Merlínússpá (Prophecy of Merlin) is an Old Norse-Icelandic verse translation of Prophetiae Merlini in Geoffrey of Monmouth's Historia regum Britanniae.
It is notable for being the only translation of a foreign prose text into poetry in Old Norse-Icelandic literature and for being the earliest Arthurian text to have been translated in medieval Scandinavia.
In both Hauksbók and the version of Breta sögur preserved in the manuscript AM 573 4to, the poems are attributed to Gunnlaugr Leifsson.
[5] It is a close translation of the Prophetiae Merlini but also includes material from the Historia regum Britanniae.
[6][7] Although it is a close translation of its Latin exemplar, Merlínússpá uses imagery from Old Norse-Icelandic prose, which together with its meter give it "the semblance of an Eddic poem.
