The two main devices (symbols) in the Elworth blazon are the fesse embattled and chamber piece. The two main tinctures (colors) are sable and or.
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.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.4Boutell’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 5A 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.6Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53.
The fesse is a broad horizontal band across the centre of the shield, in very ancient times it was said to occupy one third of the area height of the shield 7A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P117, however it soon became somewhat narrower. This created an opportunity to add decorative edging to the band, of many forms, and to very pleasing artisitic effect, at least close up – it must be admitted that at distance some of the forms are hard to distinguish! An edge which is decorated like the top of a castle wall is said to be embattled, or sometimes crenelle, from the original French. (In castle building terminology the parts of the wall that stick up are known as merlons, and the resulting gaps as crenels). A whole sub-section of heraldic terminology has sprung up to describe whether these crennellations appear on which edges, whether they line up or alternate, have additional steps or rounded tops. The interested reader is directed to the reference for the full set! 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Embattled For obvious reasons, use of this decoration is to be associated with castles and fortified towns, an early authority, Guillim suggest also some association with fire, but with out clear reason 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P41. In all, this is one of the more common, and most effective and appropriate of the decorative edges.
Given the martial nature of the origins of Heraldry, in the identification of knights and men-at-arms it can come as no surprise that mediaeval weaponry of all types are frequently to be found in a coat of arms 10Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 89. The cannon is depicted as we might expect, if mounted the carraige may be a different colour. 11A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Guns We need look no further than the military connection for any meaning in this device.Chamber piece is simply an alternative name for the barrel of a cannon
