The three main devices (symbols) in the Cramp blazon are the cross crosslet fitchee, chevron and demi lion. The three main tinctures (colors) are azure, or and argent .
Azure is the heraldic colour blue, usually quite a deep, dark shade of the colour (there is a lighter blue that sometimes occurs, known as celestial azure). If colour printing is not available then it can be represented by closely spaced horizontal lines in a scheme known as “hatching” 1Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. The word is thought to originate from the Arabic lazura and it represents the colour of the eastern sky. It is also said to be the colour associated by the Catholic Church with the Virgin Mary and hence of particular significance 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P150.
Or is the heraldic metal Gold, often shown as a bold, bright yellow colour. It is said to show “Generosity and elevation of the mind” 3The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35. Later heralds, of a more poetic nature liked to refer to it as Topaz, after the gemstone, and, for obvious reasons associated it with the Sun 4Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 5A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P76-77.
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) 6Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
No other symbol appearing in heraldry is subject to as much variation as the cross 8Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 47. Mediaeval Europe was a deeply religious and Christian and many of the nobility wanted to show their devotion by adopting the symbol of the cross as part of the arms. Since no two arms could be identical there arose many variants of the cross. The cross crosslet is one of these, having an additional cross bar on each arm. 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Cross Crosslet Wade suggests that these additional crossing signify “the fourfold mystery of the Cross”. 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P103 The final addition fitchee simply means pointed, and indicates that the lower end is pointed, as if it is to be struck into the ground. 11A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Fitché
The chevron is one the major shapes used upon a shield, known as ordinaries. The inverted ‘V’ of the chevron is perhaps thought to have originated to represent a military scarf folded on the shield 12A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.13The Pursuivant of Arms, J. R. Planche, Hardwicke, London 1859. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 14The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
The demi-lion is a variant of the typical creature shown only from the waist upward. It can take all same poses and attitudes of its fully represented brethren and often appears to be emerging from some other device such as a fess or chief. 15A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Lion No special significance should be given to the demi appearance and it should be taken to have the same meanings and interpretations as the noble king of beasts itself.
