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.1The Siege of Carlaverock, N. Harris, Nichols & Son, London, 1828, P180. The word gules is thought to come from the Arabic gule, or “red rose” 2Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 313.

Croton, Quantum, London, 2013, P53, 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) 4Understanding Signs & Symbols – Heraldry, S. Oliver & G.
