This is a compilation of two separate books published in the late 90's by Logos Press. NOX: The Black Book Vol 1 (I don't think there was ever a Vol II) contains a wide range of articles from various nefarious occult writers varying in quality from the ridiculous to the sublime. The first few essays are from the Order of the Nine Angles which claims to be the only true form of "Traditional Satanism" tracing its origins back to Albion. Unfortunately, it is far more likely it was created by David Myatt (See Black Sun by Goodrick-Clark) as a forum and recruiting cult for his ideas and is a hodge podge of various themes taken from Crowley, Spengler, traditional Gregorian chants turned bad, culling, and national socialism. There are a few interesting ideas but as with most things in occultism- buyer beware! The next essays are on the Werewolf Order which I found very sophomoric with your normal left hand path elitist nonsense. There are some interesting and groundbreaking groups and ideas out there in lycanthropy as a magickal discipline but this ain't it. I am glad to see that Nikolas Schreck has moved on from this to publish the excellent Demons of the Flesh and found with his partner, Zeena Lavey, the LHP tantric occult group called The Storm. The last part of this book is a collection of essays under the heading of The Nameless Sodality. Michael Bertiaux has a short essay on his incomprehensible path of voodoo. The next are a mixture of Lovecraftian rituals and essays by different authors ranging in quality. The one gem in the collection is the very lucid entry by Phil Hine on vampirism.
The best portion of the book is Liber Koth by Stephen Sennitt. He includes a nice introductory essay on Lovecraftian magick in which follows his personal sigils and experiences with the Mythos pantheon (Yog-Sothoth, Kadath, Hastur, Nyarlathotep, Cthulhu, Tsathogua, Shub-Niggurath, and Azathoh). As it should be with this form of magick, Sennitt merely gives impressions and images of his own pathworking and rites without ruining it with a bunch of explanations.
This compilation does reflect, in my opinion, most of the left hand path ideas and groups out there expressing everything from creative brilliance to downright juvenile nonsense. These essays can put one in the right state of mind for personal inspiration, and as a person observed about the left hand path long ago that "the texts of another is an affront to the self."
