Alvíssmál

The Alvíssmál ('the lay of Alvíss') is a 12th century mytholgical poem in the Poetic Edda about Þórr's outwitting of the dwarf Alvíss:

Alvíss has been promised the hand of Þórr's daughter in marriage, and he arrives for the wedding. But then Þórr demands, as a condition for the wedding, that he must answer some questions: the names for earth, heaven, moon, sun, clouds, wind, calm, fire, sea, wood, night, corn and beer. Alvíss answers the questions and finally, a beam of sunlight falls into the hall and the dwarf turns to stone.
