In Norse mythology, Ragnarök (/ˈræɡnəˌrɒk, ˈrɑːɡ-/ (audio speaker iconlisten); Old Norse: Ragnarǫk [ˈrɑɣnɑˌrɔk], "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. 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. Ragnarök is an important event in Norse mythology and has been the subject of scholarly discourse and theory in the history of Germanic studies.
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. In the Prose Edda and in a single poem in the Poetic Edda, the event is referred to as Ragnarøkkr [ˈrɑɣnɑˌrøkːz̠] (Old Norse for 'Twilight of the Gods'), a usage popularised by 19th-century composer Richard Wagner with the title of the last of his Der Ring des Nibelungen operas, Götterdämmerung (1876), which is "Twilight of the Gods" in German.
