Escutcheon (heraldry)

In heraldry, an escutcheon (/ᵻˈskʌtʃən/) is a shield which forms the main or focal element in an achievement of arms. The word is used in two related senses.

Firstly, as the shield on which a coat of arms is displayed. Escutcheon shapes are derived from actual shields used by knights in combat, and thus have varied and developed by region and by era. As this shape has been regarded as a war-like device appropriate to men only, British ladies customarily bear their arms upon a lozenge, or diamond-shape, while clergymen and ladies in continental Europe bear theirs on a cartouche, or oval. Other shapes are in use, such as the roundel commonly used for arms granted to Aboriginal Canadians by the Canadian Heraldic Authority.
