Historical context: The great helm arose in the late 12th century as knights needed stronger protection against couched-lance and heavy-weapon blows. It offered unmatched face protection at the cost of vision and airflow; knights often removed it after the first clash, fighting on in the coif and cervelliere worn beneath."""@en ;
