Ullr, Norse god of the bow, skis and oaths

Who is Ullr?

Ullr is the Norse god of the bow, of skis and of the duel. He is the son of the goddess Sif and the stepson of Thor, and he lives at Ydalir, the “yew dales” — yew being the wood a bow is made from.

What sets him apart is a silence: no surviving myth has him in it. Thor has dozens of adventures, Loki hundreds of lines; Ullr has descriptions, poetic epithets and a ring people swore on. Yet his name is written all over the map of Norway and Sweden. He is the textbook example of a god whose cult outlived his stories.

Sif’s son, Thor’s stepson

Snorri compresses the whole portrait into a few lines of Gylfaginning: Ullr is “the son of Sif, stepson of Thor”, such a good archer and skier that no one can match him, handsome, with every accomplishment of a warrior — “and he is good to call upon in single combat”.

The genealogy is the revealing part. Norse tradition nearly always names a god through the father: Thor is Odin’s son, Freyr and Freyja are the children of Njord. Ullr is anchored only to his mother, and no source supplies a father. Because Sif married Thor, Ullr belongs to the thunder god’s household by marriage rather than by blood.

That anomaly is one of the strongest arguments for his antiquity: a god who was already there, and had to be attached somehow to the Aesir family tree once it settled into its written form.

Ydalir, the bow and “Ullr’s ship”

Grímnismál runs through the halls of the gods and gives Ullr the fifth: Ydalir, literally “yew dales”. The name is a disguised attribute — Old Norse ýr means both the yew tree and, in poetry, the bow itself. Housing Ullr in yew dales houses him inside his own weapon.

Skaldic kennings fill in the rest. He is öndurás, “ski-god”, bogaáss, “bow-god”, and the god of the shield. Run the other way, the same convention makes the shield “Ullr’s ship” (Ullar skip). No surviving text explains that image, which implies a lost myth in which the god crossed water on his shield, using it as a sledge or a small boat.

The overlap with Skadi, the other skiing, bow-hunting deity, is hard to miss, and probably meaningful: Norse mythology preserves two winter figures with nearly the same equipment — one a giantess absorbed into the Aesir, the other an Aesir god with no known father.

The ring of Ullr: a god of law

The single most suggestive line comes from Atlakviða, one of the oldest heroic poems in the Poetic Edda, where oaths are sworn “on Ullr’s ring” (at hringi Ullar).

The oath ring was a real Scandinavian institution: a ring kept at the sanctuary, on which binding promises were made at assemblies. That it carries Ullr’s name means he was not merely a hunter but a guarantor of the sworn word, a god attached to legal procedure — which fits Snorri’s note about calling on him in the einvígi, the judicial duel used to settle disputes before it was outlawed in Iceland.

Grímnismál adds a stanza nobody has fully decoded: whoever first reaches through the flames of the hearth wins “the favour of Ullr and of all the gods”. Whatever ritual stands behind it, the formula confirms that Ullr was a name people invoked, not just a character in a tale.

Ollerus in Saxo: the stand-in ruler

One late and strange variant survives in the Danish chronicler Saxo Grammaticus (Gesta Danorum, Book III, c. 1200). Under the Latin name Ollerus, Ullr appears when Odin, disgraced, is stripped of his sovereignty for ten years: the gods put Ollerus on the throne in his place, and he even takes the name Odin. When the rightful ruler returns, Ollerus flees to Sweden and is killed there.

Saxo supplies one priceless detail: Ollerus crossed the seas on a bone carved with spells, as fast as by oar. It is the only narrative echo of the “Ullr’s ship” kenning anywhere in the record — which is why many commentators read that bone as the shield, or the ski, of a tradition otherwise lost.

Saxo has to be read for what he is, though: a Christian author who euhemerises the gods into human kings and sorcerers. His Ollerus documents twelfth-century Danish learned memory, not living pagan belief.

The god the myths mislaid

Outside the texts, Ullr is everywhere. His name forms an unusually large set of cult place names in eastern Norway and Sweden: Ullensaker and Ullevål in Norway, Ultuna and Ullevi in Sweden, built with the elements typical of worship sites (-vé, “sanctuary”, -akr, “field”, -tún, “enclosure”). A variant of the name, Ullinn, turns up in other Norwegian names, suggesting regional forms of the same god.

Older still, the Thorsberg chape — a scabbard fitting recovered from a bog in Schleswig and dated to around 200 CE — carries the runic inscription owlþuþewaz, read as “servant of Wulþuz”. If that Wulþuz is the linguistic ancestor of Ullr, the name predates the Icelandic Eddas by roughly a thousand years.

The mismatch is stark: a density of worship comparable to Thor’s or Freyr’s, and almost total narrative silence. The simplest explanation is chronological — Ullr belongs to an early stratum of Germanic religion that had already receded by the time Christian Iceland wrote down the myths it still remembered.

What the ancient sources say

The standard portrait comes from Snorri Sturluson’s Gylfaginning (31), c. 1220: parentage, bow, skis, beauty, invocation in duels. The Skáldskaparmál supplies the poetic vocabulary — the kennings for Ullr, and the shield named as his ship.

The older Poetic Edda gives the two loaded mentions: Grímnismál (5) places Ydalir among the divine halls, and Atlakviða (30) attests the oath sworn on his ring. Saxo Grammaticus offers the only plot, in a euhemerised form that needs handling with care.

Archaeology and place-name evidence close the file, and here they outweigh the literature: the Thorsberg chape for the antiquity of the name, the Scandinavian toponyms for the reach of the cult.

Further reading

For his mother and the myth that defines her household, see Sif and then the story of the theft of Mjolnir, set off by her shorn golden hair. For his stepfather, read Thor; for the other deity of skis and the bow, Skadi. The sovereignty he borrows in Saxo belongs to Odin, and the stronghold he supposedly governed is described in Asgard.
