The four main devices (symbols) in the Dallas blazon are the bend, fess, mullet and crescent. The three main tinctures (colors) are gules, argent and azure .
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”1. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 2. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.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 bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 6. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 7.
The bend is a distinctive part of the shield, frequently occuring and clearly visible from a distance – it is a broad band running from top left to bottom right 8. Indeed, so important is the bend that it was the subject of one of the earliest cases before the English Court of Chivalry; the famous case of 1390, Scrope vs Grosvenor had to decide which family were the rightful owners of Azure, a bend or (A blue shield, with yellow bend). 9. The bend is held in high honour and may signify “defence or protection” and often borne by those of high military rank 10.
The fesse (also found as fess) is one of the major ordinaries to found in heraldry, being a bold, broad, horizontal band across the centre of the shield. It may originally have arisen from the planks of which a wooden shield can be constructed, the centremost plank being painted a different colour 11. It is instantly recognisable as a symbol, for example the arms of COLEVILLE granted during the reign of Hery III are simply or, a fesse gules. With this clear association with the construction of the shield itself, Wade believes that the fesse can be taken to be associated with the military, as a “girdle of honour”.
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” 12. 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 13. 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” 14.
