The three main devices (symbols) in the Emery blazon are the bar nebulee, torteaux and horse. The three main tinctures (colors) are or, gules and argent .
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.1. 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 2. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.3.
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.4. The word gules is thought to come from the Arabic gule, or “red rose” 5. Later writers associated it with the precious stone ruby and the metal iron 6, perhaps because of the red glow of iron in the heat of the blacksmith’s forge.
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) 7. In a sketch or drawing it is represented by plain, unmarked paper 8.
The bar is a thin, horizontal stripe across the centre of the shield, usually in groups of two or three (any more and there would be confusion with barry, a treatment of horizontal lines of alternating colours). It is also possible to place decorative edges along bars, typically these are smaller than those found on the major ordinaries like the fess and pale, but have the same design and share the same meanings. Nebulee (sometimes nebuly is a very pleasing pattern of interlocking curves, the name refers to “clouds” as it is reminscent of their soft abstract edges.
For easy recognition of the items on a coat of arms, and hence the quick identification of the owner, bold simple shapes are best. Hence, simple geometric shapes are often used for this purpose 9 One of the simplest such shapes is the plain circle, known to heralds as the roundle. 10 So popular is this charge that a shorthand has arisen for roundles of a particular colour and torteau is a roundle gules, or red. (We must be careful however not to confuse this with the word in French heraldry, in which torteau means roundle and must have the colour specified.) Most authorities agree that the English usage signifies the “Manchet cake” or communion wafer and thus is a symbol of religious allegiance.
In the mediaeval period there was no real percieved difference between real and mythical animals, after all, much of the world remained unknown and who was to say what strange and magical creatures existed in distant lands? Nevertheless, real animals 11 are perhaps one of the most common sights on coats of arms, especially animals of European origin. The horse Is a typical example of these.
