vair

In heraldry, vair refers to a specific pattern used on shields and other armorial bearings. Historically, it represented the fur of a squirrel, prized for its bluish-gray and white coloring, used ornamentally in medieval times.1

Heraldry itself is the art and science of hereditary symbols, originating as identification devices on flags and shields. These symbols, known as armorial bearings or coats of arms, were crucial for distinguishing individuals and groups, especially in warfare where literacy was low.23

In heraldic terms, "vair" specifically denotes a pattern composed of alternating rows of blue and white, resembling the squirrel fur. Variations exist, such as "vair ancient," which features horizontal bands of wavy silver and blue, and "vairé," used when tinctures other than silver and blue are employed.3456
