Liber Null, illustrated by Andrew David, and Psychonaut, with same by Brian Ward, are two separate books. The first is again divided into Libri MMM, LUX, NOX et AOM, and in these books Pope Pete deals with gnosis, divination, evocation, enchantment, sigils and "random belief," something that really amused me. Psychonaut is a collection of fascinating essays on, inter alia, new aeon magic, the rites of chaos, chemognosis (with a particularly interesting discussion of hallucinogens like the amanita and psylocybe mushrooms and the solanum species), shamanism, gnosticism, magical paradigms and magical time. My only problem is the - to say the least - disturbing illustrations by Ward. To someone with a sensitive disposition, these detract somewhat from the pleasuree of the reading experience. The text is richly enlivened by diagrams, figures, glyphs and perhaps to its detriment, by those eerie pictures. Apart from that, it's a no-nonsense magical handbook in a lucid and engaging style. A classic of sorts, I guess. Heartily recommended to fans of "The Addams Family" movies.
