Mentalism
Mentalism is a performing art in which its practitioners, known as mentalists, appear to demonstrate highly developed mental or intuitive abilities. Performances may appear to include hypnosis, telepathy, clairvoyance, divination, precognition, psychokinesis, mediumship, mind control, memory feats and rapid mathematics. Mentalists are sometimes categorised as psychic entertainers, although that category also contains non-mentalist performers such as psychic readers and bizarrists.
Background
Much of what modern mentalists perform in their acts can be traced back directly to "tests" of supernatural power that were carried out by mediums, spiritualists and psychics in the 19th century. However, the history of mentalism goes back even further. Accounts of seers and oracles can be found in works by the ancient Greeks and in the Old Testament of the Bible. Among magicians, the mentalism performance generally cited as one of the earliest on record was by diplomat and pioneering sleight-of-hand magician Girolamo Scotto in 1572. The performance of mentalism may utilize these principles along with sleights, feints, misdirection and other skills of street or stage magic.
