The Symbolism of Heraldry Part 4 “Augmentation”
Augmentation, or augmentation of honor, is a term describing the addition to a coat of arms at a later date to the original granting of the arms. This augmentation is usually granted by a sovereign to commemorate worthy or illustrious deeds. These augmentations usually take the form of an escutcheon ( a smaller shield within the arms), a canton ( a square in the top left of the arms), or an additional charge to the arms.
