The three main devices (symbols) in the Hair blazon are the thistle, bars and lion. The three main tinctures (colors) are argent, or and gules .
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.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.3. 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 4. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.5.
The bold red colour on a heraldic shield is known as gules. It has a long history within heraldry, it is known that one of those who besieged the scottish castle of Carlaverock in 1300 was the French knight Euremions de la Brette who had as his arms a simple red shield.6. The word gules is thought to come from the Arabic gule, or “red rose” 7. Later writers associated it with the precious stone ruby and the metal iron 8, perhaps because of the red glow of iron in the heat of the blacksmith’s forge.
The thistle as a symbol is inevitably associated with Scotland, although more often as a badge rather than appearing as an item upon a shield. 9 Despite its prickly reputation the images of this flowering plant are very striking and they are usually shown with leaves to either side in quite an accurate representation. 10
The bar is a thin, horizontal stripe across the centre of the shield 11, usually in groups of two or three (any more and there would be confusion with barry, a treatment of horizontal lines of alternating colours). Bars can be a distinctive and easily recognised device, early examples include those awarded by Henry III of England to the family MAUDYT Argent, two bars gules.
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 12 13 14. 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 15 .The great authority on heraldic symbology, Wade, points out the high place that the lion holds in heraldry, “as the emblem of deathless courage” 16, a sentiment echoed equally today.
