The main device (symbol) in the Pomesworth blazon is the pale. The two main tinctures (colors) are azure and argent.
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.
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) 3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 4A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
The Pale is one of the major, so called ordinaries, significant objects that extend across the entire field of the shield. The pale being a broad vertical band up the centre of the shield 5A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Pale. In origin, the word probably has its roots in the same place as palisade, a defensive wall made of closely space upright timbers. Indeed, it is possible that the original “pales” arose where a wooden shield was constructed of vertical planks painted in different hues 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, Chapter 1. This is perhaps why Wade, a writer on Heraldic Symbology suggested that denotes “military strength and fortitude” 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P47.
