The two main devices (symbols) in the Abdy blazon are the trefoil and chevron. The two main tinctures (colors) are sable and or.
Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 1. In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 2. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 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.
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 7. The trefoil may originally been a representation of a specific plant (perhaps shamrock) but it has been used as a symbol almost since the beginning of heraldry and over time has adopted a stylised aspect. 8. Guillim believes that it signifies “perpetuity…the just man shall never wither”. 9
The chevron is one the major shapes used upon a shield, known as ordinaries. The inverted ‘V’ of the chevron is perhaps thought to have originated to represent a military scarf folded on the shield 10, or additional cross-pieces used to strengthen the shield and painted a different colour.11. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 12, possibly becuase of its resemblance to the roof truss of a house.
