The four main devices (symbols) in the Kyd blazon are the mullet, crescent, tree and buglehorn. The three main tinctures (colors) are vert, azure and argent .
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” 1. 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 2. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 3. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
The bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 4. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 5.
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) 6. In a sketch or drawing it is represented by plain, unmarked paper 7.
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” 8. 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 9. 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” 10.
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 11xz`, 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 12. 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” 13.
Amongst the natural objects depicted on a coat of arms, trees feature frequently, either in whole or as individual branches and leaves. 14. Sometimes the species or the part of tree was chosen as an allusion to the name of the bearer, as in Argent three tree stumps (also known as stocks) sable” for Blackstock 15 Trees of course had long been venerated and its use in a coat of arms may have represented some association with the god Thor 16
