Old Icelandic Sagas are a type of narrative literature that originated in Iceland during the 13th century. They are written in Old Norse and often focus on historical and legendary events. The term 'Edda' is used to refer to two different collections of Old Norse poetry, the Poetic Edda and the Prose Edda. The Poetic Edda is a collection of anonymous poems from the late 10th century, while the Prose Edda was written by the Icelandic scholar Snorri Sturluson in the 13th century. Both works contain stories about Norse mythology and heroic legends.
