The three main devices (symbols) in the Horner blazon are the buglehorn, talbot and cross formee. The two main tinctures (colors) are sable and argent.
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 1A 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 2Boutell’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 3The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
Argent is the heraldic metal Silver and is usually shown as very pure white. It is also known more poetically as pearl, moon (or luna) 4Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 5A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
The hunting horn, or bugle horn has a distinctive shape, being curved almost into a semi-circle, it can be decorated with bands of a different colour and typically hangs from a string, also coloured. 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:hunting horn. Apart from its obvious reference to the pursuit of hunting, it has also been used in allusion to the name of the holderr (HUNTER of Hunterston) and Woowward suggests it is also associated with those who have rights or obligations to the forest. 7A Treatise on Heraldry, J. Woodward, W & A.K Johnston, Edinburgh & London, 1896, P400
Many breeds of dog appear in coats of arms, reflecting their status as man’s closet companion. The talbot is a hunting dog akin to a terrier, and usually illustrated in a lifelike style and eager pose. 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Dog In common with the other heraldic dogs, Wade suggests that their presence should suggest “courage, vigilance and loyal fidelity”. 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P68 Others might say we need look no further than a pleasure in the hunt and the affection for this sturdy breed.
No other symbol appearing in heraldry is subject to as much variation as the cross 10Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 47. Mediaeval Europe was a deeply religious and Christian and many of the nobility wanted to show their devotion by adopting the symbol of the cross as part of the arms. Since no two arms could be identical there arose many variants of the cross, typically involving patterning along the edges 11Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P67, or fanciful, decorative endings to the arms of the cross 12A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P128. The cross formee is typical of these, (also known as a cross pattee) it has arms which broaden out in smooth curves towards the ends.
