The four main devices (symbols) in the Hillary blazon are the chequy, fesse, mullet and fleur-de-lis. 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.
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 6A 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” 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
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 8A 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” 9The 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 10A 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”.
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.
