The two main devices (symbols) in the Laycock blazon are the cock and chevron. The two main tinctures (colors) are argent and sable.
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) 1Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 2A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
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 3A 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 4Boutell’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 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
The cock, and other members of its avian family are often found in coats of arms, although telling them apart simply from their images can sometimes be a challenge! Many times the precise choice of species arises as a play on words on the family name, sometimes now lost in history. 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Cock The cock itself, Wade points out is a “bird of great courage” and might be used as a symbol of “watchfullness”, being the herald of the dawn. 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P80
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 8A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.9The 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” 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
