Choice of method should naturally be based on the desire to represent things in the most direct way and by the simplest means that are suitable to the purpose in hand, using exactly the right amount of elaboration, from the perfect simplicity demanded by a figure in perforated iron, through the varying detail of different forms of applied art, stained glass, enamel, modelling, carving, painting and engraving. There is always great charm about simple treatment that is at the same time expressive, but the right simplicity can only be reached through knowledge, and is a very different thing from the emptiness which ignorance hopes to have mistaken for it. Clearness of statement expressed by vigour of drawing, beauty of line, balance of mass and harmonious coherence of composition, are obviously essential qualities; and when to these are added suitability to environment and material, the result will be that expression of rightness which constitutes style, whatever the style may be. Heraldic accuracy is assumed as a matter of course, for heraldry that is not accurate stultifies itself. The usual grouping of an achievement was suggested, no doubt, by the method of displaying armorials in processions and other ceremonials, when the crested and mantled helmet was placed on a lance staff or some similar support, and the shield was hung below by its guige. That the grouping was also a natural one is visible in the seal of Henry IV (p. 18), especially if we imagine the figure to be seen from the opposite side. There is nothing heraldically essential in arranging the armorials in this order, for the crest may be placed in any other relation to the shield that circumstances may render preferable. When, for instance, it is undesirable to pile up the design in height the crest is placed at the side of the shield. The earliest instance of which I am aware is that of Lord Basset of Drayton, whose arms thus appeared on his stall-plate as a Knight of the Garter. In such cases it is usually most convenient to pose the crest on the true right of the shield because the swing back of the mantling serves admirably to tie up the whole design, but there is no reason why the positions should not be reversed if the lines can be made to compose satisfactorily; that is to say, it is only a matter of ornamental design and not in any way of heraldic right or wrong.
