The Islandic magical stave for necropants
After tanning, the sorcerer wore the skin like a pair of pants. As soon as he stepped into the pants they will stick to his own skin. A coin must be stolen from a poor widow and placed in the scrotum along with a magical sign (stave), written on a piece of paper. This reputedly attracted more coins and hence the sorcerer became wealthy.
Before his death, the sorcerer had to pass the necropants to another. He did this by having the new owner place his right leg in one side of the pants whilst the sorcerer still has his left leg in the other. In this way, the power of the pants would pass from one individual to another. The Museum of Witchcraft and Sorcery in Iceland has a pair of necropants on display.
