Liber 777

777 is one of the most prominent books of the Qabalah in the western esoteric tradition, alongside Samuel Liddell MacGregor Mathers' Kabbalah Unveiled, Israel Regardie's A Garden of Pomegranates and Dion Fortune's Mystical Qabalah. The Kabbalah however is a much earlier Jewish form of Torah commentary that was prominent in the sixteenth century via the book the Zohar. It introduced the diminishing Four Worlds, God as the transcendent Ain Soph, Israel as embodying the Shekinah, or "presence", as spouse of the male God, and most popularly the ten Sephiroth as schema of the universe between Israel and Jehovah. It did this by interpreting the concrete letters of the scripture rather than, say, the universal parable more evident in the gospels. Through the reformation it became popular with occultists like Heinrich Cornelius Agrippa, Pico della Mirandola and Eliphas Levi before being formalised in popular new-age magic.

Gematria was extrapolated from The Equinox vol. 1, no.5 where it was originally titled Temple of Solomon the King continued being the fifth in that series. It explains the dogmatic Qabalah as taught by the original order of the Hermetic Order of the Golden Dawn. The main studies are the ten sephiroth - emanations or rungs of a divine hierarchy between Earth and Godhead - and the three forms of word analysis. These consist of gematria where each of the twenty-two letters of the Hebrew alphabet have their own number and are added together in words to make metaphorical sympathy; aiq baqir, also called "Qabalah of the Nine Chambers", which converts any letter in a word to its radical equivalent. It quotes much of the introduction to Mathers' Kabbalah Unveiled and also Crowley's own Qabalistic Dogma, an appendix to his Collected Works vol. I. before beginning a study of important numbers in magical art.

Liber 777 Vel Prolegoma Symbolica Ad Systemam Sceptico-Mysticae Viae Explicande, Fundamentum Hieroglyphicum Sanctissimorum Scientiae Summae is designated a "Class B" document by Crowley. The title refers to a lightning flash descending the diagrammatic worlds, the zig-zag pattern suggesting three diminishing 7s. It consists of roughly 191 columns, with each row corresponding to a specific Sephirah or path on the Tree of Life for a total of 35 rows and is used for a quick reference for corresponding mnemonics and factors of religion for use in magic (for instance, an evocation of Venus would have one looking across that column for the colour corresponding to Venus that will be the colour of his or her robe, and then Venusian incense, etc.).

The first appearance of 777 was published anonymously in 1909 after Crowley had written it from memory in just a week. An introduction to one edition by "Frater N∴" states that Crowley may have published it anonymously because it was taken from a Hermetic Order of the Golden Dawn manuscript that was obligatory for initiates to memorise.

Within the detail of the book the column's vertical axis is numbered from 1 to 32 signifying the 32-paths of wisdom which occur in the western Qabalah, numbers 1 - 10 are the sephirah of the universe and numbers 11 - 32 the paths which join them. The horizontal columns have many categories pertinent to religion, mythology and magick given in some 32-parts each. The Hebrew alphabet, the Tarot cards and the astrological glyphs fortunately total 22-each and are given to the paths as a map of the magician's universe. From the 11th path onward some of these numbers have been exemplified by appearing to the left or right in the margin for easy reference, paths 11, 23, 31, 32-bis and 31-bis are leftwards and denote the five astrological elements; paths 15, 16, 17, 18, 19, 20, 22, 24, 25, 26, 28, 29 are rightwards and denote the 12 astrological signs, the rest are astrological planets.
