Symbolum is an interactive reference for Liber 777, Aleister Crowley's tables of Qabalistic correspondences, first published in 1909 and used by students of Thelema, the Golden Dawn and Hermetic Qabalah for over a century. Tap any sephira or path on the Tree of Life to see everything 777 attributes to it, then tap any entry to see every other place it appears in the tables. --- WHAT'S INSIDE --- All six tables of Liber 777 have been reviewed column by column against the 1909 and 1955 printed editions: the Sephiroth and paths, the elements, the planets, the worlds of the Sephiroth, the signs and decans, the letters and Tarot. Over 1,600 entries, each with its own page. • Angels — the 72 angels of the Shem ha-Mephorash, angels of the signs and decans, planetary and geomantic intelligences • Goetic demons — all 72 spirits by decan, by day and by night • Tarot — the 22 Atu with their secret titles, and all 56 minor arcana with Thoth names, planet in sign, decan angel and perfume • Elements, planets and signs — each with its own page: elemental kings and spirits, worlds, rivers of Eden, parts of the soul, rulers and exaltations • The seven palaces of Briah with their heavens, earths and hells; the Qliphoth and their princes • Gods of many pantheons, colours in the four scales, perfumes, precious stones, plants, animals, legendary beings, magical weapons, powers and formulae • Chakras, skandhas, the Noble Eightfold Path, alchemy and much more --- ALSO INSIDE --- Pentagram and Hexagram — the invoking and banishing forms for each element and planet: where to start and the order of every line, following Liber O (1909). Sepher Sephiroth — Crowley's Liber D (1912): 784 numbers and 2,541 Hebrew words and phrases with their meanings. Number pages show prime, square, factorization and theosophic sum. The Sky — where the planets are right now: positions, aspects, an aspect grid and a live chart of the moment for your place. Scroll through time or press play and watch it move. Planetary hours — the hours of the planets for any day and place, with their angels and names. Your location is used only on the device; you can also pick a city. Alphabets — Hebrew, Greek, Coptic, Arabic and Enochian side by side for every row of the Tree, with a sheet for each letter. --- FREE --- Interactive Tree of Life Every sephira, path and entry page, with cross-references Pentagram and Hexagram with invoking and banishing forms Tatwa meditation Dark, light and automatic themes --- SYMBOLUM PLUS --- Browse — 41 categories of correspondence, from Alchemy to Twelve Tribes, plus Alphabets Search — every name, Hebrew spelling, Crowley's transliteration and translation Liber D — the complete Sepher Sephiroth Bookmarks — save rows and entries for study The Sky — positions, aspects and a live chart, through time Planetary hours — for any day and place Available as an annual auto-renewable subscription or a one-time lifetime purchase.

Tarot titles follow the Thoth deck. Every place where the app departs from the literal print is documented. Alternative attribution systems are outside scope.
