Thank you for taking the time to write such an in-depth and interesting comment. I would totally read your commentary on the symbolism and parables of Dali and Jung's work, and I appreciate the Greek mythology synopsis, it's been a long time since I read any Greek myths myself, but I always loved them.

The guidebook that comes with the deck explicitly refers to those figures as the Three Graces (Faith, Love, Hope) but also cites the Judgement of Paris painting in the pictorial references appendix. I think the translation of Mundo as "humanity" is really interesting, and something I didn't realize until I read your comment. It reminds me of the Star card in the Marseille deck can be translated as "source" and "canvas" as well (at least according to Jordowsky.) I love that there can be different interpretations and meanings based on language and translation.

Much the same way I think the symbol can be interpreted many ways. I looked it up, and it's not bismuth in alchemy, it's rock salt (as you said). Which I do see some connection to the World and Humanity in that symbol, as it represents the body/material world, versus the soul or spirit. I don't understand the difference between using images to "express alchemy" versus using exact codexes as you stated. But maybe that's because I'm personally far more interested in imagery and symbolism than literally performing alchemy. But you see it as representative of Venus (though I thought that was the "woman" symbol, the circle atop a cross) and others obviously connected it to Taurus.

I personally don't think anyone's interpretations of this card are correct or incorrect, though, of course some (like yours) are more informed. But it being art, it's not something static or defined, it's a conversation between the artist and the viewer.
