Professor X's enthusiasm for the Thoth deck really shows. I myself use it, study it and am inspired by it. Many statements here put things into a more down-to-earth and universal perspective of the deck, and rightly so.
Coming from an artist's point of view, I am wary of mythologizing the greatness of our forerunners. One of the biggest examples in Art history is Michelangelo, where much has been written in a romanticizing fashion, deifying the man into heights which we can't possibly reach ourselves. Its a great disservice to future artists who aren't interested in myth, but technique. I believe it was Issac Newton who said something like 'They may be giants, but we stand at their shoulders and can see farther.' An impartial scholarly approach without overstatements to both, Art and the occult is what will best serve our collective development.
Great a seer as he was, Crowley was very much a British Victorian man, of very “Osirian” sensibilities, already a kind of quaint dinosaur compared to our very progressive world. Who knows what the next millennium will bring?
I'm certain that in this Aeon, there will be many brilliant artists, who will find plateaus like Crowley's and Harris' Thoth deck, and use it as a starting point to paintings, and decks more appropriate to the spirit of the future age. That might be a genuine identifying mark of a great occult achievement in the 20th century, though it wouldn't exist without countless other achievements, such as the GD initiation.
