The three main devices (symbols) in the Craigie blazon are the crescent, chevron and cornucopia. The three main tinctures (colors) are sable, argent and azure .
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.
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” 6Boutell’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 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P150.
For easy recognition of the items on a coat of arms, and hence the quick identification of the owner, bold simple shapes are best. Hence, simple geometric shapes are often used for this purpose 8A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146xz`, and the crescent Is a typical example of this, and can appear in any of the main heraldic tinctures. Some common is this device that there are special names for its appearance in various orientations – whilst it lies normally with points upward, the decrescent points to the sinister side, and the increscent to the dexter 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Moon. The allusion, obviously is to the shape of the moon in the sky (indeed, the French have a version “figuré” which includes a face!) and has been said to signify both “honour by the sovereign” and “hope of greater glory” 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P106.
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 11A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.12The 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” 13The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
There are occaisional examples of mythical beings or objects illustrated in a coat of arms, either as an image upon the shield, or as a supporter, and the Cornucopia is an example of this. Any meaning must really be ascribed from the charateristics of that object, nothing additional is added through their heraldic use. 14The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P124 It is illustrated in conventional form as the horn of plenty. 15A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Cornucopia
