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.
