In Norse mythology, Gylfaginning contains the prose account of Ragnarok narrated by High. It is the first part of Snorri Sturluson’s Prose Edda, a major medieval Icelandic source for Norse mythology.
The text frames mythology as a dialogue. King Gylfi, disguised as Gangleri, questions three enthroned figures named High, Just-as-High, and Third. Their answers describe the gods, the world’s structure, the coming catastrophe, and the renewed world afterward.
Gylfaginning draws heavily on older poetic material, especially the Poetic Edda, but it is not itself a poem. Völuspá is the famous poem that gives the fullest poetic vision of Ragnarok, while Gylfaginning presents a connected prose retelling. Snorri wrote the work in the early thirteenth century.
