This is a pair of Icelandic “Necropants.” Made from human skin, sorcerers and witches would wear these trousers all day and night under their clothes as a sort of underwear in order to bring them wealth. Politely being asked by your sorcerer friend to be used in a pair of Necropants after your death was a great honor in 17th century Iceland.
In order to make the magical trousers, the living man would have to strip the skin off of the corpse in one piece. The wearer of the pants then had to steal a coin from a widow and store it in the scrotum of the trousers next to a magical sign called a nábrókarstafur.
The coin was a “tool to gather wealth by supernatural means.”
The skin of the pants would then stick to the wearer’s own flesh. “They would immediately be stuck with your own flesh and be part of your body,” said a museum spokesman.
“People would be able to use them as long as they lived, but they would have to get rid of them before they die. If they would find someone to take them over they could last forever,” the spokesman said.
