The main device (symbol) in the Kur blazon is the cock. The two main tinctures (colors) are gules and argent.
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
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 cock, and other members of its avian family are often found in coats of arms, although telling them apart simply from their images can sometimes be a challenge! Many times the precise choice of species arises as a play on words on the family name, sometimes now lost in history. 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Cock The cock itself, Wade points out is a “bird of great courage” and might be used as a symbol of “watchfullness”, being the herald of the dawn. 7The Symbolisms of Heraldry, W.
