The main device (symbol) in the Achefield blazon is the leopard’s face. 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 leopard’s face (sometimes, incorrectly referred to as a leopard’s head occurs very frequently in heraldry 6A 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” 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P65
