Notice: You will find in this section a very small part of what Philippe Camoin teaches in his School of Tarot. These explanations were placed on the Internet in order to allow students attending the course of his school to have a general overview of his teachings before coming to his course. This is so that they will benefit fully from the great wealth of other parts of the course which are not available on the Internet. Only a few minutes during the course is devoted to the information available on this site.
Until the beginning of the 20th century, the Tarot de Marseille was the standard Tarot deck, despite attempts by Oswald Wirth, Etteila, and Madame Lenormand, and others.
Numerous English and French experts have maintained over the last few decades that no secret codes existed in the Tarot, and that there were no longer any laws of the Tarot—in any case certainly not in the Tarot de Marseille.
This is one of the reasons that Oswald Wirth, Arthur Waite, Aleister Crowley and numerous other authors redesigned Tarot decks, which they claimed contained a symbolic and esoteric system which was lacking in the Tarot de Marseille.
In 1999, Philippe Camoin revealed that there was a secret structure composed of laws and secret codes in his Tarot de Marseille.
He revealed also that in order for these codes and this structure to appear, it was necessary to begin by arranging the cards in a structure called the Triple Septenaire, with the numberless card Le Mat (the Fool) placed apart from the 21 other Major Arcana. In this way Philippe Camoin uncovered hundreds of codes which had been unknown, henceforth known as the Camoin Codes.
The group of laws which he discovered in the Tarot and which were previously unknown are known as the Camoin Laws.
No one had discovered the structure or the whole formed by the Triple Septenaire and the Secret Codes of the Tarot were henceforth called the Camoin 3x7 Diagram.
