The four main devices (symbols) in the Leek blazon are the saltire, annulet, lion and fleur-de-lis. 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.
The saltire is one the major ordinaries, large charges that occupy the whole of the field 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Saltire. Arguably one of the best uses of this device is that of the St. Andrews Cross, a white saltire on a blue background found on the Scottish flag. The saltire is obviously closely related to the Cross, and Wade in his work on Heraldic Symbology suggests additionally that it alludes to “Resolution”, whilst Guillim, an even more ancient writer, somewhat fancifully argues that it is awarded to those who have succesfully scaled the walls of towns! 7A Display of Heraldry, J. Guillim, Blome, London, 1679, P63
For easy recognition of the items on a coat of arms, and hence the quick identification of the owner, bold simple shapes are best. Hence, simple geometric shapes are often used for this purpose 8A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146xz`, and the annulet is a good example, being a circular ring of any colour. They also appear interlaced or one within the other, both of which are very pleasing additions. Wade believes that these were one of the symbols of ancient pilgrims. 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P19
The art of heraldry would be significantly poorer if we were without the lion in all its forms. Most general works on Heraldry devote at least one chapter solely to this magnificent creature and its multifarious depictions 10A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P172 11Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 63 12Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P140. Some of the earliest known examples of heraldry, dating right back to the knighting of Geoffrey of Anjou in 1127, where he is shown with six such beasts upon his shield 13A Treatise on Heraldry, J. Woodward, W & A.K Johnston, Edinburgh & London, 1896, P45 .The great authority on heraldic symbology, Wade, points out the high place that the lion holds in heraldry, “as the emblem of deathless courage” 14The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P60, a sentiment echoed equally today.
