Sky's Edge

3 Early in time Ymir made his settlement,
there was no sand nor sea nor cool waves;
earth was nowhere nor the sky above,
a void of yawning chaos, grass was there nowhere

4 before the sons of Bur brought up the land-surface,
those who shaped glorious Midgard;
the sun shone from the south on the stone-hall,
then the ground was grown over with the green leek.

5 From the south, Sun, companion of the moon,
threw her right hand round the sky’s edge;
Sun did not know where she had her hall,
the stars did not know where they had their stations,
the moon did not know what might he had.

6 Then all the Powers went to the thrones of fate,
the sacrosanct gods, and considered this:
to night and her children they gave names,
morning they named and midday,
afternoon and evening, to reckon up in years.


- Poetic Edda, Voluspa


(Note: To be fair, the mention of the sky having an edge here [or "rim" in other translations] could just be poetic language.)
