The two main devices (symbols) in the Hoyle blazon are the lion and mullet. The three main tinctures (colors) are argent, sable and or .
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) 1. In a sketch or drawing it is represented by plain, unmarked paper 2.
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 3. 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 4. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 5.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.6. 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 7. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.8.
The art of heraldry would be significantly poorer if we were without the lion in all its forms. Most general works on Heraldry devote at least one chapter solely to this magnificent creature and its multifarious depictions 9 10 11. Some of the earliest known examples of heraldry, dating right back to the knighting of Geoffrey of Anjou in 1127, where he is shown with six such beasts upon his shield 12 .The great authority on heraldic symbology, Wade, points out the high place that the lion holds in heraldry, “as the emblem of deathless courage” 13, a sentiment echoed equally today.
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” 14. 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 15. 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” 16.
