The main device (symbol) in the Pielesz blazon is the sword. The main tincture (color) is gules.
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.
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 4Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 89. Indeed, the sheer variety of different swords 5A 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! If a charge is described just as a simple sword then it will have a straight blade and cross handle, that may be of a different colour, and, unless specified, points upwards. Wade, quoting the earlier writer Guillim, signifies the use of the sword as representing “Government and Justice”.
