777 and Other Qabalistic Writings of Aleister Crowley
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 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.
The tables were constantly revised in Crowley's lifetime but it was not until 1955 that they were published ("Revised Prolegomena Symbolica ad Systemam……"). This includes smaller tables that extrapolate correspondences of the five elements, twelve zodiacal signs and seven planets only.
