No doubt a great importance in the paranormal field is the problem of fraud. The field of psychic research and spiritualism has been so notoriously full of charlatans, such as the Fox sisters and Eusapia Palladino–individuals who claim to have special power and gifts but who are actually conjurers who have hoodwinked scientists and the public as well–that we have to be especially cautious about claims made on their behalf.
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.
