The court official who actually voiced the monarch's proclamations, e.g. at state occasions, at jousts and tournaments; also, the officer of the College of *Arms who decided who was entitled to arms. Heralds were also important on the occasion of a judicial duel. For instance, if the battle between two knights concerned treason, heralds were positioned so as to have a clear view and be ready to act if need be, e.g. if rules were infringed. As a reward, heralds took possession of all the weapons and armour left in the field, broken or whole, of both men. The lists and barriers were given to the marshal who had overseen the event.-
