The three main devices (symbols) in the Pott blazon are the trefoil, barry and chevron. The two main tinctures (colors) are azure and or.
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 1A 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” 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.3Boutell’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 4A 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.5Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53.
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 trefoil may originally been a representation of a specific plant (perhaps shamrock) but it has been used as a symbol almost since the beginning of heraldry and over time has adopted a stylised aspect. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Trefoil. Guillim believes that it signifies “perpetuity…the just man shall never wither”. 8A Display of Heraldry, J. Guillim, Blome, London, 1679, P109
When the field of the shield is filled with alternately coloured horizontal lines, this is known as barry, obviously because it is like having many separate bars across the field 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Barry. Such shields have great clarity from a distance, those awarded by Henry III of England to Richard de Grey were, for example, Barry argent and azure, simple blue and white horizontal stripes. According to Wade, there was no specific meaning to be attached to barry itself, but it affords the opportunity to display at equal importance two colours that may themselves have specific meanings 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P55.
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 11A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.12The 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” 13The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
