The main device (symbol) in the Ableshall blazon is the fess. The two main tinctures (colors) are gules and or.
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.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.4. Along with, argent, or silver it forms the two “metals” of heraldry – one of the guidelines of heraldic design is that silver objects should not be placed upon gold fields and vice versa 5. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.6.
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 7. 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”.
