Escutcheon (heraldry) in the context of "Freemasonry"

A cardinal is a senior member of the clergy of the Catholic Church. As titular members of the clergy of the Diocese of Rome, they serve as advisors to the pope, who is the bishop of Rome and the visible head of the worldwide Catholic Church. Cardinals are chosen and formally created by the pope, and typically hold the title for life. Collectively, they constitute the College of Cardinals. The most solemn responsibility of the cardinals is to elect a new pope in a conclave, almost always from among themselves, with a few historical exceptions, when the Holy See is vacant.

During the period between a pope's death or resignation and the election of his successor, the day-to-day governance of the Holy See is in the hands of the College of Cardinals. The right to participate in a conclave is limited to cardinals who have not reached the age of 80 years by the day the vacancy occurs. With the pope, cardinals collectively participate in papal consistories, in which matters of importance to the Church are considered and new cardinals may be created. Cardinals of working age are also often appointed to roles overseeing dicasteries (departments) of the Roman Curia, the central administration of the Catholic Church.

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.

Ecclesiastical heraldry refers to the use of heraldry within Christianity for dioceses, organisations and Christian clergy. Initially used to mark documents, ecclesiastical heraldry evolved as a system for identifying people and dioceses. It is most formalized within the Catholic Church, where most bishops, including the Pope, have a personal coat of arms. Clergy in Anglican, Lutheran, Eastern Catholic and Eastern Orthodox churches follow similar customs, as do institutions such as schools and dioceses.

Ecclesiastical heraldry differs notably from other heraldry in the use of special insignia around the shield to indicate rank in a church or denomination. The most prominent of these insignia is the low crowned, wide brimmed ecclesiastical hat, commonly the Roman galero. The color and ornamentation of this hat indicate rank. Cardinals are famous for the "red hat", while other offices and churches have distinctive colors of hat, such as black for priests and green for bishops, customarily with a defined number of tassels that increases with rank.

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.

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 coat of arms of Greece (Greek: Εθνόσημο, lit. 'national emblem', [eθˈnosimo] ) comprises a white Greek cross on a blue escutcheon, surrounded by two laurel branches. It has been in use in its current form since 1975. Prior to the adoption of the current coat of arms, Greece used a number of different designs, some of which were not heraldic; the first heraldic design was introduced in 1832 and its main element, the blue shield with the white cross, has been the base for all other national coats of arms since then. The design is a heraldic representation of the Greek national flag adopted in 1822, which featured a white cross on a blue field.

In heraldry, a charge is any emblem or device occupying the field of an escutcheon (shield). That may be a geometric design (sometimes called an ordinary) or a symbolic representation of a person, animal, plant, object, building, or other device. In French blazon, the ordinaries are called pièces, and other charges are called meubles ('mobile [things]').

The term charge can also be used as a verb; for example, if an escutcheon depicts three lions, it is said to be charged with three lions; similarly, a crest or even a charge itself may be "charged", such as a pair of eagle wings charged with trefoils (as on the coat of arms of Brandenburg). It is important to distinguish between the ordinaries and divisions of the field, as they typically follow similar patterns, such as a shield divided "per chevron", as distinct from being charged with a chevron.
