The two main devices (symbols) in the Hackford blazon are the chequy and bend nebulee. The three main tinctures (colors) are vert, or and sable .
The deep green colour that is so often observed in heraldry is more properly known as vert. According to Wade, the use of this colour signifies “Hope and Joy”, but may also represent, rather delightfully, “Loyalty in Love” 1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. It has other names also, the French call it sinople, perhaps after a town in Asia Minor from where the best green die materials could be found 2A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Vert. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 3Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 27. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
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.
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 7A 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 8Boutell’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 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
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 10A 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” 11The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P100.
The bend is a distinctive part of the shield, frequently occuring and clearly visible from a distance – it is a broad band running from top left to bottom right 12Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 39-40. It can be further distinguished by embellishing the edges. Nebulee (sometimes nebuly is a very pleasing pattern of interlocking curves, the name refers to “clouds” as it is reminscent of their soft abstract edges.
