De Codice Arcano · Year of the Forge MMXXVI
The Codex
Arcanum
A library for the forgotten tongues. Nineteen manuscripts in their original scripts, two hundred and eight chapters of curated content, an AI tutor that can read every alphabet the human race has ever written, and a Decoder that can take a photograph of a clay tablet and tell you what it says.
We are not a religious organization, a divination service, or an occult lodge. We are a small team that believed the ancient writings deserved a beautiful home on the modern web. Codex Arcanum is that home.
The Four Pillars
What we built, and why
The Library
208 chapters across 19 codices — Book of Enoch, Agrippa's Three Books of Occult Philosophy, the Picatrix (translated from the 10th-century Arabic by Claude Sonnet 4.5), the Hermetica, the Voynich, Sefer Yetzirah, the Enochian Keys, Liber AL, the Egyptian Book of the Dead, and Keeper's Editions of ten more scripts that lack a clean public-domain English source.
The Decoder
Submit a photograph, a unicode sequence, or a transliteration. The Keeper — backed by Claude Sonnet 4.5 — identifies the script, parses the signs, provides the standard scholarly readings, and translates with honest uncertainty flags. It will tell you what it does not know.
The Tutor
A patient conversational guide to every script in the library. Ask it about the abjad of Phoenicia, the seventy-two names of God, the Maya long count, or the difference between Old Phoenician and Punic. It will answer in the voice of a sympathetic scholar, not a chatbot.
The Forge
Build sigils — historically-attested designs and your own. Goetic Triangle, Solomon's Pentacle, the Tetragrammaton, the Voynich Rosette, the Tree of Life, the Wedjat. Each is rendered cleanly, exportable, and ready to be printed, engraved, or carried.
Signa Recens · The Newest Sigils
Cut from the historical record
Each sigil in the Codex is drawn from a documented historical or scholarly source. We do not invent occult symbols. We render what already exists.
Triangulum Manifestationis
The Goetic Triangle
Lemegeton, Mathers/Crowley 1904. The figure inside which a conjured spirit appears.
Rosa Voynichiana
The Voynich Rosette
Drawn from the famous cosmology page (f86v) of the Voynich Manuscript.
Tetragrammaton
The Four-Letter Name
The Hebrew name of God — YOD HE VAV HE — enthroned in flaming triangle.
Pentaculum Solis
The Solar Pentacle
The pentagram radiant — the most operative sigil of the Solomonic tradition.
Principia · How We Work
Our principles
Principle I
Scholarship over showmanship
Every chapter cites its source. Every translation is attributed. When we do not know something, we say so. When an AI translation marks itself uncertain, we preserve that mark in the rendered text.
Principle II
Public domain first
We seed only public-domain primary texts (Mathers 1889, Charles 1917, Budge 1895, J.F. 1651, Westcott 1887, Dee/Casaubon 1659, Crowley 1904). Where no clean PD source exists for a script, we write our own Keeper's Edition primer rather than scrape copyrighted material.
Principle III
AI as instrument, not authority
Claude Sonnet 4.5 powers the Decoder, the Tutor, and the Picatrix translation. It is an instrument. Its output is reviewed, contextualized, and flagged. Where it gets something wrong, we want to know.
Principle IV
No occult presumption
We make no claim that any of these texts work as ritual instruction. We make no promise of supernatural outcome. We present the material the way Yale or Cambridge presents medieval Latin literature — as cultural artifact, intellectual history, and beautiful object.
Principle V
Privacy as default
We do not sell data. We do not run ads. We do not track you across the web. Sessions are a single httpOnly cookie. Read the Privacy page if you want the details — it is in plain English.
