The three main devices (symbols) in the Korwin blazon are the bird bolt, tree trunk and ring. The two main tinctures (colors) are gules and sable.
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.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. Later writers associated it with the precious stone ruby and the metal iron 3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53, perhaps because of the red glow of iron in the heat of the blacksmith’s forge.
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 4A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Sable. 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 5Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 6The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
Given the martial nature of the origins of Heraldry, in the identification of knights and men-at-arms it can come as no surprise that mediaeval weaponry of all types are frequently to be found in a coat of arms 7Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 89. Indeed, the sheer variety of different swords 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P302 can be bewildering and expaining the difference between a scimitar and a falchion is perhaps best left to the expert! Even so, the bird bolt is an important symbol in heraldry, it is a special form of arrow head. 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Bird bolt
Amongst the natural objects depicted on a coat of arms, trees feature frequently, either in whole or as individual branches and leaves. 10A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P94, 262, 407. 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 11A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P309 Trees of course had long been venerated and its use in a coat of arms may have represented some association with the god Thor 12The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P112
The most common form of household jewelery in heraldry is the ring or gem ring, shown with a jewel which may have a different colour. 13A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:ring Wade, incorrectly terms the annulet a finger ring, but assigns the meaning of “fidelity” to it – more properly this meaning belongs to the gem ring. 14The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P94
