| No. 66. | No. 67. |
Should the field of any charge be divided into a single row of small squares, alternately, e.g. of a metal and a colour, as No. 66, it is Componée or Compony (sometimes written gobony): if into two such rows, as in No. 67, it is Counter Compony: but, if the field of a Shield, or the surface of any charge be divided into three, or more than three, such rows, it is Chequée or Checky; thus, the Arms of the Earl de Warenne are Chequée or and az., No. 68 (H. 3 and E. 2).
No. 68.— Shield of Arms of Earl de Warrenne, Castle Acre Priory, Norfolk.
The Law of Tinctures.—Every charge is supposed to rest upon the field of a Shield, or on the surface of some charge. It is a strict rule, that a charge of a metal must rest upon a field that is of a colour or fur; or, contrariwise, that a charge of a colour must rest on a field that is of a metal or fur,—that is, that metal be not on metal, nor colour on colour. This rule is modified in the case of varied fields, upon which may be charged a bearing of either a metal or a colour: also, a partial relaxation of the rule is conceded when one bearing is charged upon another, should the conditions of any particular case require such a concession. This rule does not apply to bordures, nor very stringently to augmentations or crests, and it is not so rigidly enforced in Foreign as in British Heraldry. There are, of course, a few exceptions, but they are not numerous, the one usually instanced as an intentional violation being the silver armorial Shield of the Crusader Kings of Jerusalem, No. 69, upon which five golden crosses are charged; the motive in this remarkable exception to an established rule being said to be to cause this Shield to be unlike that of any other potentate. What may be termed the accessories of a charge are not included in this law of tinctures: thus, a silver lion having a red tongue may be charged on a blue shield, and the red tongue may rest on the blue field of the Shield.
| No. 69.— Arms of Jerusalem. | No. 70.— Arms of Fenwick. |
Counterchanging is dividing the field of a Shield in such a manner that it is, e.g. in part of a metal and in part of a colour, and then arranging the charges in such a manner that they shall be reciprocally of the same colour and metal: thus, the shield of John Fenwick, No. 70 (R. 2) is,—per-fesse gu. and arg., six martlets, three, two, one, counterchanged; that is, the field is red in chief and silver in base, and the birds or parts of the birds on the red field are silver, and those on the silver field are red.
Diapering.—This term denotes a system of decorating plain surfaces in various ways, which was in great favour with the early heraldic artists. In the use of Diaper, which is often desirable when artistic reasons suggest its suitability, care must be taken that the decorative designs and patterns do not in any way admit of their being mistaken for charges. This diaper may be executed in low relief, subordinated to the relief of the charges; and it is not required to yield any obedience to the law of tinctures. In the Shield, [No. 68] (the original, a very noble shield, is at Castle Acre Priory, Norfolk), which is simply chequée, the Diapering may be alternately azure and or on the squares that are alternately or and azure; or the Diaper may be dark blue, or sable, or argent on the azure squares, and on the golden ones whatever the artist might consider would be most effective; but the Diaper, in this and in all other examples, must always be subordinate to the area and tincture of the field. The finest known early example of heraldic Diaper in enamel, is the Shield of William de Valence, Earl of Pembroke, in Westminster Abbey, A.D. 1296. Very beautiful early examples of Diapering have been preserved in relics of heraldic stained glass.
