Bölthorn

Bölþorn (also Bölþor; Old Norse: Bǫlþorn [ˈbɔlˌθorn], "Evil-thorn") is a jötunn in Norse mythology, and the father (or grandfather) of Bestla, herself the mother of Odin, Vili and Vé. The figure receives mention in the Poetic Edda, composed in the 13th century from earlier traditional sources, and the Prose Edda, compiled by Icelander Snorri Sturluson in the 13th century. Scholars have noted that the Poetic Edda mention may mean that he is the father of the wise being Mímir.
