Imagine finding a really old metal glove at the bottom of the sea! That's what happened to some explorers in a place called Oslo, Norway.
This glove is super special because it's from a long time ago, like hundreds of years ago! It was used by knights to protect their hands during battles.
It's super rare to find something like this because it was very expensive back then, and most people couldn't afford it.
It's like finding a treasure chest full of amazing things from the past!
