The main device (symbol) in the Azulewicz blazon is the arrow. The two main tinctures (colors) are gules and argent.
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”1The 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 2Understanding 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.3A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P77.
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
