The spangenhelm was a helmet in the early middle ages that was later replaced by the nasal helmet. It was constructed of three to six metal plates, of bronze or steel, that riveted to metal frame. It fit closely to the head and came to a point on top. Optional components included a partial aventail of flaps of leather or metal for the ears. Face protection could be provided by a full face mask, a frame of metal around the eyes only, or a nasal piece to protect the nose.
