The two main devices (symbols) in the Dolega blazon are the horseshoe and arrow. The two main tinctures (colors) are argent and azure.
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.
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 3A 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” 4The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
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. Cecil Wade, George Redway, London, 1898 P112
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 9Boutell’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. 10A 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. 11The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P111
