The two main devices (symbols) in the Hazard blazon are the garb and escallop. 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.
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. 5Boutell’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! 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Garbe
The escallopoccurs often in arms, represented as the outside of the shell, sometimes “fluted” of a different colour 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Escallop. It has been part of heraldic tradition almost from the beginning of the art, Henry III of England awarded Gules, 3 escallopes argent to Herbert de CHAMBERLEYNE in the 13th century, and it is present in the heraldry of almost all countries 8A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P299. It is believed that they were adopted as badges of those going to the Holy Land and can be found in the arms of many a crusading family. Hence Wade’s suggested association of the scallop with those that “complete long journeys to far countries” 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P91.
