The two main devices (symbols) in the Jowers blazon are the sun and bezant. The two main tinctures (colors) are azure and or.
Azure is the heraldic colour blue, usually quite a deep, dark shade of the colour (there is a lighter blue that sometimes occurs, known as celestial azure). If colour printing is not available then it can be represented by closely spaced horizontal lines in a scheme known as “hatching” 1Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. The word is thought to originate from the Arabic lazura and it represents the colour of the eastern sky. It is also said to be the colour associated by the Catholic Church with the Virgin Mary and hence of particular significance 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P150.
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.
The sun was long used as a potent symbol before the advent of heraldry and brought some of that existing meaning with it. In conventional heraldry it is normally borne in its splendour, that is with a face and a large number of alternating straight and wavy rays. 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Sun It can also be seen issuing from behind clouds, and in some cases a demi or half sun coming from the base, reflecting either the dawn, or perhaps as it appears in the arms of WESTWORTH, with the sunset. 7A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P296
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 8A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146xz`, and the bezant Is a typical example of this, and in British Heraldry always takes the tincture or. It shares the same root as the name Byzantium, being associated with the gold coin of that city and indeed, in some heraldic traditions is represented as a coin-like disk in perspective. Wade suggests that the use of this device refers to ” one who had been found worthy of trust and treasure.” 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P122
