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” 1. 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 2. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 3.
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” 4. 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 5.
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” 6. 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 7. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 8. 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 9. 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.
