The three main devices (symbols) in the Keynes blazon are the bezant, bar and talbot. The three main tinctures (colors) are vair, gules and azure .
The bold red colour on a heraldic shield is known as gules. It has a long history within heraldry, it is known that one of those who besieged the scottish castle of Carlaverock in 1300 was the French knight Euremions de la Brette who had as his arms a simple red shield.1The Siege of Carlaverock, N. Harris, Nichols & Son, London, 1828, P180. The word gules is thought to come from the Arabic gule, or “red rose” 2Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 313. Later writers associated it with the precious stone ruby and the metal iron 3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53, perhaps because of the red glow of iron in the heat of the blacksmith’s forge.
The bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 4A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Azure. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
For easy recognition of the items on a coat of arms, and hence the quick identification of the owner, bold simple shapes are best. Hence, simple geometric shapes are often used for this purpose 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146xz`, and the bezant Is a typical example of this, and in British Heraldry always takes the tincture or. It shares the same root as the name Byzantium, being associated with the gold coin of that city and indeed, in some heraldic traditions is represented as a coin-like disk in perspective. Wade suggests that the use of this device refers to ” one who had been found worthy of trust and treasure.” 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P122
The bar is a thin, horizontal stripe across the centre of the shield 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Bar, usually in groups of two or three (any more and there would be confusion with barry, a treatment of horizontal lines of alternating colours). Bars can be a distinctive and easily recognised device, early examples include those awarded by Henry III of England to the family MAUDYT Argent, two bars gules.
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. 9A 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”. 10The 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.
