The use of various symbols and devices to signify individuals and groups dates to the age of antiquity. Warriors often decorated their shields with patterns and mythological creatures.
Heraldry refers to the design, display and study of armorial bearings, a shield used to identify a person or family. The concepts and systems of regular heraldic designs were developed by heraldic officers between 1000AD and 1300AD during a period known as the High Middle Ages.
Originally conceived to assist with identification in battle, the beauty and intricacy of various heraldic designs meant that they survived the abandonment of armor on the battlefield and preserved the honor of the family line. To this day, we still see their use by individuals, organizations, corporations, towns, cities, and regions.
To blazon arms means to describe them in the language of Heraldry, which has its own vocabulary, syntax and grammar based strongly on an anglicized version of Norman-French.
