or shield of arms
Heraldic device dating to the 12th century in Europe.
It was originally a cloth tunic worn over or in place of armour to establish identity in battle. In the full armorial achievement the distinctively patterned shield is ornamented with a crest, helmet, mantling, motto, crown, wreath, and supporters and rests upon a compartment. Arms were later adopted as emblems for schools, churches, guilds, and corporations to reflect their origins or histories. See also heraldry .
