The Icelandic Literary Saga, also known as the Edda, is an important collection of Old Norse poems and stories from the 13th century. It is one of the most important sources of Norse mythology and contains stories about gods, giants, and heroes. The Edda is divided into two parts: the Poetic Edda and the Prose Edda. The Poetic Edda is a collection of mythological and heroic poems, while the Prose Edda is a handbook of poetic language and style. Both parts are essential to understanding the culture and literature of medieval Iceland.
