The main device (symbol) in the Greinvile blazon is the clarion. The two main tinctures (colors) are gules and or.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”1. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 2. Although it may look like a French word it is normally pronounced with a hard “g” and may be derived either from the Latin gula (throat) or Arabic gule (rose).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.
Music was as popular in the middle ages as it is today and musical instruments are frequently to be found in coats of arms 7. Sometimes these are a “play on words” such as the trumpets appearing for Trumpington 8, but sometimes just for the pleasure and ease of identification that these objects allow. The clarion is an example of this. In common with most instruments, Wade believes that the symbology of these devices is “ready for the fray”. 9
