The three main devices (symbols) in the Markham blazon are the demi lion, chief and cross patonce. The two main tinctures (colors) are azure and or.
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.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.3Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 27. Along with, argent, or silver it forms the two “metals” of heraldry – one of the guidelines of heraldic design is that silver objects should not be placed upon gold fields and vice versa 4A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P85. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.5Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53.
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. 6A 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.
The chief is an area across the top of the field 7Boutell’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, 8A 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.
No other symbol appearing in heraldry is subject to as much variation as the cross 9Boutell’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, typically involving patterning along the edges 10Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P67, or fanciful, decorative endings to the arms of the cross 11A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P128. The cross patonce is typical of these, whereby each arm of the cross expands and ends in a bud-like projection. These cross variations are probably largely for decorative effect, and to differentiate the arms from similar ones and hence their significance is that of the Christian cross itself.
