An illustration of a battle outside Antioch shows Crusaders in the round-topped great helms that had become standard by the late 13th century (A). The Muslims wield falchions (B) but the placing of this unlikely weapon in the hands of 'infidels' was probably an artist's way of interpreting the curved swords that he knew the Turks commonly used.
