be treated as a subordinary in its own right as it fulfils heraldic functions not fulfilled by the quarter, and behaves according to its own special rules—as for example in the case of the canton on which baronets in the UK may display the badges of their 'rank', which is very rarely shown occupying such a large area as the upper left third of the field, and is usually much less and very often shown not as square but as a rectangle with its longer side vertical. Very occasionally a 'sinister canton' is found, on the shield's other side. Flaunches, always borne in pairs: a circular arc emerging out of each flank of the shield. Fret: interlacing bendlet, bendlet sinister and mascle. Gore: two arcs meeting in the fess point to form a triangular segment. Gyron: the lower half of a quarter cut diagonally, said to be an old charge but rare although there are modern examples (e. g. de Cluseau) Orle: A bordure separated from the outside of the shield. Like the bordure the orle takes on the shape of the shield or flag it is on. Although the orle's diminutive is the tressure, there are examples of "fillet orles" (orles narrower than usual). It is often said that an orle may not have other charges charged on it, but the Scots Public Register. When a number of charges are arranged as if on a bordure, they are said to be in orle or to form an orle of such charges. Tressure: a thinner version and hence diminutive of the orle. The most famous tressure is probably the double tressure flory counter flory in the royal coat of arms of Scotland. Tressures with other ornamentation exist, such as with maple leaves, crescents, thistles and roses. Mobile subordinaries Other subordinaries can be placed anywhere on the field. Escutcheon: a shield used as a charge. escutcheon of pretence or en surtout—When one escutcheon is borne in the centre of the coat, it is sometimes called an inescutcheon or an escutcheon of pretence or an escutcheon en surtout. Such centrally placed escutcheons usually have some particular significance. For example, in arms of dominion an inescutcheon typically shows the dynastic arms of the prince, whose possessions are shown in the quarters of the main shield; current examples include the arms of the Danish Royal Family, with an inescutcheon of the house of Oldenburg,
