The main device (symbol) in the Oksza blazon is the axe. 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.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.
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. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 5A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
The Axe appears in many forms in heraldic art, coming from both the martial and the craft traditions, indeed someone today would have a hard time telling their common hatchet from a turner’s axe, but it is likely that those in the middle ages were more familiar with each. 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Axe Obviously the axe from a craft tradition may symbolise the holder being a practitioner of that craft, but the axes from a martial background are suggested by Wade to indicate the “execution of military duty”. 7The Symbolisms of Heraldry, W.
