Bestla

Bestla (Old Norse: [ˈbestlɑ]) is a jötunn in Norse mythology, and the mother of the gods Odin, Vili and Vé (by way of Borr). She is also the sister of an unnamed man who assisted Odin, and the daughter (or granddaughter depending on the source) of the jötunn Bölþorn. Odin is frequently called "Bestla's son" in both skaldic verses and the Poetic Edda.

Bestla is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, the Prose Edda, written in the 13th century by Snorri Sturluson, and in the poetry of skalds. Scholars have commented on the obscurity of the figure's name and have proposed various theories to explain the role and origin of the giantess.
