Skíðblaðnir was the Norse mythological ship large enough to carry all the gods and their horses.
In mythological tradition, Skíðblaðnir was made by the dwarfs known as the sons of Ívaldi. The ship belonged to the god Freyr and always had a favorable wind when its sail was raised. It could be folded up like cloth and carried in a pouch when not in use.
The ship appears in the Prose Edda, written by the Icelandic historian Snorri Sturluson in the 13th century, and is also mentioned in skaldic poetry. It is distinct from Naglfar, the ship associated with the end of the world in Ragnarök. Skíðblaðnir’s magical folding ability and perfect sailing conditions make it a mythic object rather than evidence for a real Viking vessel.
