The two main devices (symbols) in the Abris blazon are the rowel and chevron. 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 word spur as a noun indicates a spike on the back of horseman’s boot to goad a horse into action, and for the same reason as a verb it signifies “encouraging action”. Because of this, Guillim assigns the meaning “press onward” to the prescence of a spur in a coat of arms. 6 It can be depicted either as the full item, with connections to the boot, or just as the star-shaped spur rowel which contains the spikes. 7
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 8, or additional cross-pieces used to strengthen the shield and painted a different colour.9. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 10, possibly becuase of its resemblance to the roof truss of a house.
