The three main devices (symbols) in the Harlewin blazon are the apple, garb and fleur-de-lis. 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 apple, in conjunction with other fruit is said to signify “liberality, felicity and peace”. 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P132 The apple appears frequently in arms, sometimes stalked and leaved and usually gules (red). 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Apple
Europe in the middle ages was still a largely agrarian society, and the wealth of the nobility resided in their estates and land. Since most people still lived and worked on the land they would find farm implements instantly recognisable, (an important feature for a coat of arms), even if they seem obscure to us today. 7Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 86 The garb for example is an ancient word for wheatsheaf, something now more frequently seen in Inn signs than in the field! 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Garbe
The fleur-de-lys (“flower of the lily”) has a long and noble history and was a symbol associated with the royalty of France even before heraldry became widespread. 9Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 3. The Lily flower is said to represent “Purity, or whiteness of soul”10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P134 and sometimes associated with the Virgin Mary. The fleur-de-lys is also used as a small “badge”, known as a mark of cadency to show that the holder is the sixth son of the present holder of the arms 11A Complete Guide to Heraldry, A.C.
