In heraldic blazon, a chief is a charge on a coat of arms that takes the form of a band running horizontally across the top edge of the shield. Writers disagree in how much of the shield's surface is to be covered by the chief, ranging from one-fourth to one-third. The former is more likely if the chief is uncharged, that is, if it does not have other objects placed on it. If charged, the chief is typically wider to allow room for the objects drawn there. The chief is one of the ordinaries in heraldry, along with the bend, chevron, fess, and pale. There are several other ordinaries and sub-ordinaries. Variations of chief The chief may bear charges and may also be subject to variations of the partition lines. It cannot, however, be cotised. The chief may be combined with another ordinary, such as a pale or a saltire, but is almost never surmounted by another ordinary. The chief will normally be superimposed over a bordure, orle and tressure, if they share the same shield. Other variations In some medieval and Renaissance drawings of coats of arms, the chief is drawn even deeper, so that it fills almost all the top half of the shield. In some cases, it is drawn so wide that it will look as though the shield is divided party per fess. There is a diminutive version of the chief, called a comble, but this does not occur in English and Scottish heraldry. A chief triangular can be found in French and English armory. This ordinary begins in the corners and extends to a point that is one quarter to one third the way down the shield. It is a complex line division variant of a chief. A chief enarched is drawn with a concave arch. There is also a double-arched version of a chief. The chief can be used as a mark of cadency, in order to difference the coat of arms in a minor line of a family, though this is rare and practically confined to cases in which a system of bordures is the usual method of showing cadency and the undifferenced coat of the family already has a bordure. In civic heraldry, a chief of allegiance may be added to the top of the shield, particularly in German heraldry. This is a form of the ruling state's armory compressed into the
