The main device (symbol) in the Alant blazon is the fish. The three main tinctures (colors) are azure, or and argent .
Azure is the heraldic colour blue, usually quite a deep, dark shade of the colour (there is a lighter blue that sometimes occurs, known as celestial azure). If colour printing is not available then it can be represented by closely spaced horizontal lines in a scheme known as “hatching” 1Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. The word is thought to originate from the Arabic lazura and it represents the colour of the eastern sky. It is also said to be the colour associated by the Catholic Church with the Virgin Mary and hence of particular significance 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P150.
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.
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) 6Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
Fish in great variety abound in Heraldry, many different species inhabit coats of arms 8Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P150, although truth be told many of the actual images are sometimes indistinguishable, being shown as a stylised, and easily recognised “trout” shape 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P137 that a child might draw. The actual name used in the coat of arms may be some play-on-words or allusion to the family name, as in the famous arms of the de Lucy family, being “Gules, three lucies or”, 10Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 79 this being an ancient name for the fish we call today a “pike”.
