This category is for Norse mythology, the myths of the Scandinavians (Sweden, Denmark, Norway, and Iceland). The main source for Norse mythology is the Icelandic Edda. Included in this category is Teutonic mythology, which is related, but not identical, to Norse mythology. The first to study Teutonic mythology systematically were the Grimm brothers. The term Germanic mythology may refer to either Norse or Teutonic mythology, or both.
Edda is the name of two Old Norse writings which constitute the most authoritative source for Norse mythology: the Elder, or Poetic, Edda, dealing with Norse mythology (compiled ca. 1250 based on older materials), and the Younger, or Prose, Edda, composed by Snorri Sturluson (ca. 1220), containing various mythological stories, as well as a treatise on poetry.
