The four main devices (symbols) in the Lower blazon are the rose, chevron, unicorn and oak leaf. The two main tinctures (colors) are sable and argent.
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.
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P262. The rose is also of this type, being drawn, at least a little, realistically and often to very pleasing effect. It has long been present in English heraldry, and as a badge and symbol played an enormous in English history throughout the conflict between rival dynasties known as the War of the Roses. In addition to these familial uses, Wade suggests that red roses signify “beauty and grace” and the white represents “love and faith”. 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P132-133
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.
In the mediaeval period there was no real percieved difference between real and mythical animals, after all, much of the world remained unknown and who was to say what strange and magical creatures existed in distant lands? As heraldry developed a whole menagerie of imagined creatures 11Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P164 came into being, and their various representations became more or less standardised in form and appearance. The unicorn is an intresting example that is still part of our own mythology today. The unicorn as illustrated on even the most ancient coat of arms is still instantly recognisable to us today, and shares many of the same poses that both lions and horses can be found in. 12A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Unicorn. Wade, the 18th century heraldic writer suggested that were adopted as symbols because of “its virtue, courage and strength”. 13The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P85
