Poetic Edda is the modern attribution for an unnamed collection of Old
Norse anonymous poems, which is different from the Edda written by
Snorri Sturluson. Several versions exist, all primarily of text from the
Icelandic medieval manuscript known as the Codex Regius. 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 by
its stories, but also by 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 by instead using alliterative devices and
strongly-concentrated imagery. Poets who have acknowledged their debt to
the Codex Regius include Vilhelm Ekelund, August Strindberg, J. R. R.
Tolkien, Ezra Pound, Jorge Luis Borges, and Karin Boye....
