In Norse mythology, Freyr’s magical ship that can fold small enough to fit in a pouch is called Skíðblaðnir. It is one of the divine treasures crafted by the dwarfs.
The ship is large enough to hold all the gods and their weapons, yet it can be folded and carried when not in use. It also always has a favorable wind, making it an exceptionally useful magical vessel.
Skíðblaðnir is distinct from Naglfar, the ship associated with Ragnarok and the enemies of the gods. The similar nautical context can lead readers to merge the two vessels.
The ship’s name is written with different spellings in English because Old Norse letters and accents are transliterated in several ways. Skidbladnir is a common anglicized form.
