The four main devices (symbols) in the Arnway blazon are the saltire, crosier, fish and escallop. The two main tinctures (colors) are azure 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.
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.
The saltire is one the major ordinaries, large charges that occupy the whole of the field 5A 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! 6A Display of Heraldry, J. Guillim, Blome, London, 1679, P63
The middle ages was a deeply religious time, and since the bulk of heraldry was developed in countries that were almost entirely Christian it is no surprise that religious and church symbology was widely adopted for use in coats of arms. The crosier Is a typical such usage, being a staff carried by a Bishop in ceremony. As well the adoption of religious imagery for the nobility, the Church itself has made extensive use of arms, such Ecclesiastical Heraldry 7A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P600 is a major subject in its own right, somewhat less “martial” than that of the nobility and with its own terms and special meanings.
Fish in great variety abound in Heraldry, many different species inhabit coats of arms 8Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P150, although truth be told many of the actual images are sometimes indistinguishable, being shown as a stylised, and easily recognised “trout” shape 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P137 that a child might draw. The actual name used in the coat of arms may be some play-on-words or allusion to the family name, as in the famous arms of the de Lucy family, being “Gules, three lucies or”, 10Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 79 this being an ancient name for the fish we call today a “pike”.
