Elli

Elli appears only in the narrative of Gylfaginning within Snorri Sturluson’s Prose Edda. In that episode, during a series of challenges set by Útgarða-Loki, an 'old woman, stricken in years' is called forth from the giant’s hall to wrestle Thor. After the contest Útgarða-Loki explains that the figure was not merely an elderly woman but the personification of Old Age, summoned to demonstrate that aging is an inexorable condition even for the gods. No genealogical origin or broader mythic biography for Elli is provided in the extant text, and Elli is not attested in other surviving Norse sources.

The Prose Edda describes Elli as 'the old woman, stricken in years.' The surviving account emphasizes advanced age rather than distinctive physical attributes; she presents to observers as an elderly woman whose appearance signals the concept she embodies—old age—rather than serving as a richly detailed individual portrait.

In the Gylfaginning episode Elli’s operative power is conceptual and demonstrative: as the personification of Old Age she causes even the mighty to weaken. During the wrestling-match with Thor, the harder he strove the firmer she stood, and when she applied a hold Thor became unsteady and fell to one knee. The text frames this not as malice but as the inexorable function of aging; no additional supernatural powers or a wider catalogue of deeds are attested in the surviving source.
