Is Freyr the same person as Odin? I know that's a hot topic everywhere.

The reason I ask is that Man, Myth & Magic, The Illustrated Encyclopedia of Mythology, Religion and The Unknown says on page 965 "Freyr had his own ship, Skipbladnir, said to be large enough to hold all the gods, but small enough to fold away in a pouch when not in use." Yet, I read that Odin has the same set up. The ship could travel at incredible, one might even say warp, speed.

This may not sound logical unless the gods are tiny, "quantumly" small, and space is folded in some way.

Skipbladnir was a longboat. Long things were venerated: longhouses, long beards, longboats, etc.

These days people tend to travel in ships of the air (am I kenning ?) to airports with names like Schiphol, which name is said to mean "ship hell".
