The EDDAS are two collections of Old Norse poetry and prose, written in Iceland during the 13th century. They are the primary sources of Norse mythology and contain stories of gods, giants, dwarves, and other mythical creatures. The Poetic Edda is a collection of anonymous poems, while the Prose Edda was written by the Icelandic historian Snorri Sturluson. Both works provide insight into the beliefs and customs of the ancient Norse people.
