Example of a gyron

A gyron is a triangular heraldic ordinary formed by two lines extending from the edge of the shield to meet at the center at a 45° angle. A shield divided into eight gyrons is called gyronny. The word gyron is derived from Old French giron, meaning 'gusset'.[1] Another term for a single gyron is esquire.[2]

The gyron rarely appears singly, but as a variation 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.[3]
