or COAT OF ARMS, in Heraldry, a habit worn by the ancient knights over their arms, and still borne by heralds-at-arms. It was a kind of surcoat, reaching as low as the navel, open at the sides, with short sleeves, upon which were applied the armories of the knights embroidered in gold and silver, and enamelled with beaten tin, coloured black, green, red, and blue. The coats of arms were frequently open, and diversified with bands and fillets of several colours, placed alternately, and called devices, as being divided and composed of several pieces sewed together. The representation of these is still called a coat of arms. See Heraldry.
