The two main devices (symbols) in the Kyan blazon are the fish and antique Irish crown. The main tincture (color) is gules.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P52. Although it may look like a French word it is normally pronounced with a hard “g” and may be derived either from the Latin gula (throat) or Arabic gule (rose).3A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P154
Fish in great variety abound in Heraldry, many different species inhabit coats of arms 4Understanding 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 5A 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”, 6Boutell’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”.
Crowns are frequently observed in Heraldry 7Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P184, but we should not make the mistake of assuming that these are always on Royal arms 8The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P138. Many of the orders of nobility across Europe were entitled to wear crowns and coronets, Dukes, Earls, Viscounts and Barons in England each had their own distinctive headwear 9A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P350. The antique irish crown is an example of this. It may also be the case that a crown is added to an existing coat of arms as an augmentation in recognition of some service to a King 10Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 187.
