Another Option
I've also had Gerd Ziegler's "Tarot: Mirror of the Soul" (subtitled Handbook for the Aleister Crowley Tarot) since 1988 but haven't spent much time with it. To help respond, I just dipped into it and did a few quick comparisons to BoT. At that cursory level I didn't find much to quibble with, except that the language is (probably intentionally) more pedestrian than Crowley's well-tooled turn of phrase. It seems to have more fleshed-out and consistent descriptions for the "small cards" but it dispenses with many of the qabalistic, astrological and mystical elaborations in the text itself and loses some of AC's legendary obscurantism (and attitude) at the same time. The descriptions aren't "bad," they just seem a bit vanilla ("milk for babes" rather than "strong meat for men"?) On the face of it, I'm not sure it adds much to a thorough understanding of the deck, but I kind of like some of the touches. The Indications and Affirmations read like aphorisms (ala Sturzaker and Case) and as a fan of the Wilhelm translation of the I Ching I'm kind of a sucker for those. It looks to me like a sanitized version of Crowley that won't frighten or befuddle old ladies and children, while still keeping enough of the essence to make it recognizable. Frankly, except possibly as a window into how the general populace can swallow their Crowley and keep on smiling, I'm not quite sure what I would use it for. But maybe I just need more time with it.
