Odin

Odin appears throughout the Poetic Edda under an unusually large number of alternate names, or heiti, and the poem Grimnismal alone has the god list dozens of them himself while disguised and tortured between two fires in King Geirrod's hall, names including Wanderer, Grim the Masked One, and All Father, each pointing to a different facet of his character, deception, concealment, ultimate authority over the other gods. This proliferation of names reflects a broader pattern in how Odin is portrayed across the Eddas: he moves through the nine worlds in disguise more often than he appears openly, seeking hidden knowledge wherever it can be found, consulting a dead seeress in the poem Voluspa to learn the fate of the gods from creation through Ragnarok, and trading an eye at Mimir's well for a single drink from the well of wisdom. The Prose Edda, compiled by the Icelandic scholar Snorri Sturluson in the thirteenth century from older poetic and oral material, systematizes this wisdom seeking persona alongside Odin's standing as ancestor of kings, since royal genealogies in medieval Scandinavia and Anglo-Saxon England alike traced their ruling lines back to Odin under his various regional names, using his descent as a direct claim to legitimate authority. Odin's identity in the surviving literature is therefore built less around a single defining myth than around this combination, a god defined by disguise, sought knowledge and the royal lines that claimed descent from him specifically because of it.

Odin's worship in pre-Christian Scandinavia appears to have been genuinely concentrated among kings and the aristocracy rather than widespread at every social level, and the surviving evidence for it is more uneven than his later fame suggests. Place names invoking Odin himself are comparatively sparse across Scandinavia, in contrast to his Anglo-Saxon cognate Woden, whose name survives in numerous English place names such as Wednesbury and Woodnesborough, and who gave English the word Wednesday, Woden's day. The most detailed surviving description of Norse temple sacrifice comes from Adam of Bremen's eleventh century ecclesiastical history, which describes a great nine year festival at the temple of Uppsala where statues of three gods sat enthroned together, Thor at the center flanked by Wodan and Fricco, with sacrifices directed to whichever god suited the community's need, to Wodan specifically in time of war. Adam was a Christian cleric writing decades after the events he describes and with an evident polemical purpose, so historians treat his account as valuable but not neutral, a starting point requiring other evidence rather than a direct transcript of practice. Separately, Norse literary sources describe warriors ritually dedicating an enemy army to Odin by casting a spear over its ranks while declaring Odin owns you all, a practice tied to Odin's role as gatherer of battle's slain and reflecting a cult genuinely concentrated on war, kingship and elite ritual rather than on ordinary agricultural or household worship.
