Aleister Crowley crafted Liber DCLXXI vel Pyramidos from an earlier ritual he called the ThROA or LIber 671. Both rituals are based on the Neophyte Ceremony of the Hermetic Order of the Golden Dawn. While the ThoROA ritual was meant to be conducted by several officers with a candidate, Pyramidos would be simplified even more to ensure it could be performed by a single person and would become one of the rituals of self initiation used within Crowley's A∴A∴ even though it was never truly published. While self initiation was the main goal of the ritual, Crowley also designed so that it could be broken down into parts and used in other rituals and formats as well. So presented here in an affordable paperback copy meant to be bent, written in, used and abused is Liber DCLXXI vel Pyramidos: A Ritual of Self Initiation based upon the Formula of the Neophyte along with Journal Pages attached in the back of the book to make note taking that much easier. We've also included the Neophye Ritual of the Hermetic Order of the Golden Dawn to better assist the student in the understanding of Pyramidos. It is the hope of the Editors here at Bounty of Babalon Publishing that any aspirant to the A∴A∴ may now have access to this important and powerful ritual.
