The main device (symbol) in the Aldaine blazon is the pile. 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 pile was originally quite a simple shape, being a triangle reaching from the top of the shield down to a point near the lower centre 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Pile. A clear example being that of CHANDOS awarded in 1337, Or a pile gules. There is some argument as to the origin, Wade suggests some similarity with the meaning of “pile” in construction (a foundation) and hence that the shape could be adopted by those who have demonstrated some ability in the building trade 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P48. An earlier writer, Guillim, perhaps more plausibly suggested that the shape echoes those of a pennant or triangular flag 8A Display of Heraldry, J. Guillim, Blome, London, 1679, P52 The shape is quite distinctive however and became popular, leading to many embellishments to distinguish it from its close fellows, with multiple piles meeting at various points, starting from various edges and with additional decoration, leading to potentially quite complex descriptions!
