The Austrian medium Rudi Schneider was investigated in 1924 by the physicists Stefan Meyer and Karl Przibram. They caught Rudi freeing his arm in a series of séances. Rudi claimed he could levitate objects but according to Harry Price a photograph taken on April 28, 1932 showed that Rudi had managed to free his arm to move a handkerchief from the table. According to Warren Jay Vinton, Schneider was an expert at freeing himself from control in the séance room. Oliver Gatty and Theodore Besterman who tested Schneider concluded that in their tests there was "no good evidence that Rudi Schneider possesses supernormal powers."
There are many ways of working with the deck. You should choose your own deck by being drawn to it intuitively. There are layers upon layers of systems to learn, including Kabbalah, the tree of life, colour scales, Hebrew letters, numerology, pathways, symbolism, alchemy, astrology, mythology and learning to meditate with each card directly. The more layers you learn the deeper your knowledge and insight into the cards.
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.
