The three main devices (symbols) in the Knott blazon are the chevron, crescent and unicorn. The three main tinctures (colors) are or, azure and guttee dor .
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.1Boutell’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 2A 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.3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53.
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 4A 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” 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
The gutte or goutte is an elongated tear-drop shape with wavy sides and usually appears in large number spread evenly across the field. 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Gouttes Some frequently do they occur that special names have arisen for the various colours, guttee d’or or gutte aure being or (gold) for who would not delight in a field strewn with drops of gold!
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 7A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.8The 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” 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
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 10A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146xz`, and the crescent Is a typical example of this, and can appear in any of the main heraldic tinctures. Some common is this device that there are special names for its appearance in various orientations – whilst it lies normally with points upward, the decrescent points to the sinister side, and the increscent to the dexter 11A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Moon. The allusion, obviously is to the shape of the moon in the sky (indeed, the French have a version “figuré” which includes a face!) and has been said to signify both “honour by the sovereign” and “hope of greater glory” 12The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P106.
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 13Understanding 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. 14A 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”. 15The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P85
