Codex Regius
The "Poetic Edda", also known as "Sæmundar Edda" or the "Elder Edda", is a collection of Old Norse poems from the Icelandic medieval manuscript Codex Regius ("Royal Book"). Along with the "Prose Edda", the "Poetic Edda" is the most expansive source on Norse mythology. The first part of the Codex Regius preserves poems that narrate the creation and foretold destruction and rebirth of the Old Norse mythological world as well as individual myths about gods concerning Norse deities. The poems in the second part narrate legends about Norse heroes and heroines, such as Sigurd, Brynhildr and Gunnar.
