Allfather; god of wisdom, poetry, war, seiðr, and the slain. Son of Borr and Bestla.

Odin (Old Norse Óðinn) stands at the apex of the Norse pantheon and bears the epithet Allfather. He is the son of Borr and the giantess Bestla, and brother to Vili and Ve, with whom he slew the primordial giant Ymir and shaped the world from his body. As ruler of Asgard and Valhalla he gathers the spirits of the battle-slain, the einherjar, who train for Ragnarok. His wife is Frigg, and among his many sons are counted Thor, Baldr, and Vidar.

Odin's hunger for wisdom is pervasive throughout the sources. Hávamál 138-141 describes how he hung himself nine nights in Yggdrasil, pierced by his own spear Gungnir, without food or drink, in order to acquire the secrets of the runes. The sacrifice is auto-sacrificial, directed at himself: 'gefinn Óðni, sjálfr sjálfum mér.' He also sacrificed one eye at Mimir's well to drink of primordial wisdom (Völuspá 28), and he visits the giant Vafthrudnir in a contest of knowledge (Vafþrúðnismál), revealing his command over the nine worlds.

As a war god Odin selects the battle-slain and steers the outcome of combat, often favoring whomever he chooses regardless of righteousness, a point Lokasenna 22 and Hárbarðsljóð make explicit. His spear Gungnir is cast over the enemy host to consecrate them to death. His role as a practitioner of seiðr is remarkable: Lokasenna 24 taunts him for practicing ergi (feminized magic), underscoring the gender-transgressive nature of seiðr. His ravens Huginn (thought) and Muninn (memory) fly daily over all worlds and report back to him (Grímnismál 20).

Odin's connection to poetic art derives from the myth of the mead of poetry, which he acquired from the giant Suttung. In Skáldskaparmál Snorri Sturluson recounts how Odin transformed into a serpent, penetrated the mountain Hnitbjorg, seduced Gunnlod, and drank the three vessels Odrerir, Son, and Bodn before escaping as an eagle and disgorging the mead in Asgard. He is also associated with the art of galdr (incantation) and possesses the ability to change his form at will.

At Ragnarok Völuspá foretells that Odin is torn apart by Fenrir, but that his son Vidar avenges him. Despite his immense power, Odin remains subject to the Norns and constantly seeks knowledge to delay the end. This tragic dimension, supreme power constrained by fate, forms the core of his character and recurs throughout the Eddic corpus.

Interpretive traditions

A What we know

Odin is the chief deity of the Eddic pantheon and is called Allfather in Gylfaginning and Grímnismál.

His self-sacrifice in Yggdrasil and acquisition of runes is a central, well-attested myth (Hávamál 138-141).

His ravens are named Huginn and Muninn and function as information-gatherers (Grímnismál 20).

He practices seiðr, a form of magic associated with feminine gender roles (Lokasenna 24, Ynglinga saga 7).

B What we think we know

Whether Odin's one-eyedness is an original feature or a later narrative elaboration is debated among scholars such as McKinnell and Schjødt.

The identification of Odin with the continental Germanic deities Wotan/Mercurius is assumed but methodologically debated.

Whether the seiðr tradition reflects actual cultic practice or is a literary construction remains an open question.

C What we do not know

Whether a unified Odin cult with shared ritual practice existed in pre-Christian Scandinavia is unknown.

The origin of the rune-acquisition myth, whether it is indigenous or influenced by southerly traditions, has not been established.
