A cervelliere is a close-fitting skull cap of iron or steel, used mainly by footmen in the early medieval period. It was most often worn under or over a maille coif. Of course, gambeson padding was also worn underneath. Only protecting the cranium, the cervelliere was mass produced for the common foot soldier throughout Europe. It became outdated with the rise in archery during the middle of the medieval period, later replaced by helms that protected the whole face.
