The Wilton Diptych, a tempera picture on two folding panels showing Edward the Confessor’s mythical arms and Richard II’s white hart badge. Location, National Gallery, London.
The dexter half of the shield displays the commonly attributed arms of azure, a cross flory between five martlets or. The arms on the sinister (per quarterly azure seme de lis or and the second) are somewhat more mysterious. Since the arms of Edward the Confessor were assigned posthumously, my best guess is that the fleurs-de-lis refer to his French heritage by his mother, Emma of Normandy.
