The shield is the most important part of the achievement, for on it are depicted the signs and emblems of the house to which it appertains; the difference marks expressive of the cadency of the members within that house; the augmentations of honour which the Sovereign has conferred; the quarterings inherited from families which are represented, and the impalements of marriage; and it is with the shield principally that the laws of armory are concerned, for everything else is dependent upon the shield, and falls into comparative insignificance alongside of it. Let us first consider the shield itself, without reference to the charges it carries. A shield may be depicted in any fashion and after any shape that the imagination can suggest, which shape and fashion have been accepted at any time as the shape and fashion of a shield. There is no law upon the subject. The various shapes adopted in emblazonments in past ages, and used at the present time in imitation of past usage--for luckily the present period has evolved no special shield of its own--are purely the result of artistic design, and have been determined at the periods they have been used in heraldic art by no other consideration than the particular theory of design that has happened to dominate the decoration, and the means and ends of such decoration of that period. The lozenge certainly is reserved for and indicative of the achievements of the female sex, but, save for this one exception, the matter may be carried further, and arms be depicted upon a banner, a parallelogram, a square, a circle, or an oval; and even then one would be correct, for the purposes of armory, in describing such figures as shields on all occasions on which they are made the vehicles for the emblazonment of a design which properly and originally should be borne upon a shield. Let no one think that a design ceases to be a coat of arms if it is not displayed upon a shield. Many people have thought to evade the authority of the Crown as the arbiter of coat-armour, and the penalties of taxation imposed by the Revenue by using designs without depicting them upon a shield. This little deception has always been borne in mind, {61} for we find in the Royal Warrants of Queen Elizabeth commanding the Visitations that the King of Arms to whom the warrant was addressed was to "correcte, cumptrolle and refourme all mann' of armes, crests, cognizaunces and devices unlawfull or unlawfully usurped, borne or taken by any p'son or p'sons within the same p'vince cont^ary to the due order of the laws of armes, and the same to rev'se, put downe or otherwise deface at his discrecon as well in coote armors, helmes, standerd, pennons and hatchmets of tents and pavilions, as also in plate jewells, pap', parchement, wyndowes, gravestones and monuments, or elsewhere wheresoev' they be sett or placed, whether they be in shelde, schoocheon, lozenge, square, rundell or otherwise howsoev' cont^arie to the autentiq' and
