Aurboða
In Norse mythology, Aurboða (also Aurboda) (Old Norse "gravel-bidder" or "gravel-offerer") is a mountain jötunn, wife to the jötunn Gymir, and mother of Gerðr. 
Aurboða is attested in the "Poetic Edda"; compiled in the 13th century from earlier traditional sources, and the "Prose Edda" written in the 13th century by Snorri Sturluson. Aurboða is also the name of one of nine maidens who sit at the knees of Menglöd in the poem "Svipdagsmál". "Aurboða" is sometimes anglicized as "Aurboda".
