Aleister Crowley was an English occultist, ceremonial magician, poet, novelist, mountaineer, and painter. As the founder of the religion of Thelema in the early 20th century, he identified as its prophet, entrusted with guiding humanity into the Æon of Horus. A prolific writer, he published widely—composing the "Libri" of Thelema—over the course of his life.
In September he went to Lisbon in Portugal to meet the poet Fernando Pessoa. There, he decided to fake his own death, doing so with Pessoa's help at the Boca do Inferno rock formation.[179] He then returned to Berlin, where he reappeared three weeks later at the opening of his art exhibition at the Gallery Neumann-Nierendor
