Alvíss
Alvíss (Old Norse: [ˈɑlˌwiːsː]; "All-Wise") was a dwarf in Norse mythology.[1]
In the "Alvíssmál" poem within the 12th century Poetic Edda, Thor's daughter, Þrúðr, was promised in marriage to Alvíss. Thor was unhappy with the match, however, so he devised a plan: Thor told Alvíss that, because of his small height, he had to prove his wisdom. Alvíss agreed, but Thor made his tests last until dawn, when Alviss, because he was a dwarf, was petrified on being exposed to the sunlight.[1]
