Crest (heraldry) in the context of "Golden Hind"

A coat of arms is a heraldic visual design on an escutcheon (i.e., shield), surcoat, or tabard (the last two being outer garments), originating in Europe. The coat of arms on an escutcheon forms the central element of the full heraldic achievement, which in its whole consists of a shield, supporters, a crest, and a motto. A coat of arms is traditionally unique to the armiger (e.g. an individual person, family, state, organization, school or corporation). The term "coat of arms" itself, describing in modern times just the heraldic design, originates from the description of the entire medieval chainmail "surcoat" garment used in combat or preparation for the latter.

Rolls of arms are collections of many coats of arms, and since the early Modern Age centuries, they have been a source of information for public showing and tracing the membership of a noble family, and therefore its genealogy across time.

The lion is a common charge in heraldry. It traditionally symbolises courage, nobility, royalty, strength, stateliness and valour, because historically the lion has been regarded as the "king of beasts". The lion also carries Judeo-Christian symbolism. The Lion of Judah stands in the coat of arms of Jerusalem. Similar-looking lions can be found elsewhere, such as in the coat of arms of the Swedish royal House of Bjälbo, from there in turn derived into the coat of arms of Finland, formerly belonging to Sweden.

In heraldry, the term attitude describes the position in which a figure (animal or human) is emblazoned as a charge, a supporter, or as a crest. The attitude of a heraldic figure always precedes any reference to the tincture of the figure and its parts. Some attitudes apply only to predatory beasts, exemplified by the beast most usual to heraldry – the heraldic lion; other terms apply to docile animals, such as the doe, usually emblazoned as a "hind".

Other heraldic attitudes, such as volant (flying), describe the positions of birds, exemplified by the bird most usual to heraldry – the heraldic eagle; moreover, birds also are described by the positions of their wings. The term naiant (swimming) applies to fish, swans, ducks, and geese. The term segreant is applied to the griffin, as an approximation of rampant, and is applied to the dragon. Animal figures are positioned in profile, facing dexter (the viewer's left), and persons are shown affronté (facing the viewer), but the blazon might specify other attitudes.

The Horus name is the oldest known and used crest of ancient Egyptian rulers. It belongs to the "great five names" of an Egyptian pharaoh. However, modern Egyptologists and linguists are starting to prefer the more neutral term "serekh name". This is because not every pharaoh placed the falcon, which symbolizes the deity Horus, atop his (or in some cases, her) serekh.

Heraldry (also known as armory) is a discipline relating to the design, display, study and transmission of armorial bearings. A full heraldic achievement may include a coat of arms on a shield, helmet and crest, together with accompanying devices, such as supporters, badges, heraldic banners and mottoes. Heraldic achievements are formally described in a blazon.

Although the use of various devices to signify individuals and groups goes back to antiquity, both the form and use of such devices varied widely, as the concept of regular, hereditary designs, constituting the distinguishing feature of heraldry, did not develop until the High Middle Ages. It is often claimed that the use of helmets with face guards during this period made it difficult to recognize one's commanders in the field when large armies gathered together for extended periods, necessitating the development of heraldry as a symbolic language, but there is little support for this view.

The eagle is used in heraldry as a charge, as a supporter, and as a crest. Heraldic eagles can be found throughout world history like in the Achaemenid Empire or in the present Republic of Indonesia. The European post-classical symbolism of the heraldic eagle is connected with the Roman Empire on one hand (especially in the case of the double-headed eagle), and with Saint John the Evangelist on the other.

In heraldry, an achievement, armorial achievement or heraldic achievement (historical: hatchment) is a full display or depiction of all the heraldic components to which the bearer of a coat of arms is entitled. An achievement comprises not only the arms displayed on the escutcheon, the central element, but also the following elements surrounding it (from top to bottom):

• Slogan or war-cry
• Mantle and pavilion
• Crest placed atop a:
• Torse (or cap of maintenance as a special honour)
• Mantling
• Helm of appropriate variety; if holder of higher rank than a baronet, issuing from a:
• Coronet or crown (not used by baronets), of appropriate variety.
• Console (decorative or aesthetic in purpose, and not officially part of the armorial grant)
• Supporters (if the bearer is entitled to them, generally in modern usage not baronets), which may stand on a compartment
• Motto, if possessed
• Order, if possessed
• Badge, if possessed

A heraldic badge, emblem, impresa, or device, is a graphic symbol worn or displayed to indicate allegiance to, or the property of, an individual, family or corporate body. Medieval forms may also be called a livery badge, or a cognizance. Such badges are para-heraldic, as they do not necessarily use elements from the coat of arms of the person or family they represent – although many do, often borrowing from the crest or supporters. Their use is more flexible than that of arms proper.

Badges worn on clothing were common in the late Middle Ages, particularly in England. They could be made of base metal, cloth or other materials and worn on the clothing of the followers of the person in question; grander forms would be worn by important persons, with the Dunstable Swan Jewel in enamelled gold a rare survivor. Livery collars were also given to important persons, often with the badge as a pendant. The badge would also be embroidered or appliqued on standards, horse trappings, livery uniforms, and other belongings. Many medieval badges survive in English pub names.
