In Norse mythology, Dyggvi or Dyggve (Old Norse "Useful, Effective") was a Swedish king of the House of Ynglings. Dyggvi died and became the concubine of Hel, Loki's daughter. Dyggvi was succeeded by his son Dag the Wise.
Snorri Sturluson wrote of Dygvvi's father Domar in his Ynglinga saga (1225):
About Dyggvi's mother Snorri had more to say:
In his Ynglinga saga, Snorri Sturluson included a piece from Ynglingatal composed in the 9th century:
The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation:
The even earlier source Íslendingabók also cites the line of descent in Ynglingatal and it also gives Dyggvi as the successor of Dómarr and the predecessor of Dagr: ix Dómarr. x Dyggvi. xi Dagr.
This is just where the story begins,
so get up, pull your head in
The pride, the guts, the strength, the will,
of the youth is born, and we’ll never be torn
You’ll find us anywhere and everywhere,
at anytime but this time is the time we care
Reach out, sing out “brace your self for the ride you got to hold on tight”
Reach out, and realize, we are the youth this year call out so all can hear
Punch your words in the air, we are the youth who care
Seek for, one more lover & friend, wait for it to all begin
With hands up high, we say good bye, to the things we fear,
come on join in my dear
You’ll find us anywhere and everywhere,
at anytime but this time is the time we care,
it’s the time we care
This is just were the story begins
The Pride, the guts, the strength,
the will of the youth is born
