Rune: Sowilo — Elder Futhark position: 16 — Sound value: S
The Rune of the Sun
Sowilo is the sun. Not a symbol of the sun, not a metaphor — in the Norse runic tradition, this rune is the sun itself, compressed into a single angular stroke. Its shape is a lightning-bolt S, a form that suggests speed, energy, and light cutting through darkness at an angle. When you trace Sowilo, you are drawing the path of something that does not stop, does not rest, does not turn aside.
In Norse mythology, the sun is not a god but a goddess. Sól (also called Sunna) drives her chariot across the sky each day, pursued by the wolf Sköll who will catch her at Ragnarök. The pursuit never ends until it ends everything. The sun in Norse thought is not a comfortable, permanent fixture — it is something earned and re-earned every day, something moving urgently because standing still means being caught.
Sowilo holds all of that inside it. Light, yes. But also urgency. Also effort. Also the understanding that even the most fundamental things in existence are in motion.
What Sowilo Means
Sowilo is one of the most consistently positive runes in the Elder Futhark. Its core meanings cover:
The sun and its energy. Warmth, light, vitality, the life force that drives growth. After the long darkness of Hagalaz, Naudhiz, Isa, and the other runes of the second aett, Sowilo is the light that breaks through. In the northern climate where this tradition developed, sunlight was not taken for granted — it was something celebrated, marked, honoured.
Victory. The Old Norse rune poem connects Sowilo directly to victory: “Sol is the light of the land; I bow to the holy doom.” Elsewhere, in the poem Sigrdrifumál, the valkyrie Sigrdífa instructs the hero Sigurd to carve sun runes on the blades of his weapons if he wants victory in battle. Sowilo is not passive good luck — it is the energised force that overcomes opposition.
Wholeness and completion. The sun completes its circuit. It rises, crosses the sky, and sets, and then rises again. Sowilo is associated with cycles that fulfil themselves, with wholeness achieved rather than imagined.
Clarity and revelation. Where sunlight falls, things become visible. Sowilo is the rune of seeing clearly, of having things illuminated that were previously in shadow. This is both literal (the sun reveals the landscape) and metaphorical (understanding arrives like light).
Sowilo in the Rune Poems
Three main rune poems survive from the Norse and Germanic traditions: the Old Norse, Old English, and Old Icelandic. All three address Sowilo, and all three position it as fundamentally positive.
The Old English poem describes the sun as “the hope of seafarers when they journey across the fish's bath.” For a maritime culture navigating by celestial landmarks, the sun was not merely pleasant — it was a navigation point, a guarantee of orientation when everything else was uncertain. Sowilo tells you where you are.
The Old Icelandic poem calls the sun the shield of the clouds, the shining glory, the destroyer of ice. Each of these descriptions emphasises the same quality: the sun as the thing that overcomes. Ice melts. Clouds part. The glare defeats the darkness.
A Difficult History to Address Honestly
Sowilo is one of the runes that modern people sometimes hesitate over because of its association with the doubled SS insignia used by the Schutzstaffel in Nazi Germany. The doubled Sowilo rune was chosen for the 1930s, almost certainly because of the association with lightning and aggression — an appropriation, not an origin.
It is worth being clear about this: Sowilo is thousands of years older than the twentieth century, and its Norse and Germanic meaning has nothing to do with the political appropriation of the 1930s. Victory, the sun, life force, clarity — these are its actual meanings, and they were its meanings for the entire span of runic tradition before that appropriation occurred.
This does not mean the history should be ignored. It means it should be understood and then placed accurately: the SS chose to misuse a rune for reasons of intimidation and aesthetic. That choice is the SS's history, not the rune's. Sowilo was used by Norse and Germanic peoples for protection, victory, and navigation for a very long time before anyone had the idea of putting it on a uniform.
Working with Sowilo
Sowilo is engaged when you need energy, clarity, or forward momentum. Its solar quality makes it useful in:
Victory and success intentions — particularly for endeavours that require sustained effort rather than a single moment of force. The sun does not conquer darkness with one burst; it rises and crosses the whole sky.
Clarity and decision-making — when you need to see something clearly, when shadows of uncertainty are making it hard to move forward, Sowilo brings the light that reveals.
Recovery and vitality — after difficulty, cold, or depletion, Sowilo is the rune of return. The sun comes back. The ice melts. This too shall not last.
Merkstave (reversed): false hope, clouded judgment, things that appear positive but are not what they seem. The light that flatters rather than reveals.
Sowilo in the Elder Futhark Series
Sowilo follows Algiz — the rune of protection and divine connection — and precedes Tíwaz, the rune of Tyr and sacred sacrifice. After the outward reach of Algiz calls on divine protection, Sowilo arrives as the answering force — the light and energy that protection makes possible. Then Tíwaz asks what you will pay for what you value. Together the three form a movement from reaching to receiving to choosing.
