The Limitations of Heraldry Part 2
Arms of casual origin include the basic ordinaries of the chief, fesse, chevron, and pale and they probably owe their origin to the bands of metal added to a shield for the sake of increasing its strength. A very early instance is the gold pale (vertical band) on a red shield Gules a pale or, belonging to Hugh de Drandemesnil, in the reign of Henry I. Banded and studded shields appears on the pre-heraldic Bayeux Tapestry. Such shields became heraldic in character when the strengthening pieces were colored differently from the surface (field) of the shield upon which they were laid.
