  • Reconstructed Proto-Germanic name for the s-rune
  • Derived from Old Italic and Greek sigma shapes
  • Known as Sigel in Old English and Sól in Old Norse
  • Adopted by the Nazi SS as the double lightning bolt emblem
  • Attested in all three surviving Rune Poems

What it is

Sowilo stands as the reconstructed Proto-Germanic designation for the rune representing the sound s. This character forms a core part of several ancient Germanic alphabets. It serves as a linguistic marker for the sun within these writing traditions. The symbol connects directly to concepts of solar power and celestial light. Scholars identify it through its consistent presence in early runic texts.

Where it comes from

The letter originated from Old Italic scripts, specifically adopting the form of the Latin or Etruscan s. This shape traces back even further to the Greek sigma. Early examples appear on artifacts dating to the second and third centuries. Sites like Vimose and Kovel provide some of the oldest known inscriptions featuring this character.

How it is done

The rune evolved through distinct visual phases. Early versions used a four-stroke sigma shape common in the third to fifth centuries. Later iterations shifted to a three-stroke s-shape prevalent in the fifth to seventh centuries. The Anglo-Saxon tradition developed a unique bookhand variant inspired by Insular script long s forms.

Tools and materials

Inscriptions on bone, wood, and metal serve as the primary carriers of this symbol. The Vimose finds and the Spearhead of Kovel represent early material evidence. Later stone monuments like the Kylver stone display the older sigma variant. Metalwork such as the Golden horns of Gallehus showcases the later angular style.

What it is for

The rune functions primarily as a phonetic sign within written language. Its name preserves the ancient concept of the sun. It acts as a cultural link to Germanic cosmology. The symbol also gained modern political weight when adapted into Nazi emblems, though this diverges from its original linguistic purpose.

Who does it

Historians and linguists study the rune to understand Germanic language development. They analyze variations across different regional scripts. Researchers examine how the symbol transitioned from Italic origins to native Germanic forms. Modern occultists have appropriated the shape for symbolic purposes unrelated to historical usage.

Peoples and places

The rune belongs to the broader Germanic cultural sphere. It appears in Old English texts under the name Sigel. Old Norse and Old Icelandic sources refer to it as Sól. All three major Rune Poems attest to its use across these diverse linguistic groups. The symbol bridges the gap between continental and insular Germanic traditions.

At a glance: who, where and when

What people believe

The name Sowilo reflects an archaic Indo-European alternation pattern related to the sun. This linguistic feature persists in various ancient languages including Avestan and Sanskrit. The Germanic words for sun show a split between l-stem and n-stem variants. The rune captures one side of this complex etymological history.

How scholars and sceptics see it

Linguists trace the rune's path from Greek sigma through Old Italic scripts. They debate the exact pronunciation and semantic nuances in early periods. Some suggest alternative derivations for the Old English name Sigel. Research continues into how the symbol functioned within daily communication versus ritual contexts.

Cautions and what is closed

The symbol was heavily co-opted by the Nazi SS in the twentieth century. Guido von List created a modified version called the Armanen sig rune. Walter Heck adapted this design into the double lightning bolt emblem adopted by all SS branches in 1933. This association carries significant negative historical baggage.

Compare and confuse

The rune differs from other letters in its specific solar association. While many runes represent natural forces, Sowilo explicitly names the sun. It contrasts with the Lindholm amulet inscription Sawilagaz which means the one of the sun. The shape also resembles the modern Opel logo, though this is a coincidence of design.

Today

The rune remains a subject of academic interest in historical linguistics. Its image persists in popular culture due to its striking geometric simplicity. The Nazi appropriation ensures that its use requires careful contextual awareness. Modern practitioners often study it as part of broader runic education.
