crest

crest,

in feudal livery, an ornament of the headpiece that afforded protection against a blow. The term is incorrectly used to mean family coat of arms. Crests were widely used in the 13th cent. by feudal chiefs, as they had been by ancient Greek warriors and the Roman centurions. The earlier forms were usually of stuffed leather, gilded, silvered, or painted; later they were of wood or metal. The crest came to be used in heraldry, first only by persons of high rank, then by all those entitled to a coat of arms. It surmounts the escutcheon; its colors are those of the coat of arms. The dragon, wivern, and plume of feathers are common crests. The lion, used by Edward III of England, remains the crest of the English sovereigns. See also blazonry.

Crest

Ornament on a roof, a roof screen or wall, which is frequently perforated, and consists of rhythmic and identical decorative patterns.

Crest

 

(1) A bony protrusion in vertebrates and man that increases the area for muscle attachment. For example, the skulls of many mammals have, on the occipital and parietal bones, crests whose size depends upon the degree of development of the attached musculature. The sternum of flying birds has a high thin crest called the carina, to which the pectoral muscles, which draw the wings downward, are attached.

(2) A fleshy growth (in English, also called the comb) at the top of the head in some birds (many gallinaceans and accipi-ters, such as the American black vulture). In breeds of domestic fowl the crest takes a variety of forms (foliate, rosaceous, or nutlike). Varieties of chicken with well-developed tufts usually have no comb (for example, the Dutch and Padua hens).
