The four main devices (symbols) in the Impey blazon are the leopard’s face, cinquefoil, crescent and unicorn. The three main tinctures (colors) are gules, or and vert .
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.
The deep green colour that is so often observed in heraldry is more properly known as vert. According to Wade, the use of this colour signifies “Hope and Joy”, but may also represent, rather delightfully, “Loyalty in Love” 7. It has other names also, the French call it sinople, perhaps after a town in Asia Minor from where the best green die materials could be found 8. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 9. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
The leopard’s face (sometimes, incorrectly referred to as a leopard’s head occurs very frequently in heraldry 10. Early heraldic artists tended to treat lions and leopards as the same animal, but during the development of British Heraldry the heads of the two creatures have adopted separate, and more realistic forms. Wade would have us associate leopards with warriors, especially those who overcome ”hazardous things by force and courage” 11
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 12. The cinquefoil is also of this type, being drawn, at least a little, realistically and often to very pleasing effect. It is shown as five-petalled flower, each petal quite rounded but with a distinct tip. It is sometimes pierced with a hole in the centre and usually appears on its own, without any leaves. 13 It has no fixed colour but can appear in any of the available heraldic tinctures.
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 14xz`, and the crescent Is a typical example of this, and can appear in any of the main heraldic tinctures. Some common is this device that there are special names for its appearance in various orientations – whilst it lies normally with points upward, the decrescent points to the sinister side, and the increscent to the dexter 15. The allusion, obviously is to the shape of the moon in the sky (indeed, the French have a version “figuré” which includes a face!) and has been said to signify both “honour by the sovereign” and “hope of greater glory” 16.
