(plural Sagas). The northern mythological and historical traditions, chiefly compiled in the twelfth and three following centuries. The most remarkable are those of Lodbrok, Hervara, Vilkina, Volsunga, Blomsturvalla, Ynglinga, Olaf Tryggva-Sonar, with those of Jomsvikingia and of Knytlinga (which contain the legendary history of Norway and Denmark), those of Sturlinga and of knytlinga (which contain the legendary history of Iceland), the Heuns-Kringla and New Edda, due to Snorro-Sturleson.
All these legends are short, abrupt, concise, full of bold metaphor and graphic descriptions.
