31. But the loved one fair | of the giant found
A counsel true, | and told her thought:
"Smite the skull of Hymir, | heavy with food,
For harder it is | than ever was glass."

32. The goats' mighty ruler | then rose on his knee,
And with all the strength | of a god he struck;
Whole was the fellow's | helmet-stem,
But shattered the wine-cup | rounded was.

- Poetic Edda (Hymiskvitha)
