The two main devices (symbols) in the Ketton blazon are the leopard’s face and bar. The three main tinctures (colors) are azure, or and sable .
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 1A 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” 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.3Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 27. Along with, argent, or silver it forms the two “metals” of heraldry – one of the guidelines of heraldic design is that silver objects should not be placed upon gold fields and vice versa 4A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P85. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.5Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53.
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 6A 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 7Boutell’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 8The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
The leopard’s face (sometimes, incorrectly referred to as a leopard’s head occurs very frequently in heraldry 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Lion. Early heraldic artists tended to treat lions and leopards as the same animal, but during the development of British Heraldry the heads of the two creatures have adopted separate, and more realistic forms. Wade would have us associate leopards with warriors, especially those who overcome ”hazardous things by force and courage” 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P65
The bar is a thin, horizontal stripe across the centre of the shield 11A 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.
