The Codex Regius is arguably the most important extant source on Norse mythology and Germanic heroic legends, and 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.
