Heraldry
Elements of an achievement

A heraldic achievement consists of a shield of arms, the coat of arms, or simply coat, together with all of its accompanying elements, such as a crest, supporters, and other heraldic embellishments. The term " coat of arms " technically refers to the shield of arms itself, but the phrase is commonly used to refer to the entire achievement. The one indispensable element of a coat of arms is the shield; many ancient coats of arms consist of nothing else, but no achievement or armorial bearings exists without a coat of arms.

From a very early date, illustrations of arms were frequently embellished with helmets placed above the shields. These in turn came to be decorated with fan-shaped or sculptural crests, often incorporating elements from the shield of arms; as well as a wreath or torse, or sometimes a coronet, from which depended the lambrequin or mantling. To these elements, modern heraldry often adds a motto displayed on a ribbon, typically below the shield. The helmet is borne of right, and forms no part of a grant of arms; it may be assumed without authority by anyone entitled to bear arms, together with mantling and whatever motto the armiger may desire. The crest, however, together with the torse or coronet from which it arises, must be granted or confirmed by the relevant heraldic authority.

If the bearer is entitled to the ribbon, collar, or badge of a knightly order, it may encircle or depend from the shield. Some arms, particularly those of the nobility, are further embellished with supporters, heraldic figures standing alongside or behind the shield; often these stand on a compartment, typically a mound of earth and grass, on which other badges, symbols, or heraldic banners may be displayed. The most elaborate achievements sometimes display the entire coat of arms beneath a pavilion, an embellished tent or canopy of the type associated with the medieval tournament, though this is only very rarely found in English or Scots achievements.
