The Aston mirror plate and its handle were found in ploughsoil, but were derived from a cremation burial which included two pottery vessels tentatively dated in the first century A.D. The area in which the discovery was made shows considerable activity in the Belgic and Romano-British periods. A detailed examination of the bronze mirror, using light-section photomicrography, indicates that it belongs in an East Anglian Ridge/Chiltern group, determined by techniques employed in the decoration.
