Also known as : Younger Futhark · Scandinavian runes · runic alphabet

Futhark is the Germanic runic alphabet, named after its first six runes: F, U, Þ (th), A, R, K. It exists in two main variants:

  • Elder Futhark (2nd-8th c.) — 24 runes, used on stones, weapons and jewelry of early Germanic Europe.
  • Younger Futhark (8th-12th c.) — 16 runes, simplified by the Vikings for quick carving. Several Latin letters share a single rune (C/K, O/A, D/T…).

Principle

A 1:1 monoalphabetic substitution (or close to it — in Younger Futhark some runes cover two sounds). Each Latin letter maps to a specific rune.

Younger Futhark (16 runes) excerpt:

ᚠ = F            ᚱ = R            ᛏ = T/D
ᚢ = U/V/W/O      ᚴ = C/K/G        ᛒ = B/P
ᚦ = Þ (th)       ᚼ = H            ᛘ = M
ᚬ = A/O/Æ        ᚾ = N            ᛚ = L
                 ᛁ = I/E/J        ᛦ = R (final)
                 ᛅ = Y/Æ          ᛋ = S

Each rune uses straight strokes only — a legacy of carving on wood, bone, stone, where curves were awkward along wood grain.

Historical origin and use

  • Scandinavian runestones (Viking Age, 800-1100) — memorial inscriptions, hero signatures, territorial markers.
  • Amulets and talismans — runes carved on wood or metal, worn for protection or luck.
  • Runic calendars — carved sticks used as agricultural almanacs.
  • Weapon inscriptions — owner names, warrior exaltations.

Runes are fundamentally a script, not a cipher. But they have been used as a concealment alphabet since the Renaissance: hiding a Latin message by writing it in runes. They were also revived by Hitler for pan-Germanic propaganda — a usage that should be kept at arm’s length.

Variants

  • Elder Futhark (24 runes) — original, fuller version.
  • Anglo-Saxon Futhorc — English extension to 33 runes (until the 7th century).
  • Younger Futhark — 16-rune Viking simplification.
  • Medieval Dalecarlian — runic survival in Dalarna (Sweden) up to the 19th century.

Weaknesses

As a cipher:

  • Monoalphabetic substitution — yields to frequency analysis.
  • Public alphabet: available in any runology or fantasy handbook.
  • Linguistic ambiguity in Younger Futhark (one rune = several Latin sounds) can confuse decoding but offers no protection.
