MAGICardology is the study of the ancient mystical science of playing cards. A pack of playing cards is what G. I. Gurdjieff, a mystic, philosopher, spiritual teacher, and composer of Armenian and Greek descent, called a “legominism”.

In the book, “MAGI: The Quest for a Secret Tradition”, author Adrian G. Gilbert states, “Gurdjieff believed that intelligent and knowledgeable people from bygone times had anticipated that this would happen. They had expected that their own civilization would, in time, be swept away and that profound ignorance would rule the Earth. Accordingly, they had encoded the most important aspects of their knowledge and belief systems into what Gurdjieff called ‘legominisms’. Often these were material structures, such as temples and pyramids, which could be expected to stand for thousands of years. In other cases, they were writings or even traditional songs and dances. There were even such legominisms as the pack of playing cards, which in its four suits of thirteen cards embodies, in shorthand, a whole range of esoteric ideas. By all of these methods he believed that knowledge had been preserved and passed on to future generations. He now set out on a series of long journeys in search of this lost knowledge.”

In Chapter XXV of his “The First Book”, Gurdjieff wrote:

“My dear and beloved Grandfather, tell me, please, what does the word Legominism mean?” Hassein asked.

“This word Legominism,” replied Beelzebub, “is given to one of the means existing there of transmitting from generation to generation information about certain events of long-past ages, through just those three-brained beings who are thought worthy to be and who are called initiates.

“This means of transmitting information from generation to generation had been devised by the beings of the continent Atlantis. For your better understanding of the said means of transmitting information to beings of succeeding generations by means of a Legominism, I must here explain to you a little also about those beings there whom other beings called and call initiates.”


The word “cardology” has been used for decades and has recently been brought back to life to describe the ancient mystical science of playing cards. It aligns perfectly with other systems of self-understanding based on one’s birth date, like astrology and numerology.

Research shows that Los Angeles, California astrologer Jan Eric (aka Jamie Brand Erickson, Joy Erickson) was the first to use this term in 1934 as part of his work “Astro-cardology” and copyrighted it with the Library of Congress on March 31st.


Jan Eric also advertised in The Billboard Magazine for his “fortune-telling game” for $1.25 per set.

In 1974, Donalie Fitzgerald, author of “Edith Randall’s Your Place in the Cards”,  also used the term “cardology” in her book on page 16 to describe the chart of birth dates and their associated cards.

Astrologer/Cardologer and International Association of Cardology Founding Member and Historian, Iain McLaren-Owens of Astro-Cards, has used the term “cardology” in his work too as a word to describe this system. Two of his books published in 2013 are called “Magian Cardology System – Card Chart Tables” and “Magian Cardology Readings Spreads with Explanatory Text + Cycles Date Tables”.

In 2015, Cardologer and International Association of Cardology Founding Member, Stefan G. Meyer PhD of, published his book, “Mysteries of Cardology”.

Since then numerous other classes, videos, and websites have embraced “Cardology” as the umbrella term that describes the science of the cards. Having one word to convey what this system is was long overdue as there are too many names currently used, making it hard for students and practitioners to be able to find this information online and offline.

Some names are more well known than others: 52 Keys, 52 Secrets, Ancient Calendar of the Magi, Ancient Science of the Cards, Astro-Cards, Atlantean Cards, Birth Card System, Book of Destiny, Cards of Destiny, Cards of Illumination, Cards of Truth, Card System, Destiny Cards, Egyptian Tarot, Life Cards, Little Book of the Seven Thunders, Love Cards, Magian Cardology, Magi Cards, Metasymbology, Mystic Card Science, Mystic Quadrate System, Mystic Test Book System, Oracle Cards, Personal Time-Map System, Sacred Symbols, Solar Cards, Soulmancing, the original Tarot Cards, Tarotology, The Ancient Book of Time, The Book of Life, The Cards, and The Cards of Life.

No matter what it’s called, everyone loves Cardology!
