Aleister Crowley, an English poet and occultist whose life blended high‑brow literary pursuits with radical mysticism, is explored in this biography.

"Aleister Crowley (1875-1947) was a visionary occultist, a member of the theosophical order of the Golden Dawn. Nicknamed 'The Beast', he was vehemently anti-Christian, and supported the use of drugs and sexual magic as a means to access deeper levels of consciousness. For 100 years his true achievements have been suppressed, his true character deformed and defaced in a campaign of vilification unparalleled in British history. Here is the world's first complete, thoroughly researched biography of Aleister Crowley, demolishing the myths, establishing the facts and telling with verve and style the astonishing and exciting story of his life, including many 'missing years', intrigues, discoveries and adventures - all revealed and explained for the first time. Crowley's grandson has provided exclusive access to crucial information about his family relationships, and there is a compelling account too of his work as a British spy during World Wars I and II."--Publisher's website.

From back cover: This unique biography tells the story of an extraordinary fifteenth-century woman who journeyed all over Europe from England to the Holy Land. A vigorous and passionate woman, Margery Kempe was married and had fourteen children when she deserted her family to make a pilgrimage to Jerusalem to expiate a "secret sin" in her early life. Along the way she meets many famous prelates and dignitaries, gets into all sorts of scrapes, and survives a feverish voyage in the stinking galleys of a Venetian boat. Drawing on the chronicles of her contemporaries and on her own clear-eyed autobiography -- dictated to a priest near the end of her life and said to be the first written in English -- these memoirs reveal a woman who has strange ideas about such things as sin and sainthood, dress, diet, and sex, and provides a colorful and detailed picture of everyday medieval life in England and around the rim of the Mediterranean. Part-time historian Louise Collis brings a novelist's flair to this fascinating, well-researched story.

"This definitive work on the occult's 'great beast' traces the arc of his controversial life and influence on rock-and-roll giants, from the Rolling Stones to Led Zeppelin to Black Sabbath. When Aleister Crowley died in 1947, he was not an obvious contender for the most enduring pop-culture figure of the next century. But twenty years later, Crowley's name and image were everywhere. The Beatles put him on the cover of Sgt. Pepper's Lonely Hearts Club Band. The Rolling Stones were briefly serious devotees. Today, his visage hangs in goth clubs, occult temples, and college dorm rooms, and his methods of ceremonial magick animate the passions of myriad occultists and spiritual seekers. Aleister Crowley is more than just a biography of this compelling, controversial, and divisive figure--it's also a portrait of his unparalleled influence on modern pop culture"--
