Question: Völuspá is the best known poem of a collection of poems in what culture?

Blood and the Moon is a poem by Irish poet William Butler Yeats written in 1928 and published in the collection "The Winding Stair" in 1929 before being reprinted in The Winding Stair and Other Poems in 1933.  Yeats composed the poem in response to the 1927 assassination of Kevin O'Higgins, the Vice-President of the Free State, whom Yeats had known personally.  The poem contains many themes common in Yeats's poems from the 1920s including the "tower", a reference to "Thoor Ballylee", which had been the title of a collection of works printed the year before "Blood and the Moon" was published, as well as the "gyre" which had been a major focus of his 1920 poem "The Second Coming". <SEP>  Several versions exist, all consisting 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, and from the early 19th century onwards, it has had a powerful influence on later Scandinavian literatures, not merely by the stories it contains but also by the visionary force and 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 working without any final rhyme by instead using alliterative devices and strongly-concentrated imagery. 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.  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. <SEP> The Testament of Cresseid is a narrative poem of 616 lines in Middle Scots, written by the 15th-century Scottish makar Robert Henryson.  It is his best known poem.  It imagines a tragic fate for Cressida in the medieval story of "Troilus and Criseyde" which was left untold in Geoffrey Chaucer's version.  Henryson's cogent psychological drama, in which he consciously resists and confronts the routine depiction of Cressida (Cresseid) as simply 'false', is one of the features that has given the poem enduring interest for modern readers and it is one of the most admired works of northern renaissance literature.  A modern English translation by Seamus Heaney, which also included seven of Henryson's fables from "The Morall Fabillis", was published in 2009. <SEP>  It tells the story of the creation of the world and its coming end, related to the audience by a völva addressing Odin.  It is one of the most important primary sources for the study of Norse mythology. Völuspá (Old Norse Vǫluspá or Vǫluspǫ́, "Prophecy of the Völva (Seeress)"; reconstructed Old Norse ] , Modern Icelandic ] ) is the first and best known poem of the Poetic Edda.  Henry Adam Bellows proposed a 10th-century dating and authorship by a pagan Icelander with knowledge of Christianity.  He also assumes the early hearers would have been very familiar with the "story" of the poem and not in need of an explanation.
