InNorse mythology,Þrúðgelmir (Old Norse pronunciation:[ˈθruːð.ɟɛlmɪr];Old Norse "Strength Yeller") is ajötunn, the son of the primordialjötunnAurgelmir (whoSnorri Sturluson inGylfaginning identifies withYmir), and the father ofBergelmir. Þrúðgelmir hadone brother andone sister, who were elder than he was. Þrúðgelmir's name is sometimes anglicized asThrudgelmir. He may have been thejötunn born from Ymir's legs.^[1]

Þrúðgelmir appears in the poemVafþrúðnismál from thePoetic Edda. WhenOdin (speaking under the assumed nameGagnrad) asks who was the eldest of theÆsir or of thejötnar in bygone days,Vafþrúðnir answers:

"Uncountable winters before the earth was made,

thenBergelmir was born,

Thrudgelmir was his father,

and Aurgelmir his grandfather."

—Vafþrúðnismál(29)^[2]

According to Rudolf Simek, Þrúðgelmir is identical to the six-headed son that was begotten by Aurgelmir's feet (Vafþrúðnismál,33),^[3] but the fact that (apart from theþulur) he is mentioned in only one source led John Lindow to suggest that he might have been invented by the poet.^[4] Additionally, the identification of one with the other cannot be established with certainty since, according to stanza 33, Aurgelmir had more than one direct male offspring:

"They said that under the frost-giant's arms

agirl andboy grew together;

one foot with the other, of the wise giant,

begot a six-headed son."^[2]

Þrúðgelmir was drowned in his father's blood.
