The main device (symbol) in the Kornic blazon is the feather. The two main tinctures (colors) are gules and argent.
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.1. The word gules is thought to come from the Arabic gule, or “red rose” 2. Later writers associated it with the precious stone ruby and the metal iron 3, perhaps because of the red glow of iron in the heat of the blacksmith’s forge.
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) 4. In a sketch or drawing it is represented by plain, unmarked paper 5.
The feather, especially that of the ostrich appears with great regularity in the crests of a full achievement of arms, typically in the shape of a plume. Wade associates this device with “willing obedience and serenity of mind”. 6 They are much less common on the shield itself, unless part of an arrow, which may be feathered of a different colour, or a quill pen. 7
