Ballet Alphabet
The Ballet Alphabet is a steganographic writing system where each Latin letter is represented by a silhouette of a classical-ballet dancer in a characteristic pose. Arm positions (1st, 2nd, 3rd, 4th, 5th), leg positions (pliés, dégagés, arabesques, attitudes) and head positions combine into a visual code readable as a choreography.
The exact origin is obscure — the alphabet circulates in amateur puzzle anthologies of the late 20th century (Dover puzzle books, Detective Academy, La Chasse au trésor) without clear authorship. It is occasionally used in dance-themed escape rooms, gala invitations or season programmes of ballet companies (in a decorative role).
An encrypted message looks like a choreographic frieze — a row of dancers in mid-performance — making it an excellent vehicle to hide text in an artistic context.
How does the alphabet 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 26 glyphs for the 26 Latin letters + 9 silhouettes for digits 1 to 9 (no 0). Each glyph is a classical-ballet dancer silhouette in a characteristic pose: arm positions (1st, 2nd, 3rd, 4th, 5th), leg positions (pliés, dégagés, arabesques) and head positions.
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
- Puzzle anthologies — Dover puzzle books, Detective Academy, La Chasse au trésor.
- Themed escape rooms — on dance, art or music.
- Ballet programmes — occasional decorative use.
- Pedagogy — a good example of cultural visual steganography.

What are the weaknesses?
- Monoalphabetic substitution — immediate frequency analysis.
- Drawing variations — each edition can redraw the silhouettes differently.
- Incomplete digit coverage — no 0, only 1-9.
