The four main devices (symbols) in the Enfield blazon are the inescutcheon, martlet, canton and mullet. The two main tinctures (colors) are or and gules.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.1Boutell’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 2A 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.3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”4The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 5Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P52. Although it may look like a French word it is normally pronounced with a hard “g” and may be derived either from the Latin gula (throat) or Arabic gule (rose).6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P154
The escutcheon simply represents smaller shield shapes included within the shield, and its close relative, the inescutcheon is just a larger version occupying most of the field. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Escutcheon There is no particular significance that can accorded to the escutcheon itself, but attention should be paid to the colour and devices that are borne upon it. The escutcheon may also be added to an existing coat of arms either as recognition of some additional honour (an escutcheon of augmentation”) or in the case where arms that are already quartered are to be combined an escutcheon with the new arms may be placed overall (an ”escutcheon of pretence”). 8Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 126 & 141
The martlett is by far the most common bird to appear in British Heraldry, perhaps only equalled by the eagle, however it is not a species ever to be found in an ornithologists handbook! The word itself is though to have come from the French word merlette, the female blackbird and itself a similar type of charge used in French Heraldry. 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Martlet. Over time the image has become quite stylised, without visible legs or distinctive feathers. Wade suggests that this representation arises from “the appearance of the bird of paradise to ancient travellers” 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P79. Other bird species may be named in coats of arms (cornish chough is a frequent example) but in actual execution their appearance is often indistinguishable from the martlet.
“The canton stands very high among honourable bearings”, according to Wade, a noted symbologist 11The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P48. The canton is a square shape, normally occupying the dexter chief of the shield. An early example is SUTTON, Bishop of Lincoln in the 13th century, who bore “argent a canton sable”. It occupies less space than a quarter and hence is sometimes added to an existing shield to difference branches of the same family, or, when a charge is added to it, to indicate some honour has been recieved 12A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Canton. Wade remarks, that, in common with all square features can be associated with the virtue of“constancy”.
