Bruges's appointment as the first Garter King of Arms coincided with a series of moves to regulate heraldic matters. In June 1417 the king clamped down on the unauthorized wearing of coat armour. In September the duke of Clarence ruled on matters of precedence between the heralds and the serjeants-at-arms. In January 1421 the English heralds held their first chapter and directed that a common seal for that office be made. Resolutions were to govern the office of arms and its members, with chapters summoned by Garter. In the same year, as part of Henry's revival of the Order of the Garter, some statutes of the order were revised and at about the same time many heraldic stall plates of former companions were set up in St. George's Chapel, Windsor. Bruges was also responsible for producing his "Bruges Garter Book" around 1430, which is the earliest known armorial of the order.
