Appearing in western Europe in the late 9th century, the Nasal Helmet became the most common form of head protection in its time. Characterized by a single strip of metal protruding across the nose, providing protection for the face during combat.
With advances in metallurgical methods it become possible to construct helmets out of a single sheet of iron rather than the methods used in constructing earlier more complex Spangenhelm designs.
A mail coif would usually be worn beneath the helmet, providing additional protection to the head and neck.
The helmet began to loose popularity by the end of the 12th century as helmets that provided more protection to the face became more widespread. Such as the enclosed helmet and eventually the great helm. However Nasal Helmets were still used for some time by archers as it provided a better field of vision.
