Tracing back to the time of Aleister Crowley and others who immersed themselves in the occult, individual Major Arcana cards have been assigned to specific planets.
Student in astrology and Tarot, I do not always subscribe to traditional correspondence. For example, for me, the energy of Uranus corresponds much better to The Tower than Mars.
The argument for making Mars the “ruler” of the Tower is that the building of the Tower, described as the Tower of Babel, represents the pride of man and a structure of lies.
The image of the tower shows the lightning striking the crown at the top of the tower edifice, the crown being false materialism and the lightning bolt, the lightning of truth striking the edifice and violently moving the crown.
Mars represents the ego well. Mars is worthy in Capricorn where his ambition is transformed into concrete structure. And the flames emanating from the tumbling structure are consistent with the symbolism of Mars and its sign, Aries.
Finally, Wald Amberstone, co-founder of The Tarot School, likens the image of the card to a representation of a phallic symbol at the time of the climax.
It is certainly March.
But lightning, the sudden flash of consciousness, the crack when the structure collapses, are the hallmarks of Uranus.
Arthur Edward Waite in The Pictorial Key to the Tarot describes the previous card, The Devil, as “the fall in the material and animal state, while the other (The Tower) means destruction on the other side”.
Uranus’ energy is depersonalized. It is completely a product of the intellect and lightning is its hallmark.
The sudden lightning describes the functioning of Uranus as anyone who has experienced a transit of Uranus can attest.
Uranus is the first planet discovered that is too far away to be seen by the human eye without assistance. For centuries, astronomers have assumed that no planet extends beyond Saturn, hence the association of this planet with limits and boundaries.
Then, in 1781, astronomer William Herschel discovered Uranus with the result that the dominant world view of the Universe was turned upside down in the same way that Uranus’ transits caused upheavals and breakthroughs at the societal level and staff.
Uranian energy is a thunderbolt, coming from somewhere outside of ourselves, like lightning from above knocking down the tower and its crown.
In my opinion, Mars is a good descriptor for the actual tower of the map, but Uranus better describes the reality of the claimant when the map is drawn in an actual reading.
