The main device (symbol) in the Pozniak blazon is the arrow. The two main tinctures (colors) are argent and gules.
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) 1Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 2A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”3The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 4Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.5A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P77.
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 6Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 89. The regular prescence of the arrow, both singly and in groups is evidence of this. In British heraldry a lone arrow normally points downward, but in the French tradition it points upwards. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Arrow. The presence of an arrow in a coat of arms is reckoned to indicate “martial readiness” by Wade. 8The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P111
