The event is attested primarily in the Poetic Edda, compiled in the 13th century from earlier traditional sources and the Prose Edda, written in the 13th century by Snorri Sturluson. Ragnarök is an important event in Norse mythology and has been the subject of scholarly discourse and theory in the history of Germanic studies. After these events, the world will resurface anew and fertile, the surviving and returning gods will meet and the world will be repopulated by two human survivors. In Norse mythology, Ragnarök ( / ˈ r æ ɡ n ə ˌ r ɒ k, ˈ r ɑː ɡ-/ ( listen) Old Norse: Ragnarǫk, 'Fate of the Gods') is a series of events, including a great battle, foretold to lead to the death of a number of great figures (including the gods Odin, Thor, Týr, Freyr, Heimdallr, and Loki), natural disasters and the submersion of the world in water.

The north portal of the 12th-century Urnes stave church has been interpreted as containing depictions of snakes and dragons that represent Ragnarök.
