Alphabet of the Magi
The Alphabet of the Magi (Latin alphabetum magorum) is one of three “secret” alphabets published by Paracelsus in the 16th century in his alchemical corpus, alongside Malachim and Passing the River. It was widely diffused across Europe by Francis Barrett in The Magus, or Celestial Intelligencer (1801), the reference work of the Anglo-Saxon occult revival, under the name Magi alphabet of Raphaël (after the archangel Raphael, the heavenly scribe).
Like the Celestial and Malachim, it is a Hebrew-derived alphabet: 20 mother letters cover the 26 Latin letters, at the cost of a few phonetic folds.
How does the Alphabet of the Magi work?
The cipher uses a monoalphabetic substitution: every letter of the plaintext is replaced by a glyph drawn from a fixed correspondence table. It is one of the oldest cryptographic techniques on record — already described in antiquity (Caesar cipher, ~50 BC) — and the most directly readable family for a beginner.
The table holds 20 glyphs for the 26 Latin letters (no dedicated digit glyphs). To encrypt, read the text letter by letter and replace each letter with its glyph; to decrypt, consult the same table the other way round.
A few Latin letters fold phonetically onto others: C→G, J→I, F→V, U→V, W→V, Y→V. They have no dedicated glyph and are substituted before encryption, narrowing the effective alphabet to 20 distinct graphemes.
Cryptographic strength: weak. Because every plaintext letter always maps to the same glyph, the cipher falls to a frequency analysis in a few dozen words (in both English and French, E remains the most common letter, an immediate entry point). Monoalphabetic substitutions are therefore used today for their decorative, playful or pedagogical value — not to protect real information.
Historical and modern usage
- Paracelsus (16th c.) — alchemical corpus, alphabet used to sign or encrypt secret recipes.
- Francis Barrett, The Magus (1801) — reprinted in the great occult synthesis that inspired the Golden Dawn, Aleister Crowley and the entire 19th-century Anglophone magical tradition.
- Modern ceremonial magic — used in initiatory orders and chaos magic.
Related variants
- Celestial — Agrippa’s other alphabet, same mother letters but folds G→C, P→F, Y→I.
- Malachim — angular variant of Celestial.
- Enochian — Dee/Kelley’s alphabet (1583).
What are the weaknesses of the Alphabet of the Magi?
- Monoalphabetic substitution — falls immediately to frequency analysis.
- Public alphabet: reproduced in every occultism treatise.
- Six letters fold onto four glyphs (Vav, Yod, Gimel) — round-trip information loss for messages containing C/F/J/U/W/Y.
