The main device (symbol) in the Beresniewicz blazon is the arrow. The two main tinctures (colors) are gules and argent.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P52. Although it may look like a French word it is normally pronounced with a hard “g” and may be derived either from the Latin gula (throat) or Arabic gule (rose).3A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P154
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.
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
