The two main devices (symbols) in the Iver blazon are the lion and fesse. 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.
The art of heraldry would be significantly poorer if we were without the lion in all its forms. Most general works on Heraldry devote at least one chapter solely to this magnificent creature and its multifarious depictions 5A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P172 6Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 63 7Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P140. Some of the earliest known examples of heraldry, dating right back to the knighting of Geoffrey of Anjou in 1127, where he is shown with six such beasts upon his shield 8A Treatise on Heraldry, J. Woodward, W & A.K Johnston, Edinburgh & London, 1896, P45 .The great authority on heraldic symbology, Wade, points out the high place that the lion holds in heraldry, “as the emblem of deathless courage” 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P60, a sentiment echoed equally today.
The fesse (also found as fess) is one of the major ordinaries to found in heraldry, being a bold, broad, horizontal band across the centre of the shield. It may originally have arisen from the planks of which a wooden shield can be constructed, the centremost plank being painted a different colour 10A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Fesse. It is instantly recognisable as a symbol, for example the arms of COLEVILLE granted during the reign of Hery III are simply or, a fesse gules. With this clear association with the construction of the shield itself, Wade believes that the fesse can be taken to be associated with the military, as a “girdle of honour”.
