* The Poetic Edda: A collection of poems, primarily about Norse gods and heroes, compiled in the 13th century. It's also known as the *Codex Regius*.
* The Prose Edda: A 13th-century work by Snorri Sturluson, a scholar and historian, that explains the origins and myths of the Norse gods and heroes. It's also known as *Prose Edda* or *Snorra Edda*.
The term "Edda" itself is a bit of a mystery. It's thought to be derived from the Old Norse word *öðr*, meaning "wealth" or "prosperity."
So, "Eddas" collectively represents the main sources of Norse mythology and poetry, offering insights into their beliefs, values, and worldview.
