I was able to get a worn copy via interlibrary loan. My one critique with the art was on pages 40-41, where the panels run accross both pages. They could have used a snake to help the reader "slide" down to the next panel. Ladder imagery is used effectively elsewhere, but really the game reference never peaked for me. Otherwise the art helps the reader interpret what would have otherwise been very hard to understand in its spoken form. Taken from a recording, this now sells for 60 dollars used.
It is poetry turned into illuminated manuscript. This is a "comic book" (48 pages) about sex, which is life and death (snakes and ladders?) to Moore. The magic it creates. Still mulling over what "magic" means, but I can see how this might be a stepping stone for the Moon and Serpent Bumper Book of Magic. At one point, Moore says he was visited by his character Constantine. When he's talking about Arthur Machen's "Baghdad" (which I still am trying to wrap my head around as I know little of Machen), I can see where Promethea came from.
