Agyron is a triangularheraldic ordinary having an angle at thefess point and the opposite side at the edge of the escutcheon. A shield divided into gyrons is calledgyronny, the default is typically of eight if no number of gyrons is specified. The wordgyron is derived fromOld Frenchgiron, meaning 'gusset'.[1] When a single gyron extends across so the tip touches the edge of the coat of arms, forming a square, it is called anesquire.[2][3]
The gyron rarely appears singly, but as avariation of the field, gyronny coats appear frequently. These most often appear as eight roughly equal parts, but occasionally a coat gyronny of six, ten, twelve or more parts may be specified.[4]

^Robson, Thomas (1830).The British herald, or Cabinet of armorial bearings of the nobility & gentry of Great Britain & Ireland.Esquire, equire, or squire, by Edmondson considered the same as the gyron, which must be wrong, because the gyron only extends to the centre fesse point; whereas the esquire, though of the same shape, runs across the whole field.
