Skíðblaðnir (Old Norse: , 'assembled from thin pieces of wood'), sometimes anglicized as Skidbladnir or Skithblathnir, is the best of ships in Norse mythology. It is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and in the Prose Edda and Heimskringla, both written in the 13th century by Snorri Sturluson. All sources note that the ship is the finest of ships, and the Poetic Edda and Prose Edda attest that it is owned by the god Freyr, while the euhemerized account in Heimskringla attributes it to the magic of Odin. Both Heimskringla and the Prose Edda attribute to it the ability to be folded up–as cloth may be–into one's pocket when not needed. Attestations References to the ship occur in the Poetic Edda, the Prose Edda, and in Heimskringla. The ship is mentioned twice in the Poetic Edda and both incidents therein occur in the poem Grímnismál. In Grímnismál, Odin (disguised as Grímnir), tortured, starved, and thirsty, imparts in the young Agnar cosmological knowledge, including information about the origin of the ship Skíðblaðnir: Skíðblaðnir is mentioned several times in the Prose Edda, where it appears in the books Gylfaginning and Skáldskaparmál. The first mention of Skíðblaðnir in the Poetic Edda occurs in chapter 43, where the enthroned figure of High tells Gangleri (king Gylfi in disguise) that the god Odin is an important deity. High quotes the second of the above-mentioned Grímnismál stanzas in support. The boat is first directly addressed in chapter 43; there Gangleri asks that, if Skíðblaðnir is the best of ships, what there is to know about it, and asks if there is no other ship as good or as large as it. High responds that while Skíðblaðnir is the finest ship and the most ingeniously created, the biggest ship is in fact Naglfar, which is owned by Muspell. The Sons of Ivaldi, who High adds are dwarfs, crafted the ship and gave it to Freyr. High continues that the ship is big enough for all of the gods to travel aboard it with wargear and weapons in tow, and that, as soon as its sail is hoisted, the ship finds good wind, and goes wherever it need be. It is made up of so many parts and with such craftsmanship that, when it is not needed at sea, it may be folded up like cloth and placed into one's
