Gerard Barbier was the one who created the Ge Oracle, a divinatory card game that is very easy to use. Its symbolism is open to everyone: amateurs as well as professional clairvoyants can use it to elucidate their predictions. You can do a reading for yourself, or for a consultant. There are no rules. Consider the Ge Oracle as a clairvoyance tool.

The Ge Oracle is made up of 61 cards. Some cards can have different meanings. The meaning changes depending on whether they are drawn rightside up or reversed. Each card has a number. The number is printed in the top right corner as well as in the bottom left corner of the card. But, a so-called "simple" card is drawn, it will only have a number in the top right.

Next come the Season cards, which also carry much importance. Spring is number3, Summer is number24, Winter is 41, and Autumn, number 55. The season tells you when an even will occur. If multiple season cards are drawn, the event will occur between two seasons. But, if you draw two season cards side by side in a row, the event will be put off for six months. If you get three season cards in a row, count on nine months. If four season cards, the prediction will come to pass in at least one year.

After the Season cards, we have the Character Cards. They are numbered 45,46,47,48,49,50,51, and 52. Whether they are drawn rightside up or reversed, their meaning does not change. They simply give detail on the physical aspects of the people involved: whether they are blond, brown-haired, or redheaded.

The Ge Oracle can be read in a Cross spread, like in the Marseille Tarot. For a more precise response and more detail, you can do a 6-card reading, or, to do a reading on your personality, you can do a 5-card reading with the cards laid next to each other. A pyramid-shaped reading is also possible in order to focus on a specific area. A reading with 7 cards can be done to get an answer to a precise question. The answer will either be a yes or a no. And, finally, there is a 16-card reading. Depending on the method used, the reading will be more or less exact. For simple questions, a 6 or 7-card reading will be enough. But, if you want more details about your future in specific areas (health, work, love, ect.),it would be best to use a more elaborate method.
