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 typically feature a specific meter and are characterized by their use of alliteration and assonance, which create a musical quality in the verses. These poems were usually performed orally, often accompanied by music, and played a significant role in Icelandic culture. Rímur were popular among both the common people and the nobility, serving as a means of entertainment and a way to preserve Icelandic history and folklore.
