The three main devices (symbols) in the Baumuller blazon are the wall, estoile and ostrich feathers. 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.
Architectural items, from individual components to entire buildings 5Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 92 feature frequently as charges In a coat of arms. Not surprisingly, considering the times from which many arms date, fortifications are common. The wall Is a typical example of an object from the world of architecture adopted, occaisionally on its own but more often as an adjunt of a tower. More rarely, a single Wall stone is illustrated.
There were of course many widely recognised symbols that existed long before the advent of heraldry and it should be no surprise that some of these were adopted as charge in coats of arms 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P301. The estoile is a typical example, reflecting the stars in the sky and represented with six wavy points, often with a little shading to give it some depth. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Estoile. The ancient writer Guillim assigns these symbols as the emblems of God’s goodness”. 8A Display of Heraldry, J. Guillim, Blome, London, 1679, P77
The feather, especially that of the ostrich appears with great regularity in the crests of a full achievement of arms, typically in the shape of a plume. Wade associates this device with “willing obedience and serenity of mind”. 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P74 They are much less common on the shield itself, unless part of an arrow, which may be feathered of a different colour, or a quill pen. 10A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Feathers
