Elder Futhark
The Elder Futhark is the oldest Germanic runic alphabet, in use from the 2nd to the 8th century AD across Northern Europe — Scandinavia, Germany, Saxon England, the Low Countries. It comprises 24 runes, organised in three groups of eight called ætts (Freyr’s, Hagal’s and Tyr’s), carved on runestones, jewellery, amulets and funerary objects.
It is distinct from the Younger Futhark (16 runes, 9th-11th century, see our Futhark entry) which replaced it during the Viking Age with a simplified version. On CipherChronicle, the Elder Futhark provides 24 glyphs: Latin letters C and V are absent, following Germanic convention (the Kaunan rune ᚲ serves for both K and C, the Uruz rune ᚢ for both U and V). Encryption automatically folds C→K and V→U before rendering.
How does the alphabet work?
The cipher relies on a monoalphabetic substitution: each cleartext letter is replaced by its corresponding rune. The technique itself is ancient (Caesar cipher, ~50 BC); the Elder Futhark was never a secret cipher historically — it was the everyday script of Germanic peoples before they adopted the Latin alphabet.
The table holds 24 runes for the 24 effective letters (Freyr’s ætt ᚠ-ᚹ, Hagal’s ᚺ-ᛊ and Tyr’s ᛏ-ᛟ). The 2 missing Latin letters (C, V) fold onto their historical neighbours (K, U).
Cryptographic strength: low. Like any monoalphabetic substitution, frequency analysis breaks it in a few dozen words. The interest is cultural and historical: an authentic alphabet attested by hundreds of archaeological inscriptions (Kylver stone, Meldorf fibula…).
Historical and modern usage
- Ancient runic inscriptions — 2nd-8th c. across Northern Europe.
- Modern neopaganism — Asatrú, runic divination.
- Viking pop culture — TV (Vikings, The Last Kingdom), games (Skyrim).
- Historical pedagogy — age of Germanic migrations.

What are the weaknesses?
- Monoalphabetic substitution — frequency analysis is immediate.
- Only 24 letters — forced folds C→K, V→U.
- Public alphabet — documented in every Germanic epigraphy handbook.
