Aleister Crowley ( AL-ist-ər KROH-lee; born Edward Alexander Crowley; 12 October 1875 – 1 December 1947) was an English occultist, ceremonial magician, poet, novelist, mountaineer, and painter. He founded the religion of Thelema, identifying as the prophet entrusted with guiding humanity into the Æon of Horus in the early 20th century. A prolific writer, he published widely over the course of his life. Born to a wealthy family in Royal Leamington Spa, Warwickshire, Crowley rejected his parents' fundamentalist Christian Plymouth Brethren faith to pursue an interest in Western esotericism.
