Rímur are a traditional form of Icelandic epic poetry that originated in the medieval period. They consist of a series of rhymed stanzas, often recounting heroic tales, legends, or historical events. Rímur were typically performed orally and were an important part of Icelandic culture, especially during the 18th and 19th centuries. The structure of rímur usually involves a specific meter and rhyme scheme, making them distinct from other poetic forms. They often feature a narrative style, with characters and events that reflect the values and beliefs of Icelandic society. Rímur continue to be celebrated as a significant aspect of Icelandic literary heritage.
