There are four legends concerning Prometheus:
According to the first he was clamped to a rock in the Caucasus for betraying the secrets of the gods to men, and the gods sent eagles to feed on his liver, which was perpetually renewed.
According to the second Prometheus, goaded by the pain of the tearing beaks, pressed himself deeper and deeper into the rock until he became one with it.
According to the third his treachery was forgotten in the course of thousands of years, forgotten by the gods, the eagles, forgotten by himself.
According to the fourth everyone grew weary of the meaningless affair. The gods grew weary, the eagles grew weary, the wound closed wearily.
There remained the inexplicable mass of rock. The legend tried to explain the inexplicable. As it came out of a substratum of truth it had in turn to end in the inexplicable.

For people who are actually interested in how viking music might have sounded, “Drømde mik en drøm i nat" (/I dreamt a dream last night) is the earliest music (and lyrics) known in Scandinavia preserved on the last page of the (~1200-1300) Codex Runicus as rune notes.
The song and melody is still known and used today in most of Scandinavia, as a sort of folk-standard. This version, deceivingly slow in the beginning, is presented as close to the original sound of the years 900-1000 as historians think they can come.
This song might have survived because it was a gigantic hit, like the viking’s very own “Billie Jean”. A total pop slayer that stayed around long enough for music notes to be invented.
