The two main devices (symbols) in the Gott blazon are the griffin and wings. The two main tinctures (colors) are sable and argent.
Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 1A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Sable. In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 2Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 3The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
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) 4Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 5A 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 6Understanding 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. 7A 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”.]8Fictitious & Symbolic Creatures…in British Heraldry, J. Vinycomb, Chapman & Hall, London, 1906, P150
Wings are frequently observed in coats of arms. Unless otherwise specified they should be shown as eagle’s wings, with a realistic appearance. 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Wing They can appear singly or in pairs, in which form they are very often found in the crest, which rests above the shield in a full achievement of arms. Wade, quoting Quillim, suggests that the use of the wing on the shield signifies “celerity and protection or covering”. 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P73
