Gyron

Inglese

PO:CON

gherone

is a triangular figure covering generally the eighth part of the shield, but is sometimes diminished into a sixteenth part, when it is multiplied and carried round the field. This figure proceeds either from the dexter or sinister side of the shield to the centre, forming a rectangular though very irregular triangle. When multiplied in the field, so as to cover it with a series of equal divisions of different colours or metals, the field is said to be gyronny of so many pieces. But every one of these must be equal
