In heraldry, mantling or lambrequin is drapery tied to the helmet above the shield. It forms a backdrop for the shield. In paper heraldry it is a depiction of the protective cloth covering (often of linen) worn by knights from their helmets to stave off the elements, and, secondarily, to decrease the effects of sword-blows against the helmet in battle, from which it is usually shown tattered or cut to shreds; less often it is shown as an intact drape, principally in those cases where clergy use a helmet and mantling (to symbolise that, despite the perhaps contradictory presence of the helmet, they have not been involved in combat), although this is usually the artist's discretion and done for decorative rather than symbolic reasons.
