 The "Codex Regius" is arguably the most important extant source on Norse mythology and Germanic heroic legends.From the early-19th century onwards it has had a powerful influence on later Scandinavian literatures - not only through its stories, but also through the visionary force and the dramatic quality of many of the poems.It has also become an inspiring model for many later innovations in poetic meter, particularly in Nordic languages, offering many varied examples of terse, stress-based metrical schemes that lack any final rhyme but instead use alliterative devices and strongly-concentrated imagery.
