"Glory unto the Scarlet Woman, Babylon the Mother of Abominations, that rideth upon the Beast, for she hath spilt their blood in every corner of the earth, and lo! she hath mingled it in the cup of her whoredom."
(He didn't yet have the correct spelling of "Babalon.") He is mentioned in the same aethyr as "the crowned beast" that she rides. And then a powerful statement:"
"And the Beast whereon she rideth is the Lord of the City of the Pyramids."
Actually, there is evidence Crowley was aware of, and used the spelling Babalon five years before the work documented in The Vision & The Voice.
In the notebook titled Invocation of Hoor, which was started while in Cairo in the spring of 1904, a 36 card Tarot spread dealt in the summer of 1904 ends the notebook; in the written interpretation of the cards, Crowley associates the 2 of cups with** Babalon**, and also uses the term City of the Pyramids in the interpretation of another card: both terms are featured prominently in the The Vision & The Voice as shown in your previous post.
