From this time on I lived in a perfect shower of diplomas, from Bucharest to Salt Lake City.

That is a quote from Aleister Crowley himself, apparently bragging about all his masonic regalia.  The entire article can be viewed here, http://www.the7thfire.com/new_world_order/Freemasonry/aliester_crowley_33_deg..

So--there is supposedly a quote from his own mouth that he was in Salt Lake City.  I have dismissed a connection between Crowley and Lily's inscription, assuming that it was too far-fetched.  But, he was referred to literally & exactly as "The Beast 666".  In that sense, if the inscription does in fact refer to Crowley, it reads well.  Conversely, if it refers to Highway 666, for example, or the actual devil, satan, or a person, one that was cause of abuse in her life, perhaps her husband, as I and others have speculated, there is much that is hidden, and it reads awkwardly.  The idea that there is a figure such as Crowley, referred to exactly as "The Beast 666", and that he was in Salt Lake City, that Lily was the right age to have been a part of his following, all seems to be enough of a lead to pursue.  Please feel free to email me or leave comments with any information you know of concerning Aleister Crowley's time in the U.S., particularly the West & Utah, and anything concerning disciples or students.
