Jachim and Boaz
1 - Jachim and Boaz on the card is mentioned in Elephias Levi's book, Rituals and learning of the higher Magic (I don't know if the title is correct, the book I have is written in Dutch)
Wait used a lot of Levi's discriptions when he designed his cards. A lot of websites write that Wait was the first to use the black and White pillars. But this can't be thrue, Levi's description came first.
I would really like to see the deck that Levi used, I feel like it's the missing link between the old cards and the new.
I just found this, haven't checked it yet:
'These appear in the description of Solomon's Temple, 1 Kings 7:15-22 and 2 Chronicles 3L14-17 '
Finally my opinion,
The White Pillar says:
It's ok to lose the J and B when you know what the pillars mean. In this case you still have the pillars as a symbol, so its ok. The card does look better.
The Black Pillar says:
If people see the B and J, and they don't know what it means, they might be encouraged to do some more research. It worked for me that way. Maybe you could find alternetive symbols for them?
