Coat of arms of Hastings, showing a partially dimidiated shield, where the front halves of the upper and lower lions are joined to the rear halves of ships. This motif features widely in the heraldry of the Cinque Ports.Horizontally dimidiated rabbit and fish, arms of the town and gmina of Prochowice, SW Poland. Horizontal dimidiations are rare, if not unknown, in English heraldry.Coat of arms of the consolidated commune of Les Andelys, dimidiated (French: Mi-parti) per pale, three droops of grapes and three castle keeps. Dimidiations are rare in French heraldry.
For a time, dimidiation preceded the method known as impalement. Whereas impalement involves placing the whole of both coats of arms side by side in the same shield, dimidiation involves placing the dexter half of one coat of arms alongside the sinister half of the other. In the case of marriage, the dexter half of the husband's arms would be placed alongside the sinister half of the wife's arms.
The practice fell out of use because the result was not always aesthetically pleasing (sometimes creating strange hybrids), and also because in some cases, it would have resulted in a shield that confusingly looked like one coat of arms rather than a combination of two. For instance, a bend combined with a bend sinister might result in a combination that simply looked like a chevron, thus hiding the fact that two coats of arms had been combined.
In order to avoid these drawbacks, it became customary to use more than half of each coat of arms when combining them through dimidiation. Once this practice had begun, the logical progression was to include the whole of both coats of arms in the new shield, so that in effect, impalement replaced dimidiation as a method of combining coats of arms.
A general rule which carries over from dimidiation to impalement is that if a coat of arms with a bordure (or tressure, orle, etc.) is impaled, the bordure should not continue down the line of impalement.

Heraldry is a discipline relating to the design, display and study of armorial bearings, as well as related disciplines, such as vexillology, together with the study of ceremony, rank and pedigree. Armory, the best-known branch of heraldry, concerns the design and transmission of the heraldic achievement. The achievement, or armorial bearings usually includes a coat of arms on a shield, helmet and crest, together with any accompanying devices, such as supporters, badges, heraldic banners and mottoes.
In heraldry, the field (background) of a shield can be divided into more than one area, or subdivision, of different tinctures, usually following the lines of one of the ordinaries and carrying its name. Shields may be divided this way for differencing or for purposes of marshalling, or simply for style. The lines that divide a shield may not always be straight, and there is a system of terminology for describing patterned lines, which is also shared with the heraldic ordinaries.
The lines in heraldry used to divide and vary fields and charges are by default straight, but may have many different shapes. Care must be taken to distinguish these types of lines from the use of lines as charges, and to distinguish these shapes from actual charges, such as "a mount [or triple mount] in base," or, particularly in German heraldry, different kinds of embattled from castle walls.
In heraldry, variations of the field are any of a number of ways that a field may be covered with a pattern, rather than a flat tincture or a simple division of the field.
In heraldry, cadency is any systematic way to distinguish arms displayed by descendants of the holder of a coat of arms when those family members have not been granted arms in their own right. Cadency is necessary in heraldic systems in which a given design may be owned by only one person at any time, generally the head of the senior line of a particular family.
In heraldry, an ordinary is one of the two main types of charges, beside the mobile charges. An ordinary is a simple geometrical figure, bounded by straight lines and running from side to side or top to bottom of the shield. There are also some geometric charges known as subordinaries, which have been given lesser status by some heraldic writers, though most have been in use as long as the traditional ordinaries. Diminutives of ordinaries and some subordinaries are charges of the same shape, though thinner. Most of the ordinaries are theoretically said to occupy one-third of the shield; but this is rarely observed in practice, except when the ordinary is the only charge.
In heraldry, a bend is a band or strap running from the upper dexter corner of the shield to the lower sinister. Authorities differ as to how much of the field it should cover, ranging from one-fifth up to one-third.
In heraldry, a charge is any emblem or device occupying the field of an escutcheon (shield). That may be a geometric design 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.
The coat of arms of Scotland, colloquially called the Lion Rampant, is the coat of arms historically used as arms of dominion by the monarchs of the Kingdom of Scotland, and later by monarchs of Great Britain and the United Kingdom. The coat of arms, or elements from it, are also used in heraldry to symbolise Scotland in general. The arms consist of a red lion surrounded by a red double border decorated with fleurs-de-lis, all on a gold background. The blazon, or heraldic description, is: Or a lion rampant Gules armed and langued Azure within a double tressure flory-counter-flory of the second.
In heraldic blazon, a chief is a charge on a coat of arms that takes the form of a band running horizontally across the top edge of the shield. Writers disagree in how much of the shield's surface is to be covered by the chief, ranging from one-fourth to one-third. The former is more likely if the chief is uncharged, that is, if it does not have other objects placed on it. If charged, the chief is typically wider to allow room for the objects drawn there.
Impalement is a heraldic practice in which two coats of arms are combined in one shield to denote a union. The impaled shield is bisected in pale, that is by a vertical line, with each half of the shield displaying one coat of arms. Most often the practice is used to denote the union of a husband and wife in marriage, but impalement is also used to display unions with an ecclesiastical office, academic position, government office, or mystical union.
The coat of arms of Portugal is the main heraldic insignia of Portugal. The present model was officially adopted on 30 June 1911, along with the present model of the Flag of Portugal. It is based on the coat of arms used by the Kingdom of Portugal since the Middle Ages. The coat of arms of Portugal is popularly referred as the Quinas.
Portuguese heraldry encompasses the modern and historic traditions of heraldry in Portugal and the Portuguese Empire. Portuguese heraldry is part of the larger Iberian tradition of heraldry, one of the major schools of heraldic tradition, and grants coats of arms to individuals, cities, Portuguese colonies, and other institutions. Heraldry has been practiced in Portugal at least since the 12th century, however it only became standardized and popularized in the 16th century, during the reign of King Manuel I of Portugal, who created the first heraldic ordinances in the country. Like in other Iberian heraldic traditions, the use of quartering and augmentations of honor is highly representative of Portuguese heraldry, but unlike in any other Iberian traditions, the use of heraldic crests is highly popular.
In English law, baron and feme is a phrase used for husband and wife, in relation to each other, who were accounted as one person by coverture. Hence, by the old law of evidence, the one party was excluded from giving evidence for or against the other in civil questions, and a relic of this is still preserved in criminal law.
In heraldry, a bordure is a band of contrasting tincture forming a border around the edge of a shield, traditionally one-sixth as wide as the shield itself. It is sometimes reckoned as an ordinary and sometimes as a subordinary.
The coat of arms of the City of Bradford Metropolitan District Council was granted in 1976. The council is the local authority for the district of Bradford, West Yorkshire, England. The coat of arms is based on those of Bradford Corporation, the local authority for the County Borough of Bradford, both of which were abolished in 1974.
In heraldry and heraldic vexillology, a blazon is a formal description of a coat of arms, flag or similar emblem, from which the reader can reconstruct the appropriate image. The verb to blazon means to create such a description. The visual depiction of a coat of arms or flag has traditionally had considerable latitude in design, but a verbal blazon specifies the essentially distinctive elements. A coat of arms or flag is therefore primarily defined not by a picture but rather by the wording of its blazon. Blazon is also the specialized language in which a blazon is written, and, as a verb, the act of writing such a description. Blazonry is the art, craft or practice of creating a blazon. The language employed in blazonry has its own vocabulary, grammar and syntax, which becomes essential for comprehension when blazoning a complex coat of arms.
Dexter and sinister are terms used in heraldry to refer to specific locations in an escutcheon bearing a coat of arms, and to the other elements of an achievement. Dexter indicates the right-hand side of the shield, as regarded by the bearer, i.e. the bearer's proper right, and to the left as seen by the viewer. Sinister indicates the left-hand side as regarded by the bearer – the bearer's proper left, and to the right as seen by the viewer. In vexillology, the equivalent terms are hoist and fly.
In heraldry, an orle is a subordinary consisting of a narrow band occupying the inward half of where a bordure would be, following the exact outline of the shield but within it, showing the field between the outer edge of the orle and the edge of the shield.
