The three main devices (symbols) in the Eady blazon are the fleur-de-lis, chevron and serpent. The three main tinctures (colors) are vert, gules 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!
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”4. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 5. Although it may look like a French word it is normally pronounced with a hard “g” and may be derived either from the Latin gula (throat) or Arabic gule (rose).6
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 7 It has a long association with royalty and the nobility in general and hence represents “Dignity” wherever it is found 8. The ermine pattern is white with, typically, a three dots and a dart grouping representing the tail of the furred creature.9. The ermine spot is sometimes found alone as a special charge on the shield.
The fleur-de-lys (“flower of the lily”) has a long and noble history and was a symbol associated with the royalty of France even before heraldry became widespread. 10. The Lily flower is said to represent “Purity, or whiteness of soul”11 and sometimes associated with the Virgin Mary. The fleur-de-lys is also used as a small “badge”, known as a mark of cadency to show that the holder is the sixth son of the present holder of the arms 12
The chevron is one the major shapes used upon a shield, known as ordinaries. The inverted ‘V’ of the chevron is perhaps thought to have originated to represent a military scarf folded on the shield 13, or additional cross-pieces used to strengthen the shield and painted a different colour.14. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 15, possibly becuase of its resemblance to the roof truss of a house.
In the mediaeval period there was no real percieved difference between real and mythical animals, after all, much of the world remained unknown and who was to say what strange and magical creatures existed in distant lands? As heraldry developed a whole menagerie of imagined creatures 16 came into being, and their various representations became more or less standardised in form and appearance. The serpent Is a typical example of a mythical creature, as real to a person of the middle ages as dogs, cats and elephants are to us today.
