Who is Choronzon?

"Choronzon (Coronzon) is a Demon or spirit identified in the 16th century by John Dee and Edward Kelly, summoned in a dramatic ritual by Aleister Crowley in 1909. Dee referred to “Coronzon,” or 333, in his Enochian communications with spirits; he did not consider it to be a Demon. Crowley called Choronzon the Demon of Dispersions and of the Abyss."

"Choronzon first appeared in the Enochian writings of John Dee in the 16th century, where he was synonymous with the serpent in the Garden of Eden. Aleister Crowley paraphrased Dee's description of Choronzon as "the first and deadliest of all the powers of evil...rightly so, for although he is not a person, he is the metaphysical contrary of the whole Process of Magick" (1998). In the system of Thelema, Choronzon is the Dweller in the Abyss, that great spiritual wilderness which must be crossed by the adept to attain mastery. Choronzon is there as the final obstruction. If he is met with the proper preparation, then he is there to destroy the ego, which allows the adept to move beyond the Abyss. If unprepared, then the unfortunate traveller will be utterly dispersed into annihilation."

"Crowley states that he and Victor Benjamin Neuburg evoked Choronzon in the Sahara Desert in December 1909. In Crowley's account, it is unclear whether Choronzon was invoked into an empty Solomonic triangle while Crowley sat elsewhere, or whether Crowley himself was the medium into which the demon was evoked. Nearly all writers except Lawrence Sutin take him to mean the latter."

"Choronzon is a spirit of dissolution, physical, mental and spiritual. Everything around it will begin to decay. It will do its best to hasten the dissolution of everything it can reach. Matter will slowly dissolve. Living beings will age and sicken. It derails the trains of thought, and turns people insane. In the vicinity of it, nothing remains untainted."
