The escutcheon simply represents smaller shield shapes included within the shield, and its close relative, the inescutcheon is just a larger version occupying most of the field. A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Escutcheon There is no particular significance that can accorded to the escutcheon itself, but attention should be paid to the colour and devices that are borne upon it. The escutcheon may also be added to an existing coat of arms either as recognition of some additional honour (an escutcheon of augmentation”) or in the case where arms that are already quartered are to be combined an escutcheon with the new arms may be placed overall (an “escutcheon of pretence”).
