Liber 777 is almost entirely tables. Its core is a set of numbered columns in which every row corresponds to a position on the Tree of Life, one of the ten sefirot or one of the twenty two paths, and each column supplies what that position corresponds to in some other system: the Hebrew letter, the tarot trump, the planet or sign, the element, the colour in four scales, the perfume, the plant, the precious stone, the animal, the Egyptian god, the Greek god, the Hindu deity, the magical weapon.
The columns of Egyptian, Greek, Roman, Hindu, Buddhist and Chinese material are Crowley's principal addition to what he received. The Golden Dawn's own book of correspondences supplied the Western spine; he extended it eastward, and the extension is both the work's value and its main problem, since placing a deity from one tradition in a column beside a deity from another asserts an equivalence the traditions themselves do not make.
The format is the argument. A table implies that its rows are commensurable, and a reader who accepts the table has accepted the claim that all these systems are versions of one. The atlas records the correspondences as this tradition's own and does not treat them as facts about the traditions drawn on.
