The main device (symbol) in the Doney blazon is the chief. The two main tinctures (colors) are vert and ermine.
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” 1. 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 2. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 3. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
Ermine is a very ancient pattern, and distinctive to observe. It was borne alone by John de Monfort, the Earl of Richmond and Duke of Brittany in the late 14th century 4 It has a long association with royalty and the nobility in general and hence represents “Dignity” wherever it is found 5. The ermine pattern is white with, typically, a three dots and a dart grouping representing the tail of the furred creature.6. The ermine spot is sometimes found alone as a special charge on the shield.
The chief is an area across the top of the field 7. It appears in many different forms and can itself be charged with other charges and ordinaries, 8, being treated almost as if it were a completely separate area. In its simplest form it can be clearly identified. Early examples include the award by Henry III of England to the knight Robert de MORTEYN BRETON of Ermine, a chief gules.
