Numerology is a mystical art that has its roots beyond the dated history they tell us. I have studied esoterical numerology and it still flaws me at times. I agree the Ancient Greek philosophers were a very switched on bunch for their times! All the better for us!
Ahhh, the Marseille tarot. I have never used it but I know in predates the Cowley system where he tried his best to horn-shoe all the differing metaphysical platforms into the Tarot, also swapping Justice and the Strength cards… From a numerology point of view Justice fits far better with the 8 energy then Strength!
