BrightEye,
I don't think this is the one to go with in an academic setting. It's a series of meditations on the Trumps as archetypes, and aims at getting us in touch with the deeper parts of ourselves. (He relies a lot on the anonymous
Meditations on the Tarot, and says as much.) As a collection of meditations, it's very subjective, and doesn't look at the symbolism of the cards in a historical or academic way.
At one point, this leads to a massive howler. There's a tradition in Marseille decks that the artist's initials appear on the shield on the front of the chariot on the trump card of that name. That custom wasn't and isn't universal. Sometimes that shield is blank, sometimes we don't know for sure what the letters refer to. On the Grimaud deck by Mr. Marteau (the deck used in
Tarot, Talisman or Taboo), the letters are SM, and you can find some speculation about possible meanings of these letters in posts here at AT.
Hederman's reflections on that detail are that "The SM emblazoned on the front describes the opposites that need to be combined, a symbiosis of conflicting needs required to harness creatively the turbulent violence of instinctual nature. Domination is not the answer; nor is craven submission. Discipline comes from harmonious involvement in appropriate and spontaneous activity." I think that's good advice. But this really does take the letters on the shield to be S/M, in the sense of kinky sex.
This might make an amusing footnote in your paper. But I'm really, really sure that's not what the designer of the card had in mind. For an academic work, you probably ought to look at some source that's more historical research and less inspirational meditation.
I'm trying to write something on Tarot in literature,
There is a chapter in the book called "Yeats, Tarot, and the Golden Dawn." But it didn't have enough detail and facts to satisfy my desire to learn more about Yeats and the cards, and may not have enough to be useful to you.
I don't have much of a Tarot library, but two books I do have that look at the symbolism of the trumps in a historical context are Huson's
Mystical Origins of the Tarot and Place's
The Tarot: History, Symbolism, and Divination.
Hope I haven't soured the milk too much. Good luck with your paper!
