Teacher and publisher Jean-Baptiste Alliette wrote his first book on the tarot in 1791, called “Etteilla, ou L’art de lire dans les cartes,” meaning “Etteilla, or the Art of Reading Cards.” (Alliette created this mystical pseudonym “Etteilla” simply by reversing his surname.) According to Etteilla’s writings, he first learned divination with a deck of 32 cards designed for a game called Piquet, along with the addition of his special Etteilla card. This type of card is known as the significator and typically stands in for the individual having their fortune read.

Furthermore, she learned her trade from the mediums Frank Herne and Charles Williams, who were notorious for their cheating." Also see M. Lamar Keene. (1997). The Psychic Mafia. Prometheus Books. p. 64. ISBN 978-1-57392-161-9 "The most famous of materialization mediums, Florence Cook – though she managed to convince a scientist, Sir William Crookes, that she was genuine – was repeatedly exposed in fraud. Florence had been trained in the arts of the séance by Frank Herne, a well-known physical medium whose materializations were grabbed on more than one occasion and found to be the medium himself."
Clairvoyance, where you see images, objects, people and scenes presented to you in your mind's eye. For this it's best to build up a bank of symbols (archetypes) for spirits to present to you that represent certain meanings to you. Your mind is an open book to the spirit world as long as you allow it. Your personal language of symbols and their meanings is accessible to them. As an example, if you decide that a horse represents freedom to you, if spirit shows you a horse then the topic is going along the lines of the client needing more freedom or gaining more freedom. Other accompanying symbols should clarify this.
Celtic Cross Tarot card reading predicts your future by reading the cards. This is different from prophesies using calculations of date, time and year of birth. Each prediction or card selection may not indicate the same result. The accuracy depends on your intention and concentration at the time of selection. Thus, it is very important to concentrate hard to achieve the most significant outcome.
