The Prose Edda
"How should one periphrase the earth? Thus: by calling her Flesh of Ymir, and Mother of Thor, Daughter of Ónarr, Odin's Bride, Co-Wife of Frigg and Rindr and Gunnlöd, Mother-in-law of Sif, Floor and Bottom of the Storm-Hall, Sea of Beasts, Daughter of Night, Sister of Audr and of Day. Even as Eyvindr Skald-Despoiler sang:
Now the beaming gold is hidden In the body of the Mother Of the Giants' Foe; the counsels Of a kindred strong are mighty.
As sang Hallfredr Troublous-Skald:
In council 't was determined That the King's friend, wise in counsel, Should wed the Land, sole Daughter Of Ónarr, greenly wooded.
And he said further:
The Raven-Abode's brave Ruler Got the broad-faced Bride of Odin, The Land, with kingly counsels Of weapons, lured unto him.
Even as Thjódólfr sang:
The Ruler, glad in Warriors, In the rowed hull doth fasten The ships of men to the strand's end, At the head of the sea keel-ridden.
As Hallfredr sang:
Full loath to let the Land slip I hold the lordly Spear-Prince Audr's sister is subjected To the splendid Treasure-Spender.
Thus sang Thjódólfr:
Far off the dart-slow sluggard Stood, when the Sword-Inciter In ancient days took to him The unripe Co-Wife of Rindr.
