Fjörgyn / Fjörgynn

No continuous origin narrative survives for Fjörgyn or Fjörgynn in the cited materials. Instead the names appear in discrete attestations: the feminine Fjörgyn occurs in the Poetic Edda (Völuspá, where 'Fjörgyn’s son' is used as a kenning for Thor, and in Hárbarðsljóð as Thor's mother), while the masculine Fjörgynn is named in Snorri Sturluson's Prose Edda (Gylfaginning §9 and Skáldskaparmál §19) as the father of Frigg and is referenced in Lokasenna. Scholarly commentary suggests these names reflect an older Proto-Germanic/Proto-Indo-European lexical field for 'mountain' or 'wooded mountain' and may indicate an ancestral pairing or complementary earth-related concepts, but such reconstructions are theoretical and not recorded as narrative in the surviving Norse texts.

The sources provide no physical or iconographic descriptions of Fjörgyn or Fjörgynn. Attestations identify them by relational roles (mother of Thor; father of Frigg) and by usage as poetic synonyms for land, mountain, or earth. Thus, their 'appearance' in the corpus is primarily linguistic and genealogical: they are known through kennings, stanzaal references, and placement within divine family trees rather than by bodily attributes or visual portrayals.

No explicit powers, actions, or behavioral scripts are ascribed to Fjörgyn or Fjörgynn in the cited materials beyond their literary and genealogical functions. Fjörgyn functions as a poetic personification of the earth and features in kennings (e.g., 'Fjörgyn's son' for Thor). Fjörgynn is recorded as Frigg's father in Snorri's prose, a genealogical role. Scholarly hypothesis—based on etymology linking Proto-Germanic *fergunja to PIE roots associated with mountain and thunder deities (e.g., *Perkwunos)—proposes an underlying association with thunder or weather figures, but this is conjectural and not directly attested in the surviving Norse texts cited here.
