The four main devices (symbols) in the Pitt blazon are the bezant, chequy, fesse and elephant. The three main tinctures (colors) are sable, or 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.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.4Boutell’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 5A 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.6Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53.
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” 7Boutell’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 8The 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 9A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146xz`, and the bezant Is a typical example of this, and in British Heraldry always takes the tincture or. It shares the same root as the name Byzantium, being associated with the gold coin of that city and indeed, in some heraldic traditions is represented as a coin-like disk in perspective. Wade suggests that the use of this device refers to ” one who had been found worthy of trust and treasure.” 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P122
Chequy (a word with a surprising number of different spellings!) is what is known as a treatment, a repeating pattern usually used to fill the whole background of the shield with a series of alternately coloured squares 11A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Chequy. These squares are usually quite small (there should be at least 20 in total), giving the appearance of a chess board, but any combination of colours may be used. It can also be used as a patterning on some of the larger ordinaries, such as the pale and fess, in which case there are three rows of squares. Wade, an authority on heraldic meaning groups chequy with all those heraldic features that are composed of squares and believes that they represent “Constancy”, but also quotes another author Morgan, who says that they can also be associated with “wisdom…verity, probity…and equity”, and offers in evidence the existence of the common English saying that an honest man is a ”Square Dealer” 12The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P100.
The fesse (also found as fess) is one of the major ordinaries to found in heraldry, being a bold, broad, horizontal band across the centre of the shield. It may originally have arisen from the planks of which a wooden shield can be constructed, the centremost plank being painted a different colour 13A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Fesse. It is instantly recognisable as a symbol, for example the arms of COLEVILLE granted during the reign of Hery III are simply or, a fesse gules. With this clear association with the construction of the shield itself, Wade believes that the fesse can be taken to be associated with the military, as a “girdle of honour”.
