Pope Martin IV
During a fight in Staßfurt in 1280, Otto was hit by an arrow. Allegedly, he lived for a year with an arrow sticking out of his head, hence his nickname. It is not quite clear how long he walked around like that; one tradition says "for some time", another says "for many years". There are no written sources to resolve this. Eric was finally appointed Bishop of Magdeburg in 1283, after Pope Martin IV had given his blessing.
