Dyggvi

Dyggvi is attested in early Scandinavian genealogical-legendary material. He appears in the skaldic poem Ynglingatal and in prose compendia derived from that poem, most notably Snorri Sturluson's Ynglinga saga (part of Heimskringla, c. 1225), and is included in the older Latin summary Historia Norwegiae and in the Íslendingabók succession list (Dómarr, Dyggvi, Dagr). These sources present him as a member of the House of Ynglings, son of Dómarr and father of Dagr (Dag the Wise). Later summary tradition reports that after death he 'became the concubine of Hel,' linking his fate to the Norse realm of the dead.

The supplied sources provide no physical description of Dyggvi. He is represented in the tradition as an earthly human king and genealogical figure—identified by familial relations and by his place in royal succession—rather than by any described bodily features or supernatural form.

The primary attestations do not attribute supernatural abilities to Dyggvi. He is presented in the sources in dynastic and familial terms (son of Dómarr, father of Dagr) and, according to Snorri's presentation of genealogical tradition, is noted as the first in his family to be called 'king.' The only postmortem status reported in later summary material is that he became a concubine of Hel; this is a statement about his fate after death rather than an ascription of active powers in life.
