Corpus Hermeticum

I wanted to see what, if any, systematic theology there might be behind tarot reading. And I was struck that almost as soon as Europeans started using tarot decks for cartomancy, they attributed the practice to Egypt and the Hermetic tradition - and this was before they started putting Hebrew letters and Egyptian themes on the cards. Our scholarship of ancient and medieval religious texts has greatly developed since the 1700's, and now I am peering down into a deep, dusty rabbit hole.
