Edda, EHD uh, is a term that refers to two separate works of medieval Icelandic literature. The Poetic, or Elder, Edda is a collection of anonymous poems composed in the 1000's and 1100's. The Prose, or Younger, Edda is a textbook for poets that was written during the 1200's by the Icelandic poet and historian Snorri Sturluson. Snorri's work was the first to be called Edda, a name that may be related to an Icelandic word meaning song or poem. Later, the term was applied to the Elder Edda, too.
