The two main devices (symbols) in the Creston blazon are the saltire engrailed and mullet. The three main tinctures (colors) are or, gules and azure .
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.
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 7. 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” 8.
The saltire, whilst frequently associated with Scotland is actually a widely used and popular ordinary found throughout all of British Heraldry, perhaps because of its cross-like form 9. In order to allow for clear differences between similar arms, heralds designed a series of decorative edges, not all of them are appropriate for the saltire (because of the interior angles) but those are suitable can be very effective artistically. The pattern engrailed works well here. It is a series of scalloped indentations with the points facing outwards – and should not be confused with invected, which has the points facing inwards! Wade believes that both of these indented forms represent “earth or land”, and one perhaps can indeed see the furrowed earth embodied in them.
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” 10. 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 11. 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” 12.
