I was wondering what you mean by the symbolism being shallow? I ask casue this is the deck that I bought. I could not remember at the time of my last post here what the name was but I brought the cards with me to work so that i could bring them here to the library so that I knew I would not forget its name this time lol. Anyway, I really like this deck for some unknown (to me) reason but I got a hell of a good energy serge when I picked them up ( not just the first time either but everytime I pick these cards up.
The symbolism seems shallow to me because of the simplicity of the artwork. There's not a lot of depth to the pictures and not a lot of fine detail to sink your teeth into. There are a few interesting symbolic choices on some of the cards (the author's decision to depict a rose bud tied to the arm of the fool, for instance), but to me there just isn't a lot of detail there (unlike the Thoth deck, in which I am still finding new hidden characters and details in the cards after 15 years of using them).
Also, not a lot of the cards relate to eachother, as far as I can tell. In some decks, certain details in one card will point to another card all together. For example, in some decks, the Emporor's legs are crossed so that they kind of look like the number 4/Alchemical symbol for sulpher...and in turn, the Hanged Man's legs make an inverted number 4/Sulpher symbol on that card. These references to other cards can give clues to the esoteric meanings of their companions, so I appreciate those relationships when deck creators include them. (I also love it when artists of newer decks add new relationships that I've not seen before).
So that's why I call the Londa's symbolism shallow -- it doesn't have the same level of detail and complexity as other decks I've seen.
However (and here's the big HOWEVER with flashing lights and rolling drums and dancing girls and boys), this is all me and my opinionated self talking from my frame of reference and my likes and dislikes regarding art and symbolism. You may see whole worlds in the Londa deck that just don't manifest for me. That's why there's so many decks out there -- because there are so many eyes to look at them!
Hope this helped clarify what I meant!
