Both volumes of Moncure Daniel Conway's excellent treatise on demons and devilry are presented here complete. Written in the 19th century, this lengthy and thorough text documents the various manifestations of demons and devils in the Christian religion. The forms they take, and the means by which they appear in the physical world, are cataloged. How they correspond to actual phenomena, such as death and pestilence, is likewise noted. Conway draws upon various writings within the Biblical scriptures, together with later works published in the Middle Ages and subsequent centuries, to arrive at his own comprehensive treatment of the subject. The second volume of the work concerns devils. Various figures such as Ahriman and Visw mitra receive chapters, in which the writings about them are quoted to form a complete image of their behavior and meanings. Appearances of devils in later works, such as the diabolical Mephistopheles in Goethe's Faust, are also cataloged.

The Book of Black Magic is Arthur Edward Waite's magnum opus of occult lore; this edition contains the author's original icons, symbols, seals and drawings.

Here, Waite examines the ritualistic traditions which surrounding the occult movement for centuries. He notes various texts, and how these had a bearing upon the practice of the occult and of magical ceremony. The second part, ""The Complete Grimoire,"" concerns how those who practice black magic and occult ritual become versed in the craft. The stringent physical and mental requirements, and the need to practice a spiritual attunement and inner ablution, is detailed. Astronomical knowledge of the planets and their movements is a necessity, as is possession of a variety of instruments, plus a deep knowledge of the various symbols and scripts used in occultism.

The Book of the Law, the holy text that forms the basis of Thelema, was transmitted to Crowley by the entity known as Aiwass in Cairo, on three successive days during April 1904. Acting as a medium, Crowley recorded the communications on hotel notepads and later organized his automatic writing into a short, coherent document. Aiwass/Crowley presents The Book of the Law as an expression of three god-forms in three chapters: Nuit, Hadit, and Ra-Hoor-Khuit.
