The four main devices (symbols) in the Glass blazon are the fleur-de-lis, mullet, rose and mermaid. The two main tinctures (colors) are gules and argent.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”1. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 2. 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).3
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) 4. In a sketch or drawing it is represented by plain, unmarked paper 5.
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. 6. The Lily flower is said to represent “Purity, or whiteness of soul”7 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 8
The heraldic mullet, not to be confused with the fish of that name, is shown as a regular, five pointed star. This was originally, not an astronomical object, but represented the spur on a horseman’s boot, especially when peirced, with a small circular hole in the centre it represents a type of spur known as a “rowel” 9. A clear example can be found in the arms of Harpendene, argent, a mullet pierced gules. The ancient writer Guillim associated such spurs in gold as belonging to the Knight, and the silver to their esquires 10. In later years, Wade linked this five pointed star with the true celestial object, the estoile and termed it a “falling star”, symbolising a “divine quality bestowed from above” 11.
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 12. The rose is also of this type, being drawn, at least a little, realistically and often to very pleasing effect. It has long been present in English heraldry, and as a badge and symbol played an enormous in English history throughout the conflict between rival dynasties known as the War of the Roses. In addition to these familial uses, Wade suggests that red roses signify “beauty and grace” and the white represents “love and faith”. 13
