Едда, or the Edda, is a collection of Old Norse poems and prose that are foundational to Norse mythology and Scandinavian literature. It consists of two main parts: the Poetic Edda, which contains mythological and heroic poems, and the Prose Edda, written by Snorri Sturluson in the 13th century, which serves as a guide to the myths and legends of the Norse gods. The Edda provides valuable insights into the beliefs, culture, and values of the Vikings and their understanding of the world. It features well-known figures such as Odin, Thor, and Loki, and explores themes of fate, heroism, and the nature of the cosmos.
