The main device (symbol) in the Czewoja blazon is the horseshoe. The two main tinctures (colors) are azure and argent.
The bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 1A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Azure. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
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) 3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 4A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
Although we expect to find fierce creatures and fearsome weapons depicted in a coat of arms this is not always the case – sometimes simple household objects are used 5A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P281. The horseshoe is a typical example of this. Sometimes these objects were chosen for the familiarity they would have for the obsever, helping them identify the owner. 6Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 100. In addition, the horseshoe, which is one the earliest symbols found in heraldry 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Horse-shoe can be seen as a “safeguard against evil spirits” and may still be found nailed above doorways today. 8The Symbolisms of Heraldry, W.
