The main device (symbol) in the Poraj blazon is the rose. 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.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”3The 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 4Understanding 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).5A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P154
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P262. The rose is also of this type, being drawn, at least a little, realistically and often to very pleasing effect. It has long been present in English heraldry, and as a badge and symbol played an enormous in English history throughout the conflict between rival dynasties known as the War of the Roses. In addition to these familial uses, Wade suggests that red roses signify “beauty and grace” and the white represents “love and faith”. 7The Symbolisms of Heraldry, W.
