The four main devices (symbols) in the Ewing blazon are the moon, mullet, chevron and sun. The three main tinctures (colors) are azure, gules and argent .
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.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”3The 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 4Understanding 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).5A 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) 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.
It should come as no surprise that items from the natural world are frequently adopted for use in the coat of arms 8A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P294. Celestial objects and natural phenomena have been given simple, easily identified representations. The moon Is typical of charges derived from natural objects, and being emblematic of “serene power the mundane” 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P106. It can be shown in various phases, known as incresent (facing right), decrescent (facing left), or if full then with a human face. 10A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:moon
The heraldic mullet, not to be confused with the fish of that name, is shown as a regular, five pointed star. This was originally, not an astronomical object, but represented the spur on a horseman’s boot, especially when peirced, with a small circular hole in the centre it represents a type of spur known as a “rowel” 11Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 97. A clear example can be found in the arms of Harpendene, argent, a mullet pierced gules. The ancient writer Guillim associated such spurs in gold as belonging to the Knight, and the silver to their esquires 12A Display of Heraldry, J. Guillim, Blome, London, 1679, P107. In later years, Wade linked this five pointed star with the true celestial object, the estoile and termed it a “falling star”, symbolising a “divine quality bestowed from above” 13The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P105.
The chevron is one the major shapes used upon a shield, known as ordinaries. The inverted ‘V’ of the chevron is perhaps thought to have originated to represent a military scarf folded on the shield 14A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.15The Pursuivant of Arms, J. R. Planche, Hardwicke, London 1859. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 16The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
