate me, considering the fact that I could feel them. I also felt a good energy. The spirits made me feel that I could make good money when I worked there.
A very large part is played by fraud in spiritualistic practices, both in the physical and psychical, or automatic, phenomena, but especially in the former. The frequency with which mediums have been convicted of fraud has, indeed, induced many people to abandon the study of psychical research, judging the whole bulk of the phenomena to be fraudulently produced.
The first documented tarot packs were recorded between 1440 and 1450 in Milan, Ferrara, Florence and Bologna when additional trump cards with allegorical illustrations were added to the common four-suit pack. These new decks were called carte da trionfi, triumph cards, and the additional cards known simply as trionfi, which became "trumps" in English. The earliest documentation of trionfi is found in a written statement in the court records of Florence, in 1440, regarding the transfer of two decks to Sigismondo Pandolfo Malatesta.
