What is "kvasir"

In Norse mythology, Kvasir was a being born of the saliva of the Æsir and the Vanir, two groups of gods. Extremely wise, Kvasir traveled far and wide, teaching and spreading knowledge. This continued until the dwarfs Fjalar and Galar killed Kvasir and drained him of his blood. The two mixed his blood with honey, resulting in the Mead of Poetry, a mead which imbues the drinker with skaldship and wisdom, and the spread of which eventually resulted in the introduction of poetry to mankind.

Kvasir is attested in the Prose Edda and Heimskringla, both written by Snorri Sturluson in the 13th century, and in the poetry of skalds. According to the Prose Edda, Kvasir was instrumental in the capture and binding of Loki, and an euhemerized account of the god appears in Heimskringla, where he is attested as the wisest among the Vanir.

Scholars have connected Kvasir to methods of beverage production and peacemaking practices among ancient peoples, and have pointed to a potential basis in Proto-Indo-European myth by way of Sanskrit vedas involving the holy beverage Soma and its theft by the god Indra.
