The main device (symbol) in the Fiedler blazon is the quatrefoil. The three main tinctures (colors) are or, azure and vert .
Or is the heraldic metal Gold, often shown as a bold, bright yellow colour. It is said to show “Generosity and elevation of the mind” 1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35. Later heralds, of a more poetic nature liked to refer to it as Topaz, after the gemstone, and, for obvious reasons associated it with the Sun 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 3A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P76-77.
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” 4Boutell’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 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P150.
The deep green colour that is so often observed in heraldry is more properly known as vert. According to Wade, the use of this colour signifies “Hope and Joy”, but may also represent, rather delightfully, “Loyalty in Love” 6The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. It has other names also, the French call it sinople, perhaps after a town in Asia Minor from where the best green die materials could be found 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Vert. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 8Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 27. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 9A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P262. Like its close heraldic relative the cinquefoil, the quatrefoil is a rather sytlised flower showing four rounded petals, usually pierced by a circle at the centre.
