Or is the heraldic metal Gold, often shown as a bold, bright yellow colour. It is said to show “Generosity and elevation of the mind” 1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35. Later heralds, of a more poetic nature liked to refer to it as Topaz, after the gemstone, and, for obvious reasons associated it with the Sun 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 3A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P76-77.
Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 4A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Sable. In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 5Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 6The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
The mascle is a close relative of the lozenge or diamond shape, but with the centre cut away revealing the background underneath. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Mascle. Guillim, writing in the 17th century reckoned the mascle to represent the mesh of a net, being the biblical symbol for “persuasion, whereby men are induced to virtue and verity”. 8A Display of Heraldry, J. Guillim, Blome, London, 1679, P234
The chevron is one the major shapes used upon a shield, known as ordinaries. The inverted ‘V’ of the chevron is perhaps thought to have originated to represent a military scarf folded on the shield 9A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.10The Pursuivant of Arms, J. R. Planche, Hardwicke, London 1859. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 11The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
The chief is an area across the top of the field 12Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 40. It appears in many different forms and can itself be charged with other charges and ordinaries, 13A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Chief, being treated almost as if it were a completely separate area. In its simplest form it can be clearly identified. Early examples include the award by Henry III of England to the knight Robert de MORTEYN BRETON of Ermine, a chief gules.
