[3] In Vafþrúðnismál (The Lay of Vafþrúðnir), Bergelmir is portrayed as the son of Þrúðgelmir and the grandson of the first jötunn Aurgelmir (Ymir).
When Odin asks Vafthrúdnir who is the oldest among the æsir and the jötnar,[1] the wise jötunn responds that: A great many years before the earth was formed, Bergelmir was born; Thrúdgelmir was the father of this one, And Aurgelmir the grandfather.
In Gylfaginning (The Beguiling of Gylfi), while the blood of Ymir (Aurgelmir) is flooding the earth after the sons of Borr (Odin, Vili, and Vé) have killed him, Bergelmir is likewise pictured as escaping on a lúðr with his wife to re-found the frost-jötunn race.
Based upon Snorri's account, the Old Norse word lúðr might have referred to a 'coffin',[2][5] a 'cradle',[2] a 'chest', or some wooden part of a mill.
But Snorri does add the crucial element not made in the explicit verses, that the lúðr is to serve as a floating vessel.
