The two main devices (symbols) in the Eastday blazon are the griffin and chief. 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.
In the mediaeval period there was no real percieved difference between real and mythical animals, after all, much of the world remained unknown and who was to say what strange and magical creatures existed in distant lands? As heraldry developed a whole menagerie of imagined creatures 5Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P164 came into being, and their various representations became more or less standardised in form and appearance. The griffin is perhaps the most common of these creatures, being a chimera with the body of a lion and the head and wings of an eagle. 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Griffin. It is most often in the pose known as rampant segreant, on its hind legs with claws and wings extended. Vinycomb has much to say on the subject of the griffin, perhaps summarised in his belief that it represents “strength and vigilance”.]7Fictitious & Symbolic Creatures…in British Heraldry, J. Vinycomb, Chapman & Hall, London, 1906, P150
The chief is an area across the top of the field 8Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 40. It appears in many different forms and can itself be charged with other charges and ordinaries, 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Chief, being treated almost as if it were a completely separate area. In its simplest form it can be clearly identified. Early examples include the award by Henry III of England to the knight Robert de MORTEYN BRETON of Ermine, a chief gules.
