The four main devices (symbols) in the Jaffray blazon are the fesse, mullet, paly and sun. The two main tinctures (colors) are sable and argent.
Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 1. In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 2. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 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 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 6. 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” 7. 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 8. 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” 9.
Play is what is known as a treatment, a regular patterning, usually over the whole background of the shield. The word comes from the pale, the major vertical stripe that appears on some shields, paly is obvious its little cousin, consisting of, typically, 6 or more vertical stripes, alternately coloured 10. The stripes can be any combination of the heraldic tinctures, an early example is that of GURNEY, being simply paly of six, or and argent. Paly can be combined with other effects, such as decorative edges on each stripe, or overlaid with other treatments such as bendy, and these can be very effective and pleasing to the eye 11.
