The naturally mummified body of a Swedish "hustomte" or housegnome. They where said to be secret caretakers of the farms in scandinavia and would help with the farmer as long as he didn't do anything to upset the gnome, then he would get really nasty, throwing curses and killing lifestock.
the text inside the box translates:
This little house gnome was found by my father Jan Peter Petersson in the winter of 1866 inside the wall of the old barn , he was already long since dead.
Everything is built by me from scrach including the box. i really enjoyed making something that was based in the culture of my home-country.
